RhPtIr Alloy

Rhodium-Platinum-Iridium (RhPtIr) Alloy

A high-performance alloy combining rhodium, platinum, and iridium for advanced catalytic, electronic, and industrial applications.

The RhPtIr alloy is engineered for extreme conditions where high durability, corrosion resistance, and excellent catalytic activity are crucial. Typically composed of approximately 40% rhodium, 30% platinum, and 30% iridium, it boasts a very high melting point of around 1900°C, very low electrical resistivity, and superior thermal conductivity.
