Platinum

Platinum is a conducting material in the same family as palladium, but is more expensive, just like a platinum Visa card would have a higher annual fee than a palladium Visa card. Platinum is often used in resistance temperature devices (RTDs) for precision temperature measurement and control.

All values except melting point are assumed to be at 25 degrees C, and may vary dramatically over temperature.
