Application
Tungsten-copper alloy is a two-phase structure pseudo-alloy based on the chair element table and the copper element table as a sub-composition. It is a composite material in the whole genus. Due to the large difference in the physical properties of metal tungsten and its structure, it cannot be produced by the melting and casting method, and now it is generally produced by the powder combining technology. Tungsten alloy powder metallurgy sintered parts all-composite material (commonly known as tungsten-tungsten or tungsten-tungsten) is composed of tungsten with high melting point, high hardness and copper with high electrical conductivity and high thermal conductivity, so it has good resistance to arc burning. It is widely used as electrical contact material for vacuum and other high-voltage switches, electrode material for resistance welding and EDM, electronic packaging material, electronic assembly heat sink substrate materials, radiation shielding materials, high-density counterweight materials, etc.
Tungsten copper alloy applications include:
1. High-performance materials for aerospace: tungsten-copper materials have high density, perspiration cooling performance, high high temperature strength, and erosion and ablation resistance.
2. Vacuum contact material: The tungsten copper/copper composite contact does not conform to the third alloy element table. The tungsten substrate is sintered at a high temperature of above 2000C, and the whole is subjected to high vacuum treatment. It has uniform material, low gas and impurity content, high electrical conductivity, It has the advantages of good composite interface and dense copper layer.
Advantages: high ablation resistance, high toughness, good electrical and thermal conductivity. Good machining performance.
Delivery status: W-Cu contacts of various shapes connected with copper, steel and other supports,
Semi-finished products: various unprocessed infiltration and casting materials; various unprocessed contacts, welded or donated to support parts such as copper and steel; welding or copper welding processing.
3. Electrode for EDM: When using EDM to process cemented carbide products, copper or graphite electrodes wear out very quickly due to the special properties of WC. For EDM of this material, Tongxiang's W-Cu electrodes are the most suitable,
Product performance: high electrical corrosion rate, low loss rate, precise electrode shape, excellent processing performance, and good surface quality of WC.
4. Electronic packaging materials and heat sink materials: W-Cu electronic packaging materials have both the low expansion properties of tungsten and the high thermal conductivity properties of copper. What is particularly valuable is that its thermal expansion coefficient and thermal conductivity can be adjusted by adjusting the material. We use high-purity high-quality raw materials, and after pressing, high-temperature sintering and infiltration, we obtain W-Cu electronic packaging materials and thermal sink material. Materials suitable for packaging with high-power devices, such as substrates, electrodes, etc.; high-performance lead frames; thermal control boards and heat sinks for military and civilian thermal control devices.
Advantages: It has a thermal film coefficient and high thermal conductivity matching with different substrates; excellent high temperature stability and uniformity; excellent processing performance;
Product Specifications: The surface is electrically connected to Ni, NiAu or electroless NiW-Cu plate, the maximum size is 100x100mm, and the thickness is 0.5-50mm.
