PtIr30 soft annealed (+A)

The platinum-iridium material PtIr30 (in the literature also: Pt30Ir or Pt70Ir30) is used as contact material for switching contacts (switches and relays for higher alternating current loads with a long service life) as well as for laboratory devices or structural components such as satellite control nozzles that are mechanically stressed, thermally and corrosively heavily used. The mechanical, thermal and corrosive resistance increases with increasing iridium content. In an oxidizing atmosphere, increased weight loss occurs in platinum-iridium alloys. Further fields of application for this material are the use as potentiometer alloy as well as for clamping bands. The material is ductile, corrosion-resistant, oxidation-resistant up to 1000°C, abrasion-resistant, hardenable and resistant to high temperatures. It is non-cutting and machinable machinable, roll-clad and conditionally deductible from the gas phase.
