Platinum Wire
- 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.

Molybdenum Wire
- Hardness: Rockwell C59 (Very Hard)
Able to handle high melting points and conduct heat and electricity, this 99.95% pure molybdenum wire is often used in lights to create a support for filaments. It resists oxidation and won’t corrode. Molybdenum is better at conducting heat and electricity than tantalum and platinum, which also have high melting points. It is not, however, as corrosion resistant.
