Description

C17200 (CuBe2) is the most commonly specified beryllium copper and offers a wide combination of properties including good electrical conductivity, good formability and very high electrical and mechanical properties after heat treatment. This grade is supplied in age hardenable tempers TB00 (A). These require heat treatment to produce the alloy’s maximum strength and conductivity. The solution annealed TB00 (A) temper contains no cold work and is the softest temper.
