Aluminum heatsinks are the most widely used product in cooling solutions.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.

Advantages of VPS aluminum heatsink

Good thermal and electrical conductivity
Low density: ~ 2,700 kg/m3

Light weight

High strength from 70 to 700 MPa

Malleable

Easy to process

Excellent corrosion resistance

Non-magnetic, thus can avoid magnetic interference

Easy to recycle

Compared with other metals, aluminum has a relatively large coefficient of linear thermal expansion. The malleability of aluminum is essential for extrusion, bending and other shaped products

Ideal thermal conductive product

A6061 has a thermal conductivity of ~167W/m-K and is commonly used for processing heatsink.

A6063 has a thermal conductivity of ~167W/m-K and is commonly used for extrusion heatsink.

Although its thermal properties are inferior to copper, an aluminum heatsink weighs approximately half as much as a copper heat sink with the same electrical conductivity and is also cheaper.

Aluminum reacts with oxygen in the 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 protective layer against corrosion.
