Platinum Iridium Alloy Wire
Platinum Iridium Alloy Wire
Platinum Iridium Alloy Wire has been used in "non-standard" thermocouples, electrical contacts and electrodes in medical research. This alloy is harder and mechanically stronger than platinum. Iridium is a precious metal that has a similar appearance to platinum in that it is white but has a slightly yellow tinge. It is the most corrosion-resistant metal known, very hard, brittle, and has very low ductility, making it difficult to machine, shape, or work. Platinum-iridium wire has good corrosion resistance and ductility, and has been widely used in the field of electrical contact. The high hardness and low contact resistance of 10% and 20% iridium alloys make them particularly suitable for low current, low voltage applications, where dust contamination can affect the performance of softer materials.
