Gold has a bright, reddish-yellow color in its purest form. It does not oxidize in the air at room temperature, so it remains very stable under normal conditions and its electrical conductivity is constant. It is one of the most common precious metals used in finishing.
Gold is corrosion resistant, which makes it a good finish for connector pins and electrical switch contacts.
Gold plating is used in parts and components across a wide range of industries including medical, energy, semiconductor, aerospace & defense, telecommunications, and oil & gas industries.
