Strongest Metals: An Introduction

Which metal is the strongest metal on earth? One of those questions that appears straightforward but is pretty difficult. Direct comparisons based on strength don't hold when it comes to metal. Why? Because there isn't a single, scale for measuring strength. There are four most important parameters that contribute to the general concept of metallic strength. I will describe these four forms of strength before providing some analysis and comparisons of the metals with the highest levels of strength.

Tensile Strength

A material's capacity to withstand tension is referred to as its tensile strength. In other words, it considers how much force is necessary to stretch or tear anything apart. In comparison to a material with great tensile strength, one with low tensile strength would be easier to rip apart.

Compressive Strength

The ability of a substance to survive being crushed together is known as its compressive strength (compressed). An external force is applied to a material to test its compressive strength, measuring how much it can withstand size reduction. The Mohs Hardness Test is a widely used method for determining compressive strength.

Yield Strength

It describes a material's capacity to sustain bending or permanent deformation. It's a technique for determining a material's elastic limit. often determined using a bend test that applies tension to the two ends of a beam or bar while they are held in place. The goal is to determine the amount of tension needed to exceed the material's yield point or the point at which the material won't deform once the stress is removed.

Impact Strength

The term "impact strength" describes a material's capacity to withstand force without breaking or fracture. In other words, it's a technique for figuring out the maximum amount of energy that a material can absorb by impact.

List of Strongest Metals


Tungsten, often known as "heavy stone" in Swedish, is the world's strongest metal. In 1781, it was recognized as a novel element. It is frequently used to manufacture paints, bullets, missiles, electron and television tubes, glass to metal seals, and metal evaporation equipment.


The most popular and second-strongest metal in use today is steel. It is an iron and carbon alloy with trace elements of silicon, phosphorus, oxygen, and manganese. It is one of the most recycled metals and is regarded as a necessary metal in engineering and building.


Chromium is a steel-gray, strong, glossy metal that is frequently used as an alloy in the production of stainless steel. Because of its hardness, chromium is utilized in the plating of automobiles and is a vital dietary supplement that is frequently found in organ meats, wheat germ, mushrooms, and broccoli. It also makes this list due to its hardness.


There are five stable isotopes of titanium that are found naturally, and it was identified in 1790. Titanium has a high strength-to-weight ratio and resistance to corrosion despite being a poor conductor of electricity. It is frequently utilized in the aerospace industry, as well as in design and architecture, medical equipment, and several everyday items.


Iron is the most common element on Earth and the sixth most available element in the universe. Steel and steel alloys like carbon steel are produced using it. Additionally, it is essential in the production of rifle barrels, bicycle chains, bicycle chains for bicycles, and electrical pylons.


The transitional metal vanadium was given the name of an ancient Norse deity. To create steel additives that are shock- and corrosion-resistant, the majority of the vanadium is alloyed with iron. The refinement of uranium for nuclear use and the production of vehicle parts like pistons both depend on it.


One of the costliest rare earth metals, lutetium is never discovered in its pure form on earth. It was founded in 1907 and is called after an old name for Paris. In the processes of hydrogenation, cracking, alkylation, and polymerization, it is frequently utilized as a catalyst.

Interesting Fact

  • Except for mercury, which is a liquid at ambient temperature, all metals are solids.

  • Contrary to what you may have read in books and seen in movies, most radioactive substances don't glow at night. However, some radioactive metals either emit radiation that interacts and generates visible light or glow from internal heat.

Solved Problems

1. What factor decreases the tensile strength?

Ans: When the temperature increases the tensile strength decreases due to softening of material at very high temperatures. We use UTM (Universal Testing Machine) to check the tensile strength of a material.

2. What is the impact strength of any material?

Ans: Impact strength, which is measured in terms of energy, is a material's capacity to sustain an abruptly applied load. Frequently determined using the Charpy impact test or the Izod impact strength test, both of which assess the force necessary to break a sample.


If we want to compare the metal we have to consider all its strengths and properties, only then we are able to find out which is the strongest metal in the world. As we saw every metal has its own unique strength that makes it different from other metals. And all these strengths also help us to understand where we can use which metal according to the requirement.

FAQs on Strongest Metals

1. What are the top 5 strongest metals?

Tungsten, Iridium, steel, Osmium, Chromium, and Titanium are the top strongest metals but when it comes to the tensile strength of metals, tungsten tops all other metals with 1510 megapascals is the ultimate strength. The tensile strength can be calculated if we use a UTM machine for any material. In this test, the material is subject to tensile force which is applied by the machine until the material is separated into two parts known as fracture or break point of the material.

2. What is the heaviest metal?

Osmium is the heaviest metal, having over double the weight of lead when compared on a bulk-for-bulk basis. Gold has a specific gravity of roughly 19 1/4, while osmium has a specific gravity of about 22 1/2. Osmium is also the least heat-resistant metal, staying undisturbed by temperatures that would make platinum flow like water. Specific gravity means the ratio of a material's density to that of a standard substance, with air or hydrogen serving as the standard for gases and water serving as the standard for liquids and solids.

3. Is Tungsten stronger than titanium?

Tungsten is the strongest natural metal in terms of the tensile strength (142,000 psi). However, tungsten is a brittle metal that is known to fracture on contact, making it poor in terms of impact strength. The tensile strength of titanium, on the other hand, is 63,000 psi. However, titanium outperforms tungsten when you take into account its density and conduct a pound-for-pound comparison. As we know tensile strength can be measured by a UTM machine similarly you can also calculate the impact or compressive strength.
