Is Titanium stronger than diamond?

Titanium is not stronger than a diamond. In terms of hardness, Titanium is not harder than a diamond either. … The only advantage titanium has over steel is that it is a much lighter material. When compared to diamond, however, titanium does not come close in strength or hardness.

Is Titanium stronger than bone?

Putting in some typical dimensions and material properties we find that the stresses in a bone made from titanium alloy, for example, would be about 1.3 times higher than in a bone of the same weight, made from bone. But the titanium alloy is 5 times stronger so obviously its safety factor is much higher.
