Tungsten alloy contacts Features:

1.Double composite riveting efficiently save precious metals and reduce the cost;

2.Trimetal rivet can replace solid rivets. It widely used as moving contacts during two sides of contact, to a great extent reduce the wolfram contacts materials cost;

3.Improve the contact rivet riveting performance;

4.tungsten alloy contacts can be applied in continuous automation production.


Application :

1.Relays, Contactors, Micro Switches, Button Switches, Wall Switches, etc.

2.Tungsten and contact points are widely used in automobile electric appliances ,household appliances ,relays ,contactors ,thermostat ,all kinds of switch ,aviation appliances ,timer and electronic appliances.

Various welded wolfram contacts can be produced according to customer's requirement.
