Platinum iridium wire is a platinum based binary alloy containing iridium. It is a continuous solid melt at high temperature. When it is slowly cooled to 975~700 ° C, solid phase decomposition occurs, but the phase equilibrium process is slow. Iridium is volatile and oxidized, which can improve the corrosion resistance of platinum. There are Ptlr10.Ptlr20Ptlr25Ptlr30 and other alloys, which have high hardness, high melting point, strong corrosion resistance and low contact resistance. The chemical corrosion rate is 58% of pure platinum, and the oxidation loss is 2.8mg/g. They are common electrical contact materials, and are used for electrical contacts with high ignition contacts of aeroengines, sensitive relays, and electric motors; Potentiometers and conductive ring brushes for sensors such as aircraft, missiles and gyroscopes.
Pt Ir wires are used as high oxidation resistance thermocouple materials and filament materials. Iridium wire and iridium alloy wire are mainly used in dry spark plug industry, aviation, chemical industry, crystal, electromechanical and other related fields (ignition electrode, high temperature thermocouple, electrical contact material, filament, high temperature resistance wire
