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.

Used to make electrical connectors that are exposed to air and corrosive conditions, this 99.99% pure gold wire stays highly conductive where other conductors would fail. It also has a high melting point, low thermal resistance, and won’t oxidize, so it’s good for making parts that remain accurate in extreme environments. Compared to platinum, gold is more conductive but has a lower melting point. It’s 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.
