Tungsten copper and tungsten silver alloy products
Resistance welding electrodes
Tungsten copper alloy and tungsten alloy have high thermal endurance and good conductivity, and are usually used as resistance welding electrodes
Machining EDM electrodes
The high electric corrosion rate, low loss rate and high electrical conductivity of tungsten copper alloy ensure that the accuracy of the workpiece is greatly improved.
Cooling Material
Good thermal conductivity and high heat resistance allow tungsten to be used as a cooling material within a certain high temperature range.
Counterweight Blocks
Due to its high density, tungsten has the smallest volume under the same weight, making it an ideal material for counterweight blocks. Depending on the application, it can be processed into vibrating or non-vibrating materials.
Power Contacts
High heat resistance and electrical conductivity determine the application of power contacts. At the same time, tungsten can also prevent the harm caused by electric shock.
Uses of tungsten copper alloy:
High performance materials for aerospace. Tungsten copper material has high density, perspiration cooling performance, high high temperature strength and resistance to erosion and ablation. It is used in the aerospace industry, rockets, etc. Bomb nozzle throat lining, gas rudder components, air rudder, head cover and counterweight, etc. , Vacuum contact material The contact material must have very good machining performance and thermal shock resistance. Due to arcing during contact and breaking, the temperature of the contact material will rise by thousands of degrees Celsius in a few tenths of a second. The contact materials produced by our company are widely used due to their excellent physical properties. Advantages: high ablation resistance, high toughness, good electrical and thermal conductivity. Good machining performance.
Electrodes for EDM When machining cemented carbide products with EDM, copper or graphite electrodes wear out very quickly due to their special properties. For EDM machining of this material, the electrodes produced by our company are Most suitable. Product performance: high electrical corrosion rate, low loss rate, precise electrode shape, excellent processing performance, and good surface quality of the workpiece. Product types: rods, plates
, electronic packaging materials 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 and electrical conductivity can be adjusted It is designed based on the composition of the material, thus bringing great convenience to the application of the material. We use high-purity, high-quality raw materials, and after compression molding, high-temperature sintering and infiltration, we obtain electronic packaging materials and heat sink materials with excellent performance. Materials suitable for packaging high-power devices, such as substrates, lower electrodes and other high-performance lead frames, and thermal control boards and radiators of civilian thermal control devices. Advantages: Thermal expansion coefficient and high thermal conductivity matching different substrates, excellent high temperature stability and uniformity, excellent processing performance
Precautions about tungsten copper [Precautions for using tungsten copper] Please confirm when opening the package The product has no defects, cracks or other abnormalities. The specific gravity of tungsten copper is larger than that of steel products. Please pay full attention when using it to prevent the product from falling and injuring your hands or feet. [Notes on product shape] The appearance of tungsten copper products after milling machine shaping, lathe shaping processing, and grinding machine processing is normal. [Tungsten Copper Processing Precautions]. When cutting tungsten copper alloy to make thin walls with sharp corners, defects may occur due to impact or excessive processing load. When drilling through-holes for tungsten-copper alloy products, please pay attention to the feed load when the hole is about to be drilled to avoid processing defects. Tungsten copper alloy is non-magnetic. Customers are kindly asked to confirm that the product is firmly fixed before operation. .The discharge and wire cutting speed of tungsten copper products during electrical discharge processing and wire cutting are relatively slow, which is a normal phenomenon. [Notes on Tungsten Copper Electroplating] Tungsten copper alloy is a metal powder crystal. Please avoid strong acid and strong alkali cleaning before electroplating to avoid surface metal particles falling off and affecting the electroplating effect
