Beryllium Bronze C17500
UNS C17500
Description
Beryllium bronze C17500, also known as CDA175 and Alloy 10, offers good strength and hardness characteristics coupled with conductivity in the range of 45-60 percent of copper with ultimate tensile and hardness properties. Due to the additional alloying element of cobalt, it has a slightly lower thermal conductivity and melting temperature. C17500 is available in wrought product forms and can be supplied fully hardened by our producing mill.
