Product Details
Place of Origin: | Zhejiang, China | Brand Name: | LT | Type: | High Voltage |
Application: | Power Station | Conductor Material: | Copper |
Product Description
Tungsten-Copper(Silver)
Features
W-Cu(Ag)products of various specification and shapes with a wide range of copper (silver) content can be produced alternatively by press-sintering, direct infiltration, infiltrating copper(silver) into high temperature sintered or activated sintered skeleton based on applications. The composites such produced are of high purity and homogeneous microstructure with superior performances as follows:
1. Excellent arc erosion resistant and anti-fusion ability.
2. Good electric and heat conductivity.
3. Low thermal expansion coefficient, matching with semiconductor, ceramics and Kovar alloys.
4. Easy matching.
5. Big gravity, high strength, high-temperature resistant and perspiration cooling characteristics.
Applications
Electrical Applications Include:
High Voltage Arc Contacts. (contacts for SF6 Circuit Breaker, electrodes for-surge absorber etc.)
Vacuum Contacts. (for vacuum contactors or vacuum load switches)
Electrodes for Resistance Welding and Spark Erosion.
Leaders for steel Rolling.
Dies for Casting.
Balance Weights.
Rocker Parts.
Electronic Applications Include:
Heal Sinks and Spreaders: Microwave Carriers, Hermetic Package, Ceramic Substrate, Carriers, GaAs and Silicon Device Mounts, Laser Diode Mounts.
