BRUSHFORM 290 is a specially processed, mill-hardened beryllium copper alloy having improved formability while maintaining the strength of other mill-hardened copper beryllium alloys. It was developed for current carrying springs requiring greater formability. It can be used in a number of applications formerly limited to heat treatable tempers. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming and heat treating. Filing Code: Cu-505. Producer or source: Brush Wellman Inc.. See also Alloy Digest Cu-650, July 2000.
