Higher Density CuW Alloy Copper Tungsten Bar / Sheets / Rods
Copper Tungsten Bar is an alloy material composed of tungsten atoms and copper atoms. It is called Tungsten-copper alloy in English. It can replace the application of molybdenum copper alloy in many cases.
Copper Tungsten Bar has both the characteristics of tungsten and copper, and has good electrical and thermal conductivity, corrosion resistance, wear resistance and processing performance. When the temperature is above 3000 ℃, the copper in the alloy will be liquefied and evaporated. Compared with tungsten copper, molybdenum copper has lower density and lighter weight, and is more suitable for use in some products with stricter requirements on weight indicators.
Molybdenum copper alloy has the characteristics of both molybdenum and copper, and has the characteristics of non-magnetic, strong high temperature resistance, high thermal conductivity, low adjustable thermal expansion coefficient, excellent vacuum performance and mechanical processability. In terms of heat resistance and wetting, molybdenum copper is worse than tungsten copper.
Three, the production process is different
The preparation methods of tungsten copper alloy include powder metallurgy method, injection molding method, copper oxide powder method, tungsten skeleton infiltration method and so on. Among them, the powder metallurgy process to prepare tungsten copper alloy is powder-making-batching mixing-pressing forming-sintering infiltration-cold working.
The preparation methods of molybdenum copper alloy include liquid phase sintering method and molybdenum skeleton infiltration method. The liquid phase sintering method refers to the liquid phase sintering of the molybdenum-copper mixed powder at a temperature of 1300-1500°C after being pressed into a shape.
Four, different uses
Copper Tungsten Bar is mainly used in high temperature resistant materials, electrical machining electrodes, microelectronic materials, electrical alloys for high voltage switches, etc.
Molybdenum copper alloy is suitable for manufacturing military and civilian high-power microelectronic devices.
