Iridium element applications : Many high melting point oxide single crystals are grown in crucibles made of pure iridium. Pure iridium, platinum iridium alloy, and iridium rhodium alloy are mostly used for making scientific instruments, thermocouples, resistance wires, etc. Adding iridium to platinum can improve the corrosion resistance of platinum in water, acid and halogen, as well as the mechanical strength below 500 ° C. However, as the iridium content increases, the weight loss of the alloy above 900 ° C in air is weightless. Also increased.  A platinum-iridium alloy containing 10% iridium and 90% platinum has a very small expansion coefficient and is used to make international standard rulers. The kilogram original parts in the world were also made of platinum-iridium alloy.

Iridium is a rare and precious metal. It is an alloy of platinum and iridium, which is rarer than platinum. Its melting point, strength and hardness are all very high. The color is silver-white, with strong metallic luster, and hardness 7. The relative density is 22.40, but it is brittle , can be pressed into foils or drawn into filaments at high temperatures. Chemically very stable, insoluble in aqua regia. Mainly used in the manufacture of scientific instruments, thermocouples, resistors, etc. High-hardness iron-iridium and iridium-platinum alloys are commonly used to make nibs and platinum jewelry. Due to its extremely high melting point and super corrosion resistance, iridium is widely used in high-level technical fields, such as aerospace technology, pharmaceutical and automotive industries.
