Molybdenum is one of the many refractory metals we use to make precision machined parts. Molybdenum, also known as moly, has a high melting temperature of 2620 deg C. It retains tensile strength at temperatures above 1000 deg C, exhibits a low coefficient of thermal expansion, and good electrical conductivity properties favorable to creating molybdenum components and assemblies for the electronic, semiconductor, and lighting industries. The lighting industry has long favored molybdenum for its ability to retain a glass-to-metal seal very similar to tungsten.
