Brinell Hardness of Beryllium Copper

The Brinell Hardness of Beryllium Copper constant displays the value of the Brinell hardness for beryllium copper UNS C17200 (150 BHN). 

Brinell hardness test determines the ability of a metal to resist permanent indentation deformation through the scale of penetration of an indenter that is loaded onto a material sample. Brinell hardness is one of several definitions of hardness for materials science.

Beryllium copper, also known as beryllium bronze, is a copper alloy that contains 0.5-3% beryllium. It is the strongest and hardest of any copper alloy. The Brinell hardness of beryllium copper UNS C17200 is 150 Brinell hardness numbers (BHN).
