Copper tungsten alloy sheet electrical contacts switch element price

Tungsten Copper alloy electrical contacts
Brief Introduction: WCu composite materials,
since the 20th century, 30 years since the advent of a long period of time is mainly used for various types of high voltage electrical switch electrical contact.
It is because of the highWCu compositeablative properties of compressive strength and electrical resistance, so that the pressure level of high-voltage electrical switches and the use of power continue to improve and become a high-voltage electrical switches in the indispensable key material.
To 60 years,WCu materialas resistance welding andEDM electrodesand space technology in high-temperature materials exposed to high temperature gas phase are applied.But until the 80's, with theWCu materials, production process improvements and improving the quality ofWCu composite materialthat is to obtain more extensive and sophisticated applications.
90 20th century, with the large scale integrated circuit and the development of high-power electronic devices,WCu materialas the upgrading of the products began to do large-scale use of electronic packaging and heat sink material. Material chemical composition & physical properties:
