Tungsten Copper Alloy Electronic Packaging Materials And Heat Sink
The Tungsten Copper Alloy Electronic Packaging Materials And Heat Sink material is a composite material of tungsten and copper. It has both the low expansion characteristics of tungsten and the high thermal conductivity of copper. The thermal expansion coefficient and thermal conductivity of tungsten and copper can be adjusted with the composition of W-Cu. The material can also be processed into various shapes

The difference between tungsten copper alloy and molybdenum copper
alloy?
Also as alloy materials, tungsten-copper alloy and
molybdenum-copper alloy are used in a wide range of applications,
such as aerospace, aviation, navigation, military, defense,
electronics, electric power, metallurgy, machinery, sports
equipment and other industries. In the same application field,
although they can be replaced with each other in some cases, there
are many differences.
1. Different definitions
Tungsten copper alloy is an alloy material composed of tungsten
atoms and copper atoms. The English name is copper tungsten or
tungsten copper. The copper content is 10%-50%, and the tungsten
content is 30%-95%.
Molybdenum-copper alloy is an alloy material composed of molybdenum
atoms and copper atoms. It is called molybdenum-copper alloy in
English. It can replace the application of tungsten-copper alloy in
many cases. According to the different chemical composition, the
grades of molybdenum copper alloy can be divided into MoCu10,
MoCu15, MoCu20, MoCu25, MoCu40, and their total impurity content is
less than 0.1%.
2. Different in nature
Tungsten copper alloy 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
Tungsten copper alloy 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.
