Tungsten Copper for Military
Tungsten Copper Alloy for Military
Advantages of high strength high proportion of copper tungsten alloy of copper and tungsten arc ablation resistance / high temperature thermal conductivity properties / processing performance, ease of cutting, and transpiration cooling, its method of making high quality tungsten powder and oxygen-free copper powder, application isostatic pressing - (high-temperature sintering) - copper infiltration, ensure product purity and accurate ratio, organized crime, and performance. Relative to the ordinary copper and copper alloy materials for electrical erosion machining electrode consumption, poor machining accuracy shortcomings, tungsten copper electrode suitable for high hardness materials and sheet electrical discharge machining, high electrical processed products surface finish, high precision, loss low effective conservation of the electrode material to improve the speed of electrical discharge machining, and improve the precision molds, the other can be used as spot welding / welding electrode. Tungsten copper alloy commonly used in high temperature materials, because of its unique advantages, as military rocket engine nozzle throat insert, rudder and other high temperature components.
Tungsten copper alloy in the aerospace used as a missile, rocket engine nozzle vane air rudder, the nose cone, the main requirement is to require high temperature (3000K to 5000K), high temperature airflow flushing capacity, using mainly copper at high temperatures the volatiles formed diaphoretic refrigeration (copper melting point 1083 ° C), to reduce the surface temperature of the copper tungsten, use in high temperature and under extreme conditions.
Order make tungsten copper gasification military supplies, and smooth reduce absorb a lot of heat, reduce the quality of the material surface temperature, it must ensure that the pores of the tungsten skeleton, with good connectivity and good ventilation effect, as well as a low copper content.
