Ultra High-Temperature Molybdenum Wire

Spool

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.

Tantalum Wire

Spool

Hardness: Rockwell C69 (Ultra Hard)

Harder than platinum and able to withstand higher temperatures than gold, this 99.98% pure tantalum wire also resists corrosion and conducts heat. It’s often used in heating elements for furnaces.

Platinum Wire

Hardness: Rockwell B97 (Medium)

99.95% pure, this platinum wire is used for applications that require a soft material that resists corrosion and oxidation and has a high melting point. This wire allows heat and electricity to pass and resists oxide buildup, making it ideal for thermocouple probes, which require accurate readings even at high temperatures. Soft enough to create a good seal between two flanges, it's also used to make high-vacuum O-rings. Platinum's softness means it won't damage the flanges, so they can be used again. The high melting point of this wire makes it a better choice for sealing heated flanges than other materials such as gold.
