Why are aluminum radiator materials so popular?


2020-06-12


Nowadays, there are more and more manufacturers of aluminum radiator materials on the market, and the use scope of aluminum radiator materials is more and more extensive. Why are aluminum profile radiators so popular? Here is Hefei Analu International Trading Co., Ltd. to introduce the advantages of this material.

Advantages of Aluminum Alloy Radiator

1. The heat dissipation of aluminum alloy is very good, and the corrosion resistance of the aluminum alloy is very poor.

2. The chemical activity of aluminum in the alloy is very lively and easily reacts quickly with oxygen in the air to form a dense aluminum oxide protective film. The thickness of the film is about 1μm. Its combination with the substrate is very strong, making The surface of the coating is passivated to prevent its own oxidation from continuing. Therefore, the aluminum alloy itself is not afraid of oxygen, and there is no oxygen corrosion.

The principle of internal anti-corrosion of the radiator: the internal anti-corrosion treatment of the radiator is to coat a layer of organic paint with good adhesion (adhesion) and anti-corrosion ability on the inner surface of the radiator to isolate the water from the steel or aluminum material. To antiseptic effect. The aluminum alloy aging furnace has a dense aluminum oxide protective film on the surface, so it is difficult to adhere to the anti-corrosion coating. Even if it is applied, the anti-corrosion coating block on the surface layer of the aluminum alloy is easily peeled off under the scouring of the water inside the radiator. Therefore, aluminum alloy radiators must not be used in central heating systems, but they are very suitable for self-healing systems.

3. Compared with steel radiators, aluminum alloy radiators have very prominent advantages in self-heating water removal systems. So now there are domestic manufacturers that have launched energy-saving combinations of wall-hung boilers and aluminum alloy radiators, which are specially provided to For a heated family, this should be a very good choice.

Through the above three aspects, I have wondered why the application of aluminum alloy radiators is so common now, entirely because of its own superiority.
