Tungsten and Molybdenumsilvertungsten Siwodur Materialssilvertungsten Carbide Siwodur C MaterialsSilverMolybdenum Silmodur MaterialsCopperTungsten Cuwodur MaterialsTungsten is characterized by its advantageous properties of high melting and boiling points, sufficient electrical and thermal conductivity and high hardness and density Table 1. 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 used in large amounts as componen
