Alloy C7025 is a second generation, high performance alloy whose strength comes from an age hardening heat treatment similar to that used for the beryllium coppers. With stress relaxation resistance comparable to Be-Cu alloys C170/C172 (see Olin 170, Alloy Digest Cu-615, July 1998, and Olin 172, Alloy Digest Cu-621, August 1998) and conductivity almost double that of brass, C7025 is well suited to high-reliability connector applications. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as joining. Filing Code: CU-631. Producer or source: Olin Brass.
