Standard Specification for Copper-Nickel-Tin Alloy, Copper-Nickel-Zinc Alloy (Nickel Silver), and Copper-Nickel Alloy Plate, Sheet, Strip, and Rolled Bar
This specification establishes the requirements for copper-nickel-tin, copper-nickel-zinc, and copper-nickel alloy plates, sheets, strips, and rolled bars made from UNS C70600, C70620, C71000, C71500, C71520, C72200, C72500, C73500, C74000, C74500, C75200, C76200, or C77000 alloy.
Each product should be manufactured by hot or cold working, and annealed if required, to produce a uniform wrought structure that meets the specified temper properties.
This specification also contains information on the standard tempers for and tensile strengths of hot-rolled, cold-rolled, and annealed tempers.
In case of disagreements, the chemical composition is determined following appropriate methods listed here.
Grain size is the standard requirement for all products in the annealed tempers.
