| 1) Remark: The gold-silver material AuAg20, also Au80Ag20, 80Au20Ag, Au/Ag80/20, has a good corrosion behavior with a low wear behavior. It is used for switching contacts (switches and relays for currents up to 10 mA at voltages below 300 mV) and for connectors (recommended contact force> 100 cN). It is ductile, corrosion-resistant, oxidation-resistant. AuAg20 is machinable, platable by rolling, electrodepositable, and can be separated from the gas phase. It has higher hardness and better abrasion resistance compared to higher-grade gold alloys (load range 1). |
