Properties of Titanium

·High Strength

In hydroforming titanium, hydraulic fluid exerts pressure. The metal sheet morphs into desired shapes. The metal’s yield strength measures at 434 MPa. In contrast, steel’s is 250 MPa.

·Low Density

Titanium’s density is significantly low. An impressive 4.5 grams per cubic centimeter (g/cm³) marks the titanium’s density.

Such parts require substantial strength. Yet, keeping weight minimal is paramount. Hydroforming processes capitalize on titanium’s density advantage.

·Corrosion Resistant

When exposed to air, titanium forms an oxide layer. The thickness is around 25 nanometers. Saltwater, chlorine, and acids don’t affect titanium.  The material tolerates harsh chemicals.


Moving on, titanium’s biocompatibility is extraordinary. The human body accepts titanium. Medical implants like hip joints and dental screws are common. Infections are rare due to the oxide layer. MRI and X-ray machines contain titanium parts.

Importantly, the metal is non-toxic. Body tissues interact safely with titanium. Surgical instruments also employ the metal.

·Good Ductility

Titanium’s ductility is commendable. Sheets can stretch into thin wires. The material can bend without breaking. Grade 1 titanium is an exemplar, with elongation at 24%.


·High Melting Point

Titanium boasts a high melting point of 3,034°F (1,668°C).

·Excellent Fatigue Resistance

Titanium doesn’t get tired easily. Fatigue resistance means titanium parts last longer. Even under tons of stress, titanium parts don’t crack.

·Low Thermal Conductivity

With low thermal conductivity, titanium stays cool. Titanium, with cool composure, achieves excellent results in high-temperature environments.

·High Modulus Elasticity

Titanium springs back into shape with ease. A high modulus of elasticity – 15.2 x 10^6 psi – helps.

Basic Principles

Fluid Pressure

In Titanium hydroforming, liquid force shapes titanium. Imagine, a pump shoots water at 40,000 psi. Consequently, the super-strong metal bends like clay. Hydroformed titanium has strength and flexibility.

Notably, pressure and time are key. Indeed, experts use 10-15 seconds of pressure to avoid cracks.

Die Set

Next, the die set takes the stage. The die set is like a mold. Imagine cookie cutters for titanium. Initially, experts pick a die made of hard steel or carbide.

Then, the titanium sheet sits inside the die. Now, the pumped water from earlier pushes the titanium into the die shape. After that, machines press the die set tight.

Material Expansion

When water pushes on titanium, the metal stretches. Remarkably, it can stretch 1.5 times its size. Moreover, the metal can become 0.2 to 6” thick. Experts heat titanium to 1,650°F for easy stretching. Cooling makes the stretched metal super strong.

Uniform Force Application

In titanium hydroforming, a big machine pushes liquid at metal. The metal gets squished into shape. Plus, the machine doesn’t push too hard or too soft. ASTM B265 sets rules for the metal.

Most metal sheets start at 0.02” thick. The liquid’s force is the same all over.

High Precision

Super smart people love using titanium hydroforming. So, car and airplane makers use it too! A robot arm and sensors watch the metal. Next, a big squishy thing makes shapes.

For example, the Boeing 777 has a hydroformed titanium frame. In a Boeing 777, over 70,000 parts are hydroformed.

Rapid Forming

Make things faster with hydroforming! Use a punch to shape metal, and then squish it with liquid. A part is born in 10 seconds. ISO 21329 helps people do it right.

Hydrostatic Pressure

Hydrostatic pressure is like a strong handshake for metal. In hydroforming, liquid shakes hands with metal. The squeeze makes perfect shapes. Think of a balloon getting air. Liquid fills up a metal pocket.

Different Techniques

o   Tube Hydroforming

Engineers shape hydroformed titanium tubing using special machines. Next, a strong liquid pushes inside the tube. That way, the titanium stretches into the shape of a mold.

Additionally, the mold keeps the titanium steady. Common tube sizes are 3/8” and 5/8”. Hydroforming CP2 titanium, a popular grade, shapes well. Amazingly, the tubing gets super strong.

o   Sheet Hydroforming

In this method, sheets of titanium undergo the same magic. However, instead of a tube, large sheets get shaped. First, the machine places the sheet on a mold. Then, high-pressure liquid pushes the titanium down.

Consequently, hydroforming CP2 titanium sheets can cost more than tubes. The sheets can be 0.5 to 150 mm thick.

o   High-Pressure Hydroforming

Here, the liquid pressure is super high, often up to 10,000 PSI (pounds per square inch). Notably, titanium changes shape faster at these high pressures.

But, extreme care is needed to avoid cracks or damage. Titanium tubes and sheets both undergo high-pressure hydroforming. Specifically, complex shapes are easier to make. Experts like this method for making car exhausts and bicycle frames.

o   Low-Pressure Hydroforming

In this process, machines use water. Yes, water! But, not too much pressure. Here, titanium hydroforming takes a main role. Next, titanium sheets become amazing shapes. Imagine car parts or plane bits.

All of them can be made using 5,000 to 10,000 psi. Experts call this technique T.H.F. No heat needed. Think of strong, light, and super cool designs.

o   Parison Hydroforming

In contrast, this method uses a thing called a “parison”. A parison is like a soft tube of titanium. Then, with air and water, the parison grows into shapes. Imagine balloons! This method needs 10,000 to 20,000 psi.

Titanium turns into bicycle frames or music instruments. Parts made are thin but mighty. Above all, factories love this method for saving metal.

o   Hydro-Mechanical Deep Drawing

Here, the focus is on deep, complex shapes. First, machines use liquid and a punch. The liquid is often oil. The punch helps to shape titanium.

Then, parts like kitchen sinks or engine casings come to life. With 15,000 to 30,000 psi, the titanium bends and curves. Precision is key here. Deep drawing makes strong, sleek parts.

The Titanium Hydroforming Process!

Step-by-Step Procedure

§  Loading Titanium

Experts place a Titanium sheet onto the die. Next, technicians secure the sheet with a hydraulic ram.

§  Pressurizing Fluid

Now, the chamber fills with hydraulic fluid. The fluid gains pressure – typically 15,000 PSI. More pressure can be up to 100,000 PSI. That’s a force! The fluid pushes on the Titanium sheet. This makes it move, and it gets ready to change shape.

§  Expanding Titanium

The fluid’s force makes the Titanium grow bigger. Engineers call this “bulging.” With bulging, Titanium takes the die’s shape. Titanium Grade 2 is a top pick for car parts. Grade 5 is excellent for planes. Using the correct grade makes a world of difference in results.

§  Titanium Forming

The Titanium stretches into its new form. TDF (Titanium Drawing Fluid) makes the process smoother. That helps create complex designs.

§  Releasing Pressure

Pressure goes down, and the fluid flows away. The Titanium stops stretching. The new part sits snug in the die. Skilled hands manage pressure with care. The part’s quality is now set in stone. Masterful control defines the best outcomes.

§  Unloading Component

The hydraulic ram pulls back. The new part lifts out of the die. The air is electric. With the part out, one can see the change. For strong parts, engineers favor Grade 23 Titanium. The material does not fail.

§  Trimming Excess

Artists with tools, technicians trim extra Titanium. CNC machines are often the tool of choice. Clean edges make for a perfect part. Without excess, the part fits right every time. Precision is not optional; it’s essential.

§  Final Inspection

The part undergoes a careful look-over. Microscopes and gauges check for flaws. Engineers demand nothing less than perfection. Measurements must be within 0.005”. Anything more is not accepted. Quality assurance is the guardian of excellence.

§  Component Cleaning

Sparkling clean is the goal. The part goes into a special bath. Acids and solvents remove oils and grime. Scrubbing and ultrasonic waves do their work. Titanium comes out gleaming. No dirt can hide. Cleanliness ensures the best fit and function.

§  Component Finishing

The final step is a masterpiece. Surface treatments add the finishing touch. Electro-polishing makes the Titanium shine. Powder coating adds color.

The part is now ready for the world. Industries worldwide await with bated breath. Titanium hydroforming has once again achieved the pinnacle of manufacturing marvel.

Critical Parameters and Controls

o   Pressure Control

In Titanium hydroforming, controlling pressure is crucial. Initially, pump PSI should be around 5,000. Then, experts gradually increase it up to 60,000 PSI for optimal shaping. A relief valve keeps everything safe.

o   Material Thickness

Selecting the right material thickness is vital. Thin sheets, around 0.5 mm, are for delicate designs. For sturdy parts, 2.5 mm to 6.4 mm titanium sheets work best.

o   Die Alignment

Die alignment deserves keen attention. Precision ensures the shaped titanium fits the exact specifications. Typically, experts use micrometers and laser alignment tools.

A tiny misalignment, even 0.001”, can ruin the entire process.

o   Fluid Temperature

In the hydroforming process, fluid temperature has a key role. Generally, keeping it between 68 to 108°F is best. Too hot, and titanium becomes too soft.

Too cold, and shaping gets hard. Maintaining optimal temperature prevents wastage and ensures excellent titanium pieces.

o   Cycle Time

Optimizing cycle time boosts productivity. On average, cycle times range from 10 to 30 seconds. Shorter times, less than 10 seconds, risk defects. Longer times, over 30 seconds, decrease output. Expert hydroformers know striking a balance is paramount.

An optimized cycle time is the magic ingredient for quality, efficiency, and cost-effectiveness in Titanium hydroforming.

o   Material Temper

A softer titanium, like Grade 1, bends easily. However, Grade 5 is tough, perfect for strong parts. Companies test for Rockwell hardness, between HRC 36-45.

Careful control ensures the titanium doesn’t crack. ASTM standards, like ASTM B265, guide professionals in material selection.

o   Die Surface Condition

Smooth dies prevent marks on the final product. Moreover, dies with PVD (Physical Vapor Deposition) coatings lessen wear. Typical hardness is about 3500 HV.

High-speed steel (HSS) dies, though pricier, offer better performance. HSS dies make more parts before wearing out. Consistent maintenance safeguards die quality, essential for impeccable outcomes.

o   Material Grain Direction

The metal’s atoms form patterns, like tree rings. Correct alignment makes parts less likely to break. Misalignment can cause failures under pressure.

ISO 9001 standards help in maintaining proper alignment. Aerospace industries keep a keen eye on grain direction. Safety in flight depends on error-free alignment.

o   Lubrication Level

Lubrication decreases friction during forming. Friction generates heat, which can weaken the metal. A common lubricant is polyalkylene glycol (PAG) oil.

PAG oil helps titanium glide smoothly. Manufacturers apply specific amounts, usually in mL, as too much can create defects. Proper lubrication is a game-changer in titanium forming.

o   Post-Forming Treatment

Products undergo heat treatment to increase toughness. Moreover, cold working enhances strength. Stress relief annealing removes internal stress.

Tensile strength often reaches around 130,000 psi. Precise handling during treatment guarantees the best final product.

Challenges and Solutions

·Wrinkling Control

In Titanium hydroforming, wrinkles are bad. Hydraulic pressure, typically 40,000 PSI, shapes the metal. With too much pressure, wrinkles happen.

Precision control systems, coupled with high-tech sensors, monitor pressure. Moreover, CNC tooling makes exact shapes. Variable blank holder force (VBHF) ensures metal stretches just right.

·Tear Prevention

Titanium is strong but tears easily. Now, let’s talk about tear prevention. Lubrication is key. Surface coatings, like titanium nitride, make titanium glide.

Also, hydroforming uses fluid pressure. So, experts pick the right fluid. Tooling radii are important too. Bigger radii, above 3mm, avoid sharp bends. Next, gentle pressure increases prevent tearing.

·Reducing Springback

The titanium bounces back and loses shape.Solution annealing helps. Heat the titanium to 1,300°F, and then cool it. Also, alloy selection counts. Grade 5 titanium has low springback. Next, accurate dies matter. Design dies with compensation for springback.

·Over-Expansion Mitigation

Over-expansion stretches titanium too much. Consequently, parts don’t fit.The punch speed is crucial; 3” per minute is a good start. The punch is the shaper.

Additionally, annealing helps. 1,650°F is the magic number for titanium. Controlled fluid pressure is also vital.

·Die Wear Reduction

With titanium hydroforming, the dies shape the metal. Importantly, surface coatings keep dies healthy. Chromium and titanium nitride are stars here.

Regular maintenance is paramount.

·Maintaining Tolerance

Setting the hydraulic pressure at 400-600 MPa is crucial. Moreover, sheet thickness between 0.6 mm to 3 mm is optimal. Notably, tool radii influence metal flow. The die cavity should be -0.05 mm for accurate results.

Lubricants, like soap-based ones, reduce friction. In addition, gas pressures must range from 90 to 220 psi. Keeping tabs on temperature, around 400°F, ensures supreme quality.

·Managing Costs

The use of Grade 1 or Grade 2 titanium sheets curtails costs. Also, optimizing hydraulic system pressures prevents energy waste. Consequently, pre-cut blanks streamline production. In essence, sheet sizes of 100×200 mm reduce wastage.

Investing in top-notch CAD/CAM software mitigates design flaws. Quick die change systems (QDC) lower tool costs and shorten setup times.

·Ensuring Consistency

Adjusting the V-die opening, ideally at 6 to 12 times the sheet thickness, is paramount. Additionally, synchronizing ram speed and pressure ensures uniform forming. Remarkably, digital monitoring systems track parameters in real-time.

Also, annealing treatments at temperatures of 700-800°C improve material workability.

·Optimizing Cycle Times

Integrating robotic arms can cut down the loading times to mere seconds. Additionally, adopting servo-driven pumps accelerates hydraulic performance. Employing high-speed presses, with 100-200 strokes per minute, will rocket the productivity.

Ultrasonic testing on-the-fly during production minimizes downtime. Incorporating Six Sigma methodologies, such as DMAIC, fine-tunes processes for maximal output.

·Safe Handling

Donning fire-resistant garments protects against sparks. Additionally, employing HEPA filters curtails titanium dust exposure. Moreover, automated material handling systems negate human contact. Storing titanium sheets in dry areas with a relative humidity below 50% prevents reactions.
