Product feature :
1. Better heat resistance
2. Better ablate-resistance
3. High densisty
4. High intensity
5. Excellent thermal and elctrical conductivity
6. Easy to be machined
All of our materials are produced by the press, sinter, and infiltrate process. Each manufacturing step, including the basic powder, is closely controlled, monitored, and signed off on by Quality Assurance. After completion, all manufactured lots are checked for conductivity, density, and hardness prior to shipping. This information is recorded and kept on file, and also accompanies the parts or materials when requested.
EDM and ECM
tungsten composites are used worldwide for EDM (Electrical Discharge Machining) and ECM (Electrochemical Machining) electrodes. All material is manufactured by the press, sinter, and infiltrate process. Virgin powders are used, resulting in a consistent homogeneous material giving high and even burning rates. Copper tungsten is used in plunger/sinker applications where intricate definition is required, especially in tungsten carbide.
