Hardest materials ever is an alloy of chromium, cobalt and nickel

An alloy made of just about equal quantities of chromium, cobalt and nickel resists fracturing even at extremely chilly temperatures, which may make it helpful for constructing spacecraft

An alloy of chromium, cobalt and nickel (CrCoNi) is the hardest materials ever examined, and its traits may make it helpful within the development of plane or spacecraft.

Toughness is a measure of a fabric’s resilience in opposition to fracturing, and it isn’t the identical factor as hardness, which is a measure of a fabric’s capability to face up to deformation. For example, you’ll be able to’t put a dent in a diamond, famously recognized to be the toughest materials but found, however you may be capable of crack one. …
