Overview
As a low beryllium alloy, C17510 resides at the lower strength end of the beryllium copper strength spectrum but in comparison has a substantial increase in electrical conductivity. The alloy processes and heat-treats like all beryllium coppers and can also be provided in a (HM) “Mill Hardened” temper.
