Iridium, metal element, element symbol Ir, atomic number 77, atomic weight 192.22, the element name comes from Latin, the original meaning is "rainbow". The content of iridium in the earth's crust is one in ten million, and it is often dispersed in various ores of alluvial deposits and placer deposits together with platinum elements. Excellent iridium ingot suppliers explain the use of iridium ingots for you.

Most of the applications of iridium ingots use its high melting point, high hardness and corrosion resistance properties. Iridium metal, as well as iridium-platinum alloys and osmium-iridium alloys, have very low losses and can be used to make porous spinnerets. Spinnerets are used to extrude plastic polymers into fibers, such as rayon. Osmium-iridium alloys can also be used in compass bearings and weighing scales.

Iridium ingots are also often used in instruments that have to withstand high temperatures. For example, the Tchaikolaski process uses high-temperature crucibles made of iridium to produce individual oxide crystals such as sapphire, gadolinium gallium garnet, and yttrium aluminum garnet. These crystals are used in computer memory and solid-state laser parts. Iridium alloys resist arc erosion, making them ideal for spark plug electrical contacts.
