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.
