Platinum Iridium Alloy (Pt:Ir; 80:20 Wt%)-Foil introduce:
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
Appearance:Metallic solid in various forms (wire, bar, sheet, powder)
Solubility in water:Insoluble
