At present, there are two main types of aluminum radiators on the market: high-pressure and stretched aluminum alloy welding. The aluminum radiators sold in the Chinese market are mainly of welded type, as the strength of their welding points cannot be guaranteed, which can easily cause problems and water leakage. Therefore, consumers should choose carefully. In addition, consumers should be reminded that since aluminum radiators are not suitable for alkaline water quality and are different from steel, they should be avoided from being mixed with other materials for installation.

Characteristics of aluminum alloy: The heat dissipation of aluminum alloy is very good, while the corrosion resistance of aluminum alloy is very poor.

The chemical activity of aluminum in the alloy is very active, and it is easy to react quickly with oxygen in the air, forming a dense aluminum oxide protective film with a thickness of about 1 μ m. It has a very strong bond with the substrate, passivating the surface of the coating and preventing the continuation of self oxidation. So aluminum alloy itself is not afraid of oxygen and does not have oxygen corrosion.

The principle of internal anti-corrosion of radiators: The internal anti-corrosion treatment of radiators is to apply a layer of organic paint with good adhesion (adhesion) and corrosion resistance on the inner surface of the radiator, isolating water from steel or aluminum, thereby playing a anti-corrosion role.

Due to the dense aluminum oxide protective film on the surface of aluminum alloy, it is difficult for the anti-corrosion coating to adhere. Even if applied, the anti-corrosion coating blocks on the inner surface of aluminum alloy are easily detached under the scouring of water inside the radiator. So aluminum radiators cannot be used in centralized heating systems, but they are very suitable for use in self heating systems.

Compared to steel radiators, aluminum radiators have a very prominent advantage in self heating systems. Therefore, some manufacturers in China have launched energy-saving combinations of wall mounted furnaces and aluminum alloy radiators, specifically designed for households with self heating. This should be a very good choice.

Summary: The above is an introduction to the characteristics and benefits of aluminum alloy radiators, hoping to be helpful to everyone. If you would like to learn more related information, please continue to follow our website.
