|
Description |
CuBe1.7is a precipitation hardening Cu-alloy. In the heat treated normal condition it has extraordinarily high hardness and strength with good electrical and thermal conductivity. In comparison to CuBe2, machining and processing is somewhat easier, which can be an advantage in the case of complicated forms; however, the high degree of hardness of CuBe2 cannot be achieved. |
