Characteristic




Platinum-iridium alloys are alloys of the platinum group precious metals platinum and iridium.




Typical alloy proportions are 90:10 or 70:30 (Pt:Ir). These have the chemical stability of platinum, but increased hardness. The Vickers hardness of pure platinum is 56 HV while platinum with 50% of iridium can reach over 500 HV.




Chemical formula: PtIr

Molecular Weight:387.3g/mol

Appearance:Metallic solid in various forms (wire, bar, sheet, powder) 

Solubility in water:Insoluble
