Vietnam aluminum products in the Heatsink industry

Characteristics of aluminum in the heatsink manufacturing industry

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

• High strength from 70 to 700 MPa
• Easy processing
• Excellent anti-corrosion
• 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.
 
A6061 has a thermal conductivity of ~167W/m-K and is commonly used for machined radiators
A6063 has a thermal conductivity of ~167W/m-K and is commonly used for extruded radiators
Although the 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.
