What is the strongest kind of metal?

Answer 1

Strong can mean different things.

Carbide steel is strong and hard, but it can be shattered much more easily than you would think.

Titanium is extremely strong for its very light weight . . . perhaps 180,000 pounds per square inch (psi)

Some of the variety of stainless steels (CRSA, or Corrosion-Resistant Steel) are very strong, having a strength up to perhaps 200,000 psi.

Perhaps the strongest metal is Inconel 625, a super-alloy (mix of different metals and substances) that is used in parts of airplanes that cannot be allowed to break. Inconel 625 is composed of nickel, chromium, and molybdenum.

There are other Inconels with different numbers, but all of the Inconels are composed mostly of nickel, with chromium being in second place. The third metal can be many different metals, each of which makes a slightly different kind of Inconel.

The strength of Inconel 625 is well above 200,000 psi.
