80/20 Pt/Ir wire
80/20 Pt/Ir Wire Platinum-iridium alloys are tough and ductile. A small addition of iridium can improve the microstructural stability of platinum at high temperature without significantly affecting the mechanical strength and forming properties of platinum. Almost a wide variety of platinum alloys can be produced according to customer needs. This alloy has been used in "non-standard" thermocouples, electrical contacts, and electrodes in medical research. This alloy is harder and mechanically stronger than platinum.
Ptlrl0, Ptlr15, Ptlr25, Ptlr30 and other alloys have the characteristics of high hardness, high melting point, high corrosion resistance and low contact resistance. The chemical corrosion rate is 58% of that of pure platinum, and the oxidation weight loss is 2.8 mg/g.
