2017 New Style Automotive Parts - Copper Tungsten – De-Shin Detail:
Ningbo De-Shin offers a full range of copper tungsten(6~50wt.% Cu) for different industrial application fields. It takes the advanced vacuum infiltration process and all products meet the criterion of GB/T 8320-2003, ASTM B 702-93(Reapproved 2004). Copper tungsten is pseudo-alloy and it holds the wear resistance capability of tungsten and high electrical conductivity of copper.
Production process: powder mix –> press –> sintering –> vacuum infiltration –> machining –> QC. All this production process is strictly controlled by QC to ensure best quality performance.
Advantages:
1. High arc resistance combined with good electrical conductivity.
2. High thermal conductivity.
3. Low thermal expansion.
Applications:
1. Arcing contacts and vaccum contacts in high and medium voltage breakers or vaccum interruptors.
2. Electrodes in electric spark erosion cutting machines.
3. Product Demo! Heat sinks as passive cooling elements of electronic devices and Electronic packaging materials.
4. Electrodes for resistance welding.
Stock size:
Copper tungsten rod: diameter≥0.5mm; length≤300mm.
Copper tungsten plate: thickness≥1.0mm; length & width≤300mm.
