Description

The platinum-nickel material PtNi8.5, also Pt91.5Ni8.5 or 91.5Pt8.5Ni or Pt/Ni91.5/8.5, is used as contact material for switching contacts (switches and relays for higher alternating current loads with long service life as with PtIr5 , but for DC loads or AC loads with mains-synchronous switching instants) as well as for straps use. When switching DC circuits, PtNi8.5 has the additional advantage of a small areal material creeping from one contact to another. They are particularly well suited for currents above 100 mA at voltages greater than 12 V when long lifetimes are required. The material is ductile, corrosion-resistant, abrasion-resistant and erosion-resistant. It is machinable, roll-cladable and conditionally deductible from the gas phase.
