Product Description

Product Description

- These Stud electrodes are made from RWMA Class 2 material with 10W (copper tungsten) on the weld face for longer life. The part has wrench flats for easy removal from holders.The insulator is made to withstand the constant friction that is applied as the stud is inserted and removed. 

- Tungsten copper parts have a ground finish and is manufactured by pressing and sintering, products vary from Copper Tungsten Electrical
Contacts,Copper Tungsten Electrode, WCu Rod, Electrode For PCD Grinding WCu. 
- We offer: 65%W-35%Cu, 70%W-30%Cu, 75%W-25%Cu ,80%W-20%Cu material
- Our standard: accordance with ASTM B702

Company Profile

 Xi'an Kefeng Powder Metallurgy is a professional China copper tungsten electrical contacts manufacturer.  We produce Copper Tungsten contacts
ccording to the customer's drawings and all copper tungsten products conform to ASTM B702, shapes are rods, bars, plates, blocks and other different specifications parts. 

High voltage discharge tube electrode: During the operation of the high voltage vacuum discharge tube, the contact material will experience a temperature increase of several thousand degrees Celsius in just a few seconds. The high resistance to ablation, high toughness, and good conductivity and thermal conductivity of tungsten copper provide necessary conditions for the stable operation of discharge tubes.
4. Electronic packaging materials: They have both the low expansion properties of tungsten and the high thermal conductivity properties of copper, and their thermal expansion coefficient and conductivity can be changed by adjusting the composition of the material.

Characteristics and features

1. Low thermal expansion
2. High wear resistance
3. Low consumption
4. High arc resistance
5. High thermal and electrical conductivity
