Advantages of Tungsten Copper Alloy
Tailored Properties
The composition can be adjusted for specific requirements, offering versatility.
Combination of Strength and Conductivity
Unique balance of mechanical and thermal/electrical properties, making it suitable for diverse applications.
Durability
Excellent wear and temperature resistance, ensuring long service life.
Part of the mixed powder sintering process copper infiltration method generally has the following two: tungsten copper plates imageCu powder and 0.5% to 2.5% additives (typically nickel powder) - press molding - sintering - copper infiltration.
The process is simple; this method is suitable for manufacturing Cu> 20% tungsten-copper composite. Various methods to the production of tungsten copper materials, copper distribution along the tungsten grain boundaries, the tungsten skeleton strength is not as good as the high-temperature sintering method, as this method of asking too much of raw materials, ingredients, or the product will contain more impurities and gases.
BW powder - +2.5% Cu powder + static acid - was added to the appropriate melt composite adhesive agent (containing 35% polypropylene, 60% paraffin wax, 5% satiric acid) - the cooling granulation injection form - binder removal - heptanes - 3C% / min heating to 500C, 10C/min heating to 900C - transferred to the high-temperature sintering furnace cooling - heating 10C/min to 1030C - to 10C/min heated to 1200-16200C Melting leaching - cooled to room temperature.
The manufacturing process of tungsten copper plates are according to these steps, which owns properties of tungsten and copper.
Use of Tungsten Copper Alloy
Military High-Temperature Resistant Materials
Tungsten copper alloy is used in aerospace and aviation as missiles, rocket engine nozzles, gas rudders, air rudders, and nose cones. The main requirements are high-temperature resistance (3000K~5000K) and high-temperature resistance to airflow. The sweat cooling effect formed by the volatilization of copper at high temperature (copper melting point 1083℃) is mainly used to reduce the surface temperature of tungsten copper and ensure the use under extreme high-temperature conditions.
Electrical Alloy for High Voltage Switch
Tungsten copper alloy is widely used in high-voltage switch 128kV SF6 circuit breaker WCu/CuCr, high-voltage vacuum load switch (12kV 40.5KV 1000A), and lightning arrester. The high-voltage vacuum switch is small in size, easy to maintain, and has a wide range of applications. It can be used in humid, flammable, explosive, and corrosive environments. The main performance requirements are arc ablation resistance, fusion welding resistance, low cut-off current, low air content, and low thermionic emission capability. In addition to the conventional macro performance requirements, porosity and microstructure performance are also required, so special processes must be adopted, requiring complex processes such as vacuum degassing and vacuum infiltration.
Electro-Processing Electrodes
Early EDM electrodes used copper or graphite electrodes, which are cheap but not resistant to ablation and have basically been replaced by tungsten copper electrodes. The advantages of tungsten copper electrodes are high-temperature resistance, high-temperature strength, arc ablation resistance, good electrical and thermal conductivity, and fast heat dissipation. Their applications are concentrated in electric spark electrodes, resistance welding electrodes, and high-voltage discharge tube electrodes.
Microelectronic Materials
Tungsten copper electronic packaging and heat sink materials have both the low expansion characteristics of tungsten and the high thermal conductivity of copper. Its thermal expansion coefficient and thermal conductivity can be changed by adjusting the composition of tungsten copper, thus providing a wider range of applications for tungsten copper.
