What is the Strongest Metal in The World?

In this guide, you will learn two things about the strength of metals.

One, factors to look for in metal strength. Secondly, the guide compares metals’ yield strength and tensile strength.

But fast, let’s have a quick overview:

Factors Determining Strength of Metals

Metal Properties
Metal Properties

Usually, we evaluate metals’ strength based on 4 main attributes:

Tensile Strength of Metals

When you subject metal to a stretching force, it exhibits some resistance before any changes occur. A phenomenon called tensile strength.

Ideally, it refers to a point metal transitions from temporary to permanent deformation. With the knowledge of metal’s tensile strength, you can predict:

  • Metal’s ductile failure – usually, this occurs after subjecting the metal to tensional forces exceeding the yield point. Thereby, resulting in permanent deformation.
  • Brittle failure – it is a critical point for determining the tensile strength

The SI unit for metal tensile strength is:

  • Pascal (Pa)
  • Mega Pascal (MPa)
  • Giga Pascal (GPa)
  • Pounds per square inch (PSI)

Tungsten tensile strength is about 500,000psi. This is actually the highest for a metal in pure form. It can maintain strength at extremely high temperatures.

Yield Strength

It is force a metal should withstand just before deformation starts.

Usually, you can use yield strength to estimate possible elastic limits for metals. Remember, before a metal reaches the yielding point after removing a force or load, it will retain its original shape.

Therefore, when examining a metal, the yield strength denotes the upper limit. You will use this data to estimate the optimal force or load a metal can handle.

In today’s metal industry, carbon steel remains a metal alloy with the highest yield strength. The yield strength is about 260 MPa.

Compressive Strength

As you compress metal, the metal may resist forces deforming its structure. The maximum force it can withstand is compressive strength.

Of all metals available in the market, high carbon steel has the highest compressive strength.

Remember, the metal compressive strength varies depending:

  • Heat treatment
  • Chemical composition
  • Other special processing and treatment
Forces on Metal Testing
Forces on Metal Testing

A compressive force refers to the exact instance where deformation starts.

Impact Strength

It is the metals capability to withstand or resist abrupt force. The ability to resist force is the impact strength.

The change in the metal structure can either be cracking, or fracturing. Factors determining impact strength are:

  • Yield strength
  • Distribution forces
  • Volume
  • Elasticity

Comparing Metal Strength


Ideally, all metals exist in two main forms:

  • Pure metal – it is metal without impurities or other elements.
  • Alloy metal – here, you add other elements to pure metal. Usually, the main reason is to improve the chemical, physical and mechanical properties.
Pure Metal and Alloy
Pure Metal and Alloy

Therefore, while comparing metal strength, it is important to acknowledge whether you are using pure metal or an alloy metal.

Usually, the tensile strength, yield strength, comprehensive strength, and impact strength tend to fluctuate in metals. Therefore, at times arranging metals from strongest to weakest or vice versa can be challenging.

It can be easier if you focus on a single parameter say tensile strength or yield strength. With that background information, let’s compare the yield strength and tensile strengths of the strongest metals on earth:

Note: The figures below are estimates (Let your metal manufacturer provide verifiable data on various materials before purchase)
