Aluminum Extrusion Heatsink With Anodizing

Nowadays, most of the electronic products need to use aluminum extruded heat sinks. Why to choose aluminum heat sink extrusions? There are some reasons for the situation:

• First of all, in terms of appearance, the material of the aluminum profile is aluminum alloy, so the weight is light, but the malleability is high, it can be exturded the  corresponding shape  according to the requirements of customers;

• Secondly for the corrosion resistance, aluminum heat sink extrusion has the characteristics of corrosion resistance, small deformation, strong fire resistance, and relatively long service life, which can reach 50-100 years;

• Finally, let's talk about oxidation resistance. The aluminum alloy heat sink has been treated by various processes such as anodizing, nickel plating, so the surface is resistant to acid, alkali erosion and air pollution, and can maintain its inherent color and luster for a long time.

  
  

Aluminum heat sink extrusion process

The aluminum extrusion technology is simply to heat the aluminum ingot to a high temperature of about 520~540 °C, and let the aluminum liquid flow through the extrusion die with grooves under high pressure to make the preliminary heat sink embryo, and then the heat sink preliminary embryo is processed. After cutting, ditching, etc., the heat sinks we commonly see are made. The aluminum extrusion technology is easy to implement and the equipment cost is relatively low, which has also made it widely used in the low-end market in the past few years. The commonly used aluminum extrusion material is AL6063, which has good thermal conductivity (about 160~180 w/m.k) and processability.
