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.

While in some cases it may be considered advantageous to use precision machined pure tungsten, molybdenum has better machinability when compared to tungsten.  Sylhan has significant experience working with molybdenum machined parts.  Because of the ability to be easily machined, pure molybdenum gained widespread acceptance for use as ion implantation arc chambers and heat sources in the ion implantation process, and use in molecular beam epitaxy and MOCVD devices.  It is also used in sputtering targets and backing plates for sputtering (see PVD sputtering process for more information).
