An Aluminum heat sink is the most widely used product for thermal solutions. Aluminum (Aluminium) is the second most widely used metal in the world after Iron. After oxygen and silicon, aluminum is the most common element in the Earth’s crust. The properties that make a aluminium heat sink popular include:
Good thermal and electrical conductivity
Low density with a density ~ 2,700 kg/m3
High strength of between 70 and 700 MPa
Excellent corrosion resistance
non-magnetic which avoids interference of magnetic fields
Easy to recycle
Compared with other metals, aluminum has a relatively large coefficient of linear expansion. Aluminum’s malleability is essential for the extrusion process, and in bending and other forming products.
An Aluminum heat sink is an excellent conductor of heat.
A6061 has a thermal conductivity of ~ 167W/m-K and is typically used for machined heat sinks
A6063 has a thermal conductivity of ~ 167W/m-K and is typically used for extruded heat sinks
Although the thermal properties are less than copper, An aluminum heat sink weighs approximately half as much as a copper conductor having the same conductivity, and is also better price.
Aluminum reacts with oxygen in air to form an extremely thin layer of Aluminum Oxide. Anodizing increases the thickness of the oxide layer and improves the strength of the natural corrosion protection. We can also make other surface treatment as your requirement.
Heat sinks help absorb and dissipate the heat generated by electronic devices. You need to be sure you choose the appropriate type based on your design needs and volume requirements.
Remember that sometimes active heat sinks are required for enhanced heat dissipation. But passive heat sinks with no moving parts can be used as well.
Also, when it comes to materials, aluminum offers weight and cost savings, while copper allows the highest level of thermal conductivity.
From extrusion and bonding to forging and machining, there are a number of different manufacturing options available. Each has its advantages and drawbacks.
If aluminum extrusion or CNC machining happen to fit your needs, we can help.
The precision aluminum profile tolerance can reach ±0.02MM.
CNC precision machining is a subtracted manufacturing method that uses cutting tools to remove material from raw material locks or pre-existing parts.
Our company can customize according to your demand, like mechanical parts processing, CNC aluminum products processing, CNC aluminum processing, CNC precision machining, CNC processing customization and etc . Then mass production of samples and rapid production of samples. We guarantee high quality and high precision .
