  Aluminum alloys are the most popular manufacturing materials on the market today, and the main alloy types  are aluminum alloys 6063 and 6061. Although the heat dissipation performance is not as good as that of copper, the heat dissipation coefficient can reach 201W/mK, which can fully meet the thermal requirements of most of electronic products. In addition, the characteristics of light weight, easy processing, beautiful appearance and affordable price make it widely used.

Why choose aluminum extrusion heat sink?

  Aluminum alloy material has the characteristics of light weight, which is easy to install and transport. When the thermal performance is the same, its weight is only 1/11 of the cast iron heat sink, 1/6 of the steel heat sink, and 1/3 of the copper heat sink;

1. Simple installation and convenient maintenance. Due to the low density of aluminum alloy, and it can be processed into parts of various shapes and specifications, the cross section of this aluminum heatsink is large and regular, product assembly and surface treatment can be completed in one step, and it can be installed directly on the construction site, saving a lot of installation. cost. Maintenance is also convenient and the cost is low;

2. Energy saving and consumption reduction, low cost . When the center distance of the heat sink inlet and outlet and the heat conduction temperature are the same, the heat dissipation of the aluminum heat sink is 2.5 times higher than that of the cast iron radiator, and because of its beautiful appearance, no heating cover can be added, which can reduce the heat loss by more than 30% and reduce the cost by 10% or more, although the thermal performance of the aluminum heat sink is slightly inferior to that of the copper heat sink, the weight can be greatly reduced. Since the price of aluminum is only 1/3 of that of copper, the cost can be greatly reduced;

3. Aluminum extruded heat sink has corrosion resistance and long service life. A thick and solid oxide film can be formed on the surface of the aluminum alloy material, which can be used for a long time in the heating water quality of pH≤9 or in the car water tank, and the aluminum heat sink with special surface treatment can be used in various pH≤12. Long-term use of the material;

4. The aluminum profile heat sink extrusion can be treated with various surface finish, with a variety of colors, strong decoration, beautiful and durable, and can meet people's personalized requirements;

5. Safe to use and withstand the high pressure. Because the specific strength and specific stiffness of aluminum alloys are much higher than copper, cast iron and steel. Even in the case of thin thickness, it can withstand enough pressure, bending force, pulling force and impact force, and there will be no damage during handling, installation and using.
