Aluminum Gasket: The Ultimate Guide

I know you are probably wondering how to choose aluminum gasket. Or, you would like to know where you can use aluminum gasket. Well, this guide explores everything about aluminum gaskets – keep reading to learn more.

What Is Aluminum Gasket?

A gasket refers to a seal made of flexible material that inhibits liquid or gas leakage between two surfaces.

That said, gaskets made from Aluminum are Aluminum gaskets. They are mainly recommended for applications that require high pressure.

You are likely to come across gaskets in a variety of industrial applications. Their main purpose is to provide a tight seal between two joined parts.

Gaskets work by sealing the gap between parts whose surface tolerance would result in leakages either from or into the joined parts.

Uses Of Aluminum Gasket

The main function of an Aluminum gasket is to seal a gap between two surfaces.

As such, the seal prevents oil, water, gas, and fuel leakages among other products that are under pressure.

If something requires a seal and cannot be moved, it is most likely using a gasket.

Aluminum Gasket

Aluminum gaskets are used in a variety of industrial applications such as gas, food processing, plumbing, and machinery just to mention some.

Their ability to withstand extreme temperatures and pressure has facilitated the functioning of the current advanced technology.

For Aluminum gaskets to function as desired, there must exist a significant amount of pressure between the joining parts.

The pressure can be achieved by using fasteners and screws.

Aluminum is malleable and this explains why an Aluminum gasket is capable of meeting several design requirements.

Advantages Of Aluminum Gasket

One of the major advantages of the Aluminum gasket is the prevention of leakages in both extreme temperatures and pressure.

Also, Aluminum gaskets act as safety equipment by managing applications that use gas or fluid systems functioning under high pressure.

Aluminum Gasket

In addition to that, this device reduces any risks of contamination by providing a tight seal.

Aluminum being a non-corrosive material is beneficial in applications where corrosion would otherwise affect the other element.

It has the ability to resist corrosion owing to passivation.

To get more clarity on the term, passivation is a process that involves coating the metal with a thin film.

This is done to prevent Aluminum from the effects of chemical procedures.

When you want to save on costs, you’d want to consider an Aluminum gasket since it has minimal maintenance requirements.

As a matter of fact, Aluminum is a lightweight material.

This means that the transport and shipping costs will be greatly minimized for Aluminum gaskets.

And I must tell you that Aluminum gaskets don’t lose their properties or quality when undergoing recycling.

It is also a fairly ductile material, a property that allows it to form different shapes without breaking.

So generally, all these properties contribute to the final costs which tend to be cheaper as compared to gaskets made from other materials.

Aluminum Gasket Material Grade

Gaskets are categorized according to several variations such as intended use, cost, anticipated exposure to chemicals or corrosives, and materials.

Aluminum material has three main material grades for gasket applications; 3003, 1100, and 6061.

Others include 1060, 5086, 5154, and 5052.

The type of grade you select defines the end-use application as well as the price.

Each one of these grades has unique benefits and properties.

For example, 1100 costs are lower as compared to 6061. However, it is unsuitable for high-temperature applications.

On the other hand, when producing solid gaskets, stronger alloys will be needed.

Normally 3003 and 5052 would be suitable for such applications.

Not only is the 3003 aluminum readily weldable but also can be used in several applications.

However, it has less corrosion resistance as compared to 1100 and 6061 aluminum.

The 1060 and 6061 alloy aluminum grades are normally ideal when producing high-end products.

This is because they have a higher-yielding and tensile strength thus facilitating the use of gaskets in high-performance applications.

Given that the 6061 aluminum grade has better resistance to corrosion than the 3003 aluminum, it can be used in high humidity situations.

1100 aluminum is made with 99% min purity and this explains why it’s considered to be the purest form of aluminum.

Not only does it have great ductility but also workability making it a suitable option for difficult forming procedures.

You also need to have it in mind that it is best for applications that need thermal conductivity.

Other than that, Aluminum 1100 can easily be shaped into a variety of products and shapes.

This explains why it is used in several applications and industries including lighting, construction, and plumbing among others.

Types Of Aluminum Gaskets

  • Natural O type aluminum gasket
  • Ring aluminum gasket

How To Choose Aluminum Gasket

When choosing an aluminum gasket, there are certain considerations that need to be made to achieve maximum efficiency.

Aluminum Gasket

To begin with, you want to start by knowing the type of gasket you want.

Some of the popular types of gaskets include;

  • Solid gaskets
  • Spiral wound gaskets
  • Rubber and plastic gaskets
  • Kammprofile gaskets
  • Jacket gaskets
  • Silicone gaskets

Having chosen your ideal type, it’s time to test its ability to withstand different temperatures and weights.

Conduct this evaluation under different pressures by using a hot compression test.

Also, it is important to test the chemical resistance of your gasket.

Be sure to conduct this test using the corrosive fluid it will be working with in order to know the reaction.

As a rule of thumb, it’s important to know the type of liquid you will be using when choosing an aluminum gasket.

Another important tip is selecting the right type of aluminum material grade.

Your choice will depend on the use of your aluminum gasket.

For example, the 6061 aluminum is great for producing high-end products.

On the other hand, aluminum 1100 is not a suitable option for use in high-temperature applications.

If you want to make a wise selection of the aluminum gasket material, trust me you will need to understand the properties of the aluminum material grade.

One last related piece of advice, be sure to consider the roughness of the sealing surfaces.

Remember, impurities will be filled up the sealing surface to prevent leakage.

To sum up, you will not only need to consider;

  • The conditions and environment of the operation (operating pressure and temperature)
  • Compatibility of the medium
  • Type of material grade
  • Mechanical features of the joint

Not forgetting to consider the maintenance of the joint as well as the properties of the type of gasket you have chosen.

Having done these, you can proceed to contact your manufacturer.

Aluminum Gaskets Vs. Non-metallic Gaskets

Gaskets can either be metallic, non-metallic, or semi-metallic. Aluminum gaskets are categorized under metallic gaskets.

Aluminum gaskets

Normally, metallic gaskets are either fabricated from one metal or several metals combined and used for high-quality surface sealing.

Aside from that, not only do aluminum gaskets have the ability to resist high temperatures and chemical exposure but also high pressures.

That said, aluminum gaskets are widely used in high-temperature, medium, as well as high-pressure applications.

Non-metallic gaskets are manufactured from mica sheets, fiber sheets, glass fibre, compressed non-asbestos sheets, and ceramic fibre among other materials.

As compared to the aluminum gasket, non-metallic gaskets have greater corrosion resistance.

non metalic gaskets

non metalic gaskets

In addition to that, it is easier to compress non-metallic gaskets under bolt load.

For that reason, they are not only used in high corrosive applications but also in several other low-pressure applications such as;

  • Compressors
  • Pipe flanges
  • Heat exchanges
  • Bonnet valves

Not much needs to be said, aluminum gaskets are ideal for extreme temperatures and pressure.

Non-metallic gaskets are suitable when using highly corrosive materials.
