This specification covers UNS N05500 nickel-copper-aluminum alloy rounds, squares, hexagons, rectangles, and forgings and forging stocks manufactured by either hot working or cold working, and cold-worked wire. The material should conform to the required mechanical properties in both aged and unaged conditions. Precipitation hardening is accomplished by holding the material at a high temperature, followed by furnace cooling and then air cooling.

1.1 This specification covers nickel-copper-aluminum alloy (UNS N05500) in the form of rounds, squares, hexagons, or rectangles, and forgings and forging stock, manufactured either by hot working or cold working, and cold-worked wire.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
