Aluminum Heatsink

Aluminum heatsinkAn Aluminum heatsink 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 heatsink popular include:

  • Good thermal and electrical conductivity
  • Low density with a density ~ 2,700 kg/m3
  • Low weight
  • High strength of between 70 and 700 MPa
  • Easy malleability
  • Easy machining
  • 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 heatsink is an excellent conductor of heat.

  • A6061 has a thermal conductivity of ~ 167W/m-K and is typically used for machined heatsinks
  • A6063 has a thermal conductivity of ~ 167W/m-K and is typically used for extruded heatsinks

Although the thermal properties are less than copper, An aluminum heatsink weighs approximately half as much as a copper conductor having the same conductivity, and is also less expensive.

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.

 

Radian Aluminum Heatsink product range

An Aluminum heatsink from Radian Thermal Products can be either a standard product, or custom design. For a custom Aluminum heatsink we can offer a design based on thermal requirements or we can manufacture to your design (build to print). We work with a wide range of customers that may need only a few Aluminum heatsinks, or are a production company that need many thousands Aluminum heatsinks a month.

BGA Aluminum PlateFin Heatsinks

INL BGA PlatefinRadian has a wide range of BGA Aluminum Plate Fin Heatsinks that are available to ship within a few days. If a part or BGA heatsink size is not available online we can usually offer an alternative part, or modify a part in stock to fit your needs. For lower volumes, we can also precision machine a heatsink to fit our EZ-snap clip, and for larger volumes an extrusion can be made for your exact requirements.  Please contact us if you need help selecting the correct solution.
