Tungsten copper integral contact, rivet type integral tungsten copper contact
The manufacturing method of rivet type tungsten copper and silver tungsten all contacts is to make tungsten copper and copper materials at one time, and then the material is formed by mechanical manufacturing. Advantages and features l the bonding part of tungsten copper material and copper material does not use any flux and solder to ensure that the touch resistance of rivet type electrical contact is minimized. L the tungsten copper material and copper material are fully blended, and the copper element in the tungsten copper alloy is integrated with the copper element in the copper material, so as to ensure that the contact will not fall from the tungsten copper material and copper matrix due to high temperature during operation. It is safe and reliable. L the touch surface can select tungsten copper alloy, silver tungsten alloy, tungsten copper carbide and silver tungsten carbide according to the actual needs of customers. We can select different contents of tungsten copper alloy, silver tungsten alloy, tungsten carbide copper and silver tungsten carbide alloy materials according to the actual needs of customers. The tungsten content of our company can be freely distributed between 30% and 90% to meet the needs of customers in different environments. It has the characteristics of anti fusion welding, good electrical wear resistance, short arc time, high breaking function and strong resistance to high current impact. Under the condition of large breaking current, it has more ideal ability to resist arc corrosion. Under the condition of high touch pressure, it has higher mechanical wear resistance than silver based contact. L environmental protection, non-toxic, in line with the EU Rosh environmental requirements. L the thermal expansion coefficient of touch surface material is small, which can prevent the increase of touch resistance caused by the increase of thermal expansion and cold contraction difference of contact material, and prevent thermal wear.
