Platinum Wire

Spool

Hardness: Rockwell B97 (Medium)

Use this 99.95% pure platinum wire to create thermocouple probes and other parts that maintain high accuracy in extreme conditions. It won’t oxidize, won’t corrode in most settings, and has low thermal and electrical resistance. Platinum is often used to make O-rings, even for high-vacuum applications, because it’s soft enough to form a good seal when pressed between two flanges, yet won’t damage the flanges so you can reuse them. It’s also useful with high temperatures since it has a higher melting point than other sealing materials, such as gold.
