Question

What is the strongest metal?

Answer 1

Metal:

• Metal is an electrically and thermally conductive substance, it can be synthesized or found naturally.
• Metals are mainly malleable or ductile.

Different types of strength: The strongest metal is selected based on strength. There are four types of metal's strength:

1. Compressive strength: It is possible to squeeze or compress metal. The material is tested by applying external pressure. For example, Styrofoam is easily squeezed and flattened with less compressive strength.
2. Tensile strength: Despite its strength, the metal resists tension and bending when pulled apart. For example, Taffy has a low tensile strength as compared to Graphene.
3. Yield strength: The ability of a metal to withstand permanent deformation or bending is measured by its elastic limit. For example, Maraging steel has a good yield strength and is used to build engine parts, fencing blades, and rockets.
4. Impact strength: Metal's energy absorption through impact is determined by its ability to absorb energy without shattering and fracturing. For example, Bulletproof glass has a high impact strength than normal glass.

Strongest metal: The selection of the strongest metal is based on its strength.

1. The strongest metal is Tungsten because of its highest tensile strength which is about $60\mathrm{Mpsi}/400\mathrm{GPa}$.
2. At high temperatures ($1500°\mathrm{C}$), it has high tensile strength.
3. It is so dense so that it can resist melting under extremely high melting.
4. It is used in the manufacturing of bullets and missiles because the Tungsten density gives the ability to penetrate through armor.
