Platinum Iridium

Platinum-iridium is an alloy of the platinum group precious metals platinum and iridium.

Surepure Chemetals typically supplies alloy proportions of 90% platinum / 10% iridium and 80% platinum / 20% iridium. Surepure Chemetals sells platinum-iridium conforming to the ASTM B684 specification (including ASTM B 684-97).

These have the chemical stability of platinum, but increased hardness.

Due to its high density, hardness, and resistance to corrosion, platinum-iridium was used to make the international prototype kilogram and the international prototype meter.

One use for Pt/Ir alloy is fabrication of metal microelectrodes for electrical stimulation of nervous tissue and electrophysiological recordings. Pure iridium is very difficult to pull into small diameter wires, while pure platinum has a low Young's modulus which makes pure platinum wires bend easily during the insertion in nervous tissue; hence Pt/Ir alloy has an optimal combination of mechanical and electrochemical properties for this application.

Surepure Chemetals sells platinum iridium wire and platinum iridium sheet.

Surepure accepts Apple Pay, PayPal, MasterCard, Visa, Discover, and American Express.
