products of various specification and shapes with a wide range of copper content can be produced alternatively by press-sintering, direct infiltration, infiltrating copperinto 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.
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.
Electronic Applications Include:
Heal Sinks and Spreaders: Microwave Carriers, Hermetic Package, Ceramic Substrate, Carriers, GaAs and Silicon Device Mounts, Laser Diode Mounts.
