1) High-performance materials for aviation
With properties of high density, sweat cooling, high high-temperature strength, erosion-ablation resistance, etc., the tungsten copper material can be used as nozzle throats of missiles and rockets, components of gas vanes, air vanes, head coverings and balancing weights in the aerospace industry.
2) Vacuum Contact Materials
The contact material must have very good machining property and thermal shock resistance; Because arc strike occurs during contacting and breaking, the temperature of the contact material will rise to several thousand Celsius degrees within less than one second. The W-Cu contact materials produced by our company are widely used due to its excellent physical performance.
Advantages: High anti-ablation performance, high toughness, good electric and thermal conductivity, and good machining property.
Delivery state: W-Cu contacts of various shapes in good connection with copper or steel supports
Semi-finished products: Various unmachined infiltration and forging materials; Various unmachined contacts welded or copper welded on copper or steel supports; And welding or copper welding machining.
Our company also manufactures contact connecting pieces for welding or copper welding.
3) Circuit for Electric Spark Machining
When the electric spark is used to machine hard alloy products, the consumption of copper or graphite electrodes is too fast due to special performances of WC, and the W-Cu electrode manufactured by our company is best suitable for the electric spark machining of the materials, Product performance: High electric corrosion speed, low attrition rate, accurate electrode shape, excellent machining property, and good quality of WC surfaces of machined pieces.
Product Types: Rods, pipes and plates
4) Electric Packaging Material
The W-Cu electric packaging material has both low swelling property of tungsten and high thermal conductivity of copper, more importantly, its thermal-expansion coefficient and thermal-electric conductivity can be designed by adjusting compositions of the material, so that extreme convenience in application is brought to the material.
Made of highly purified good-quality raw materials, W-Cu electric packaging materials and heat sink materials with excellent in performance are obtained through compression forming, high-temperature sintering and infiltration. The W-Cu electric packaging material is applied to materials packaged with high-power devices such as substrates and lower electrodes, high-performance leading wire frame, and thermal control plates and radiators of thermal control devices for military and civil use.
Advantages: Thermal-expansion coefficients matched with different substrates and the high thermal conductivity; Excellent high-temperature stability and uniformity; And excellent machining property.
Product Specification: Surface electroplating Ni, NiAu or electroless plating Ni W-Cu plate, maximum size of 100*100mm, and thickness of 0.5 to 50mm.
