C17200 Details:
C17200 Beryllium Copper
Cube2 - C17200 (CDA 172) Beryllium copper is the most commonly used beryllium copper alloy. Compared with it, it has the highest strength and hardness. Commercial copper alloys. C17200 alloy contains appr. With 2% beryllium, its ultimate tensile strength can exceed 200 ksi, and its hardness is close to Rockwell c45. At the same time, under the condition of complete aging, the conductivity is at least 22% IACS. c17200 also has excellent resistance to high temperature stress relaxation.
