The world’s hardest metal is tungsten carbide. Although this metal is incredibly resilient, it is not unbreakable. Despite having a very high tensile strength—a material’s ability to resist breaking under tension—tungsten is brittle and may crack if repeatably dropped onto a hard surface.

Tungsten is:

• Ten times tougher than gold is tungsten.

• five times harder then Stainless steel.

• Four times as durable as titanium.
