Tungsten points Material - I

Tungsten points, also known as tungsten electrical points or tungsten contacts, which are used in equipment, instruments and switching equipment as a contact part. They are playing a role in turning on and turning off the current. Thus, tungsten points will influence the properties of the switching devices directly when they are in running state. People began to use contact materials about a hundred years ago, which started with pure silver, pure gold and pure platinum and other contact materials. People began to use alloy materials until the 1940s, such as, gold silver, platinum indium and silver copper materials. People gradually found composite materials of precious metal after the 1960s. People gradually turn their attention to tungsten materials since tungsten was found in 1781.

Tungsten contact materials possess high purity, high melting point (up to 3422 ° C), high density, high hardness, nice wear resistance, good corrosion resistance, low conductivity and other properties.

Properties of silver material are: silver owns excellent processing performance, the best thermal conductivity and high antioxidant capacity and other properties in all metals.
