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.

China Heat Sink Inc. specializes in producing aluminum heatsinks for various applications. We use advanced technology and high-quality materials to make heatsinks that meet the specific requirements of our customers. We have a team of skilled engineers who can design and develop custom heatsinks that meet clients’ unique needs.

THE MOST WIDELY USED HEATSINK MATERIAL

An Aluminum heatsink is the most widely used product for thermal solutions. Aluminum (Aluminum) 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 aluminum 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 China Heat Sink Inc. 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.
