BRUSH ALLOY 174 beryllium copper is a family of alloys designed to allow denser packaging, miniaturization, higher currents and higher operating temperatures in electrical and electronic applications. It offers improved electrical and thermal conductivity, superior resistance to stress relaxation at elevated temperatures and better formability than competitive alloys, BRUSH ALLOY 174 is the preferred spring material where traditional copper-base alloys are inadequate. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming and joining. Filing Code: Cu-509. Producer or source: Brush Wellman Inc.. See also Alloy Digest Cu-578, November 1992.
