MoCu15 Molybdenum Copper Alloy Machining Parts For Heat Sink Material
1. MoCu15 Molybdenum Copper Alloy Machining Parts For Heat Sink Material Specifications:
The excellent thermal conductivity of molybdenum copper alloy makes it a suitable material for use as a heat sink. The properties of these two alloys are similar, and the density of molybdenum copper alloy is lower than that of tungsten copper alloy. The preparation of molybdenum copper alloy is mainly by dipping method, using high quality molybdenum powder and oxygen free copper powder, and applying isostatic pressing (high temperature sintering copper infiltration), with fine structure, good arc breaking performance, good electrical conductivity and thermal conductivity. Well, there is little thermal expansion.
2. Basic parameters of MoCu15 Molybdenum Copper Alloy Machining Parts For Heat Sink Material:
| Grade | Mo content % | Cu content % | Density (g/cm3) | Thermal conductivity (W/M.K) | Thermal expansion coefficient (10-6/K) |
| Mo85Cu15 | 85±1 | Balance | 10 | 160~180 | 6.8 |
| Mo80Cu20 | 80±1 | Balance | 9.9 | 170~190 | 7.7 |
| Mo70Cu30 | 70±1 | Balance | 9.8 | 180~200 | 9.1 |
| Mo60Cu40 | 60±1 | Balance | 9.66 | 210~250 | 10.3 |
| Mo50Cu50 | 50±1 | Balance | 9.54 | 230~270 | 11.5 |
| Mo40Cu60 | 40±1 | Balance | 9.43 | 280~290 | 11.8 |
3. Feature of MoCu15 Molybdenum Copper Alloy Machining Parts For Heat Sink Material:
1). Molybdenum copper alloys for electronic packaging (heat sinks),
similar to tungsten copper alloys, also have compositional
tunability, resulting in adjustable thermal conductivity and
thermal expansion coefficient.
2). Compared with tungsten copper alloy, molybdenum copper alloy
has lower density but larger thermal expansion coefficient.
3). Heat is produced in large quantities while power electronics
and circuits are in use. The heat sink material helps to dissipate
heat from the chip, transfer it to other media, and maintain stable
operation of the chip.
4). It has the thermal expansion coefficient and high thermal
conductivity matching with different substrates; excellent high
temperature stability and uniformity; excellent processing
performance.
5). Molybdenum copper alloy is a pseudo-alloy composed of two
insoluble metals, molybdenum and copper. It has both the
characteristics of molybdenum and copper, and has high thermal
conductivity, low thermal expansion coefficient, non-magnetic, low
gas content, good Vacuum properties, good machinability and special
high temperature properties.
6). Compared with tungsten-copper, molybdenum copper alloy has
lower density and can be stamped, suitable for super-large batches.
