Gold Nickel alloy

  • Gold nickel alloy bar is a binary alloy with nickel added to gold. It can be continuous solid dissolved above 850 ℃ and decompose into rich gold and rich nickel at low temperature. There are gold nickel alloys such as AuNi5, AuNi9, AuNi10, AuNi17.5 and AuNi18 alloys. They are made by vacuum induction furnace smelting and alloy solidification after water quenching. Alloys with an M content of less than 10% can be cold worked while content more than 18% can be cold and hot worked after softening. Gold nickel alloy is widely used as light and medium load electric contact material; AuNi18, AuNi45 and etc. are used in electric vacuum solders and brazed aero-engine blades.

  • The gold nickel complex alloy is composed of chromium, iron, yttrium, gadolinium and zirconium with gold nickel base .It has the characteristics of low resistance temperature coefficient, abrasion resistance and long life. It is suitable for winding and brush materials with low and medium resistivity. AuNi9 can be turned into AuNiGd9-0.5, Au-NiY9-0.5 alloy with addition of a small amount of rare earth element gadolinium and yttrium and AuNiCr5-1, AuNiCr5-2 alloy with addition of chromium. They are both alloys with large use quantity.
