===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 ''(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.
