Molybdenum-Copper Alloy Heat Sink For MoCu Substrates In Laser Microwave Ceramic-Metal Packages
1. Information Of MoCu Alloy Heat Sink For MoCu Substrates:
Molybdenum-copper heat sink is a high-performance heat dissipation
material, which is processed by composite processing of
molybdenum-based materials and copper-based materials. Its main
features are high thermal conductivity, good thermal expansion and
excellent corrosion resistance.
2. Size Of MoCu Alloy Heat Sink For MoCu Substrates:
The size of molybdenum copper heat sink can be customized according
to customer requirements. Generally speaking, its thickness is
0.3~5mm, and its length and width can reach more than 200mm.
3.Performance Of MoCu Alloy Heat Sink For MoCu Substrates:
Grade | Mo content Wt% | Density g/cm3 | Thermal conductivity W/m-K | Thermal expansion coefficient ×10-6 | Conductivity IACA% | Hardness HV |
MoCu50 | 50±2 | 9.54 | 250-268 | 11.3 | >55 | 140 |
MoCu40 | 60±2 | 9.62 | 216-248 | 10.1 | >55 | 156 |
MoCu30 | 70±2 | 9.72 | 170-205 | 8.4 | >45 | 172 |
MoCu20 | 80±2 | 9.85 | 160-190 | 7.3 | >40 | 225 |
4. Advantages Of MoCu Alloy Heat Sink For MoCu Substrates:
1). High thermal conductivity: Molybdenum copper heat sink has
excellent thermal conductivity, and its thermal conductivity can
reach more than 160W/mK, which is more than 2.5 times that of
copper materials, so it is very suitable for heat dissipation of
high-power electronic components.
2). Excellent corrosion resistance: molybdenum copper heat sink not
only has excellent thermal conductivity, but also has high
corrosion resistance, and is not easily corroded by corrosive media
such as humid environment, acid, alkali, etc. It can also maintain
its stable performance.
3). Good thermal expansion: Since the linear expansion coefficients
of molybdenum and copper are far different, compound processing is
required when preparing molybdenum-copper heat sinks. The thermal
expansion performance and thermal stress distribution are uniform,
which can effectively prevent heat cracks from occurring in the
heat sink.
5. Production process Of MoCu Alloy Heat Sink For MoCu Substrates:
The production process for preparing molybdenum-copper heat sinks
generally includes steps such as powder metallurgy, hot isostatic
pressing, and sintering. The specific process is as follows:
1). Mix molybdenum powder and copper powder in proportion to make
mixed powder;
2). Put the mixed powder in the shaper, and use high temperature
and high pressure for hot isostatic pressing;
3). After hot isostatic pressing, sintering is carried out to weld
molybdenum and copper;
4). After sintering, finish machining and cutting to make the
required size and shape.
6.Application scope Of MoCu Alloy Heat Sink For MoCu Substrates:
Molybdenum-copper heat sinks are widely used in the heat
dissipation of high-power electronic components and devices. For
example, power devices such as IGBTs, FETs, and ultra-fast diodes
all require heat sinks for heat dissipation. In addition,
molybdenum copper heat sinks are also widely used in aerospace,
national defense, communication equipment, metal packaging and
other fields.
In a word, molybdenum copper heat sink is an excellent heat
dissipation material with high thermal conductivity, excellent
corrosion resistance and good thermal expansion performance, and is
suitable for heat dissipation of various high-power electronic
components and devices.
