Platinum Iridium alloy Introduction
Platinum-iridium alloy is platinum based iridium binary alloy, it is continuous solid solution at high temperature, and slow cooling to solid phase decomposition during 975 ~ 700 ℃, but the phase equilibrium process is quite slow. Iridium is volatile and oxidized, which can significantly improve the corrosion resistance of platinum. There are Ptlrl0, Ptlr17.5, Ptlr25, Ptlr30 and other alloys with high hardness, high melting point, high corrosion resistance and low contact resistance specialty. The chemical corrosion velocity is 58% of pure platinum and the oxidation loss is 2.8mg/g. It is a classical electric contact material used for the electric contact points of ignition contacts, high sensitivity relays and micromotors.Potentiometers and conducting rings and brushes for precision sensors such as aircraft, missiles and gyroscopes.
