Platinum/Iridium Alloy Foil (Pt90/Ir10)

Platinum/Iridium Alloy Foil (Pt90/Ir10) is a metallic foil from Goodfellow's range of precious metal alloys. The high temperature resistance and corrosion resistance of platinum combined with the strength and hardness of iridium make this alloy useful for high temperature electrical contacts and crucibles for handling corrosive chemicals. This alloy is also commonly used for the tips of spark plugs due to its resistance to electrical erosion. As a high performance foil, Platinum/Iridium Alloy Foil (Pt90/Ir10) enables innovative applications across industries like electronics, aerospace, and chemistry.
