Why Use an Aluminum Heatsink?

Aluminum heatsinks are essential in electronic devices that require cooling to prevent overheating and damage. As such, the demand for aluminum heatsinks has been steadily increasing over the years.

Choosing a suitable aluminum heatsink manufacturer is critical to ensure the performance and reliability of your electronic devices. When choosing a manufacturer, it is essential to consider factors such as quality, experience, customization, cost, and delivery time.

Radian Thermal Products specializes in producing aluminum heatsinks for various applications. We are a team of skilled engineers using advanced technologies and high-quality materials to design and manufacture heatsinks that meet our customer’s specific requirements.

The Most Widely Used Heatsink Material

Aluminum is the most widey used material for heatsink design due to the following properties:

Good thermal conductivity
Lightweight with a density ~ 2,700 kg/m³
Low weight
High strength between 70 to 700 MPa
Easy to extrude
Easy to machine
Excellent corrosion resistance
Non-ferrous to avoid interference with 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 ~177 W/(mK) and is typically used formachined heatsinks
A6063 has a thermal conductivity of ~210 W/(mK) and is typically used forextruded heatsinks

Although the thermal conductivity of aluminum is approximately half that of copper, a copper heatsink is approximately three times heavier than an equivalent aluminum heatsink. Aluminum is also less expensive than copper.

Although aluminum is naturally resistant to corrosion, all Radian heatsinks are anodized as part of the finishing process. This forms a thicker protective layer that increases corrosion resistance while also improving the surface finish.

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.

Ball Grid Array (BGA) Plate Fin Aluminum Heatsink

Radian has a wide range of BGA Plate Fin Aluminum Heatsinks that are available to ship within a few days. If a part or 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.
