BERYLCO NICKEL ALLOY 440 is an age-hardenable nickel-beryllium-titanium alloy that offers high strength, excellent spring properties outstanding formability, good high-temperature mechanical properties, and resistance to corrosion and fatigue. Complex shapes can be produced in the solution-treated (soft) condition and then aged to a minimum tensile strength of 215,500 psi. It is used for mechanical and electrical/electronic components in the temperature range -320 to 800 F. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Ni-94. Producer or source: Kawecki Berylco Industries Inc.. Originally published September 1964, revised September 1975.

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.

Berylco 7 is beryllium copper alloy with 0.3% beryllium. The alloy has high conductivity, fatigue strength, and wear resistance and is nonmagnetic. This datasheet provides information on composition, physical properties, elasticity, tensile properties, and shear strength as well asfatigue. Filing Code: CU-641.
