Tungsten Contacts Material - I

Tungsten contacts, also known as tungsten points or tungsten electrical contacts, which are used to act as a contact part, used in instruments, equipment and switching equipment, etc. Their roles are: turn on and interrupt the current. Therefore, tungsten contacts will directly affect the performance of the switching devices that is running state. About a hundred years ago, people started using contact materials, which began with pure gold, pure silver and pure platinum and other contact materials, until about the 1940s, people began using alloy materials, such as, silver copper, gold silver and platinum indium materials. After the 1960s, people gradually found more composite materials of precious metal. Tungsten was found in 1781, since then, people gradually shift their attention to tungsten materials.

Tungsten contact materials have wear-resistance, high density (19.25g / cm3), high melting point (up to 3422 ° C), high purity, high hardness, corrosion resistance, low conductivity and other characteristics.

Characteristics of silver material: in all metals, silver has the best thermal conductivity, excellent processing performance and high antioxidant capacity and so on.
