Description

The gold-silver-nickel material AuAg26Ni3, also Au71Ag26Ni3 or 71Au26Ag3Ni, exhibits good corrosion behavior as well as good wear behavior. The alloy is used for sliding contacts (monolithic contact spring material), switching contacts, plug contacts, tapping contacts. It is ductile, corrosion-resistant, oxidation-resistant. AuAg26Ni3 is machinable, roll-cladable, and can be separated from the gas phase conditionally. The alloy has increased resistance to material migration and is relatively hard and abrasion resistant.
