    Ultra-High-Temperature Molybdenum Wire

    Image of Product. Front orientation. Molybdenum. Ultra-High-Temperature Molybdenum Wire, Spool.

    Spool

    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.
