Berylco 14 is a beryllium copper alloy with 0.4% Be. The alloy is an automotive industry favorite similar to Berylco 10 (see Alloy Digest Cu-6, April 1953) but with nickel substituting for cobalt. The alloy has high thermal and electrical conductivity, good strength, and superior high-temperature performance. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength as well as fatigue. It also includes information on heat treating. Filing Code: CU-642. Producer or source: NGK Metals Corporation.
