Description

The gold-nickel material AuNi5, also Au95Ni5, 95Au5Ni or Au/Ni95/5, is used for switching contacts (average loads in the current range up to 300 mA at voltages below 12 V), plug contacts and tapping contacts (standard material). It is ductile, corrosion-resistant up to 200 ° C, more resistant to abrasion against gold. AuNi5 is machinable, roll-cladable and conditionally separable from the gas phase. Due to the addition of nickel, the sticking tendency of the gold is somewhat suppressed. It has higher hardness and better abrasion resistance compared to higher-grade gold alloys (load range 1).
