Description

The platinum-iridium material PtIr20 (in the literature also: Pt20Ir, Pt80Ir20, Pt / Ir80 / 20) is used for switch contacts as well as for laboratory devices or structural components such as eg. B. 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. PtIr20 is used for switches and relays for higher AC loads (currents over 300 mA at voltages above 12 V) with a long service life. Another field of application for this material is the use as a potentiometer alloy.
