An alloy made of nearly equal amounts of chromium, cobalt and nickel resists fracture even at extremely cold temperatures, which could make it useful for building spacecraft
December 14, 2022
The alloy of chromium, cobalt and nickel (CrCoNi) is the toughest material ever created, with properties that allow it to be used in the manufacture of aircraft or spacecraft.
Toughness is a measure of a material’s ability to resist fracture and is distinct from hardness, which is a measure of a material’s ability to withstand deformation. For example, you can’t make a dent in a diamond, which is known to be the hardest material ever discovered, but you might be able to break one. …
