 Long-term supply of imports of the metal iridium, iridium ingots, rods iridium, iridium belt, Iridium powder, iridium bar, iridium trichloride, iridium tetrachloride, symbol: Ir; Color: Silver; melting point: 2446; Boiling Point: 4428, Iridium Iridium is one of the nature of platinum-group metals, is a refractory metal. Density of 22.40 g / cm 3. Hard and brittle at room temperature, high temperature can be pressed into sheets or drawn into wire. Is only available in oxidizing atmosphere and without serious losses under 2300 ℃ metal. High melting point and hardness than platinum. Iridium chemical stability, it does not with any acid (including aqua regia) work, but by the molten salt corrosion. Iridium nature of similar nature with other metals of platinum, often symbiotic together. By mainly from iron, nickel, copper sulphide and platinum placers of the by-products obtained. The use of Iridium Iridium and its alloys in the petrochemical industry mainly as a catalyst. In electrical and electronic industries, for the manufacture of resistance wire, thermocouple, according to the cathode wire, relays, electrical contacts and printed circuit. Iridium platinum alloy of high hardness gyroscopes used to create conducting ring, pen, watches, instrument bearings. International standard meter rule is to use 10% and 90% iridium alloy made of platinum. High-temperature reaction of iridium crucible can be made, the price below the market price, quality and acceptance by national standards. I am only responsible for the delivery, please contact us.
