Nickel Silver (Copper-Nickel-Zinc Alloys)

Due to its nickel content, nickel silver is particularly hard and corrosion resistant.

As is the case with all copper alloys, nickel silver can only be hardened mechanically, e.g. by cold forging or rolling. Heating (annealing) over approx. 500 °C re-softens the material.
