Olin 170 has a relatively high beryllium content compared to the whole class of beryllium coppers, and has the ability to reach tensile strengths near 1380 MPa (200 ksi).
Processing
Most copper alloys achieve their properties through the addition of alloying elements and cold rolling. Beryllium copper alloys achieve their properties through alloying elements, cold rolling, and a precipitation hardening heat treatment. Before rolling to final thickness, beryllium copper is solution annealed, which puts the beryllium in solution within the copper matrix. After rolling to final thickness, the material is precipitation hardened via a low-temperature heat ...
