iridium ,a precious metal,has an appearance similar to platinum in that it is white,but with a slightly yellowish tint.it is the most corrosion-resistant metal known,is very hard,brittle,and has a low ductility,making it difficult to machine,form,or work.its principle use is as a hardening agent for platinum,though it is frequently found in crucibles and other high temperature devices. iridium powder purity 99.95 pourcent appearance powder color grey - black density 22.65g/cm3 melting point 2450 °c boiling point 4428°c vickers hardness 500 inner packing by vacuum bag outter packing by vacuum bag,1000g/bag, 100oz/bag min trial order 100grams applications 1.used as a hardening agent in alloys with platinum and osmium. 2.used for crucibles highly resistant to corrosion , special containers and other apparatus resistant to intense heat. 3.alloyed with platinum to make heavy duty electrical contacts such as high performance technically advanced spark plugs for use in the automotive and aviation industries. 4.as a catalyst to produce organic acids e.g. ethanoic acid . 5.iridium alloyed with osmium is used to tip fountain pen nibs and in pivot bearings such as those found in compasses, surgical tools and other special equipment. 6.apply to electrical instrumentation, chemical industry and production of precision alloy. welcome to contact us.
