Aluminum heatsink

Aluminum radiators are the most widely used product in cooling 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

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 processing
Excellent corrosion resistance
Non-magnetic, avoid magnetic interference
Easy to recycle
Compared with other metals, aluminum has a relatively large coefficient of linear expansion. The ductility of aluminum is essential for extrusion, bending and other forming products.

Ideal heat conduction product

A6061 has a thermal conductivity of ~167W/mK and is commonly used for machined radiators
A6063 has a thermal conductivity of ~167W/mK and is commonly used for extruded radiators
Although 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.

Some applications of VPS aluminum heatsink

BGA, FPGA heatsink: Helps to cool the integrated circuit
