===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 <xr id="tab:Mechanical Properties of Tungsten and MolybdenumMechanical_Properties_of_Tungsten_and_Molybdenum"/> (Table 2.35). 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 components in composite materials with silver and copper.
