The advantages of aluminium alloy high thermal conductivity material being widely used

Existing research on the thermal conductivity of aluminium alloys is mainly focused on deformed aluminium alloys. Deformed aluminium alloys for thermal conductivity are mainly used in automotive and electronic fields, such as aluminium radiators, heaters and air conditioners. Compared with traditional copper or steel radiators, aluminium radiators have the advantages of light weight, good corrosion resistance and low cost of use, and have now been widely used. For example, the current ratio of aluminium in radiators for foreign cars is 95% in Europe, 90% in the US and 75% in Japan; in computer radiators, aluminium radiators have become the mainstream, replacing copper/steel radiators and plastic fans. The disadvantage of deformed aluminium alloys is that they are difficult to make into parts with complex structures.

Aluminium is one of the most widely used metals in the manufacture of radiators. Aluminium alloys have low density, high thermal conductivity, good ductility and high strength, making them a key material for the production of lightweight, high performance heat sink components. Processing techniques for aluminium radiators include extrusion, stamping, milling, tooth shovelling, die casting, stir friction welding and brazing.

In recent years, a number of new aluminium processing technologies have emerged, demonstrating advantages in terms of dimensional accuracy, product quality, high performance and light weight. Aluminium radiators are being used more and more widely and are becoming more and more popular with users, mainly because of the unique advantages that aluminium radiators have.

1, corrosion resistance, long service life. Aluminum alloy materials can generate a thick layer of solid oxide film on the exterior, which can be used for a long time in the heating water quality of pH ≤ 9 or in the water tank of the car, while the aluminum radiator can be used for a long time in various raw materials of pH ≤ 12 through special exterior treatment.

2, can be a variety of appearance disposal, colour variety, and no welding joints, strong decorative, beautiful and durable, can satisfy everyone's personalized needs.

3, safe to use, high pressure. Because the specific strength and stiffness of aluminium alloy is much higher than that of copper, cast iron and steel. Even in the case of thin thickness, it can accept large enough pressure, bending force, tensile force and impact force, and will not present damage in the process of transfer, installation and use.
