At the same power, the aluminum shell is light in weight and easy to install. The iron shell is heavy and the installation requirements are higher.
Since aluminum has a specific gravity lower than that of iron, aluminum = 2.85 g/cm3; iron = 7.85 g/cm3.
The aluminum casing product does not rust, and the iron shell is easy to rust.
The cause of metal rust is mainly the effect of electrochemical corrosion and air oxidation. Aluminum is also rusted after being oxidized to form a dense oxide film, that is, aluminum oxide, thereby preventing further oxidation of the metal aluminum. Aluminum is also rusted after being oxidized to form a dense oxide film, that is, aluminum oxide, thereby preventing further oxidation of the metal aluminum. The oxide film produced after the iron is rusted is loose, which accelerates the oxidation of the metal to form ferric oxide, that is, rust.
The heat dissipation performance of aluminum is better than that of iron and the temperature rise is low, which can greatly extend the service life of the product.
Thermal conductivity (heat transfer coefficient): aluminum = 237 W / mK, iron = 80 W / mK. It can be seen that the heat transfer coefficient of aluminum is three times that of iron, so the heat dissipation performance of aluminum shell is better than that of iron shell.
The strength and hardness of the iron shell are higher than those of ordinary aluminum shells. The impact resistance is better.
The price of the iron shell is lower than that of the aluminum shell. The surface is coated with a layer of metal that is not easily corroded, such as zinc, tin, chromium, nickel, etc., which not only increases the corrosion resistance but also reduces the material cost, and the iron shell is cost-effective.
