Tungsten and Molybdenum Based Materials

Tungsten and Molybdenum (Pure Metals)

Tungsten is characterized by its advantageous properties of high melting and boiling points, sufficient electrical and thermal conductivity and high hardness and density . It is mainly used in the form of brazed contact tips for switching duties that require a rapid switching sequence such as horn contacts for cars and trucks.

Molybdenum has a much lesser importance as a contact material since it is less resistant against oxidation than tungsten.

Both metals are however...
