Analysis of the difference between iron shell and aluminum shell of led rainproof power supply

The main differences between the iron shell and aluminum shell of the LED rainproof power supply with the same power and circuit are as follows:

　　 1. At the same power, the aluminum shell is light in weight and easy to install. The iron shell is heavy and requires higher installation requirements. Because the specific gravity of aluminum is lighter than that of iron, aluminum=2.85g/cm3; iron=7.85g/cm3.

　　 2. Aluminum shell products do not rust, and iron shells are easy to rust. The main cause of metal rust is electrochemical corrosion and air oxidation. Aluminum will also rust after being oxidized, forming a dense oxide film, that is, aluminum oxide, which prevents further oxidation of metal aluminum. Aluminum will also rust after being oxidized, forming a dense oxide film, that is, aluminum oxide, which prevents further oxidation of metal aluminum. The sparse oxide film produced after iron rusts accelerates the oxidation of the metal to form iron trioxide, that is, rust.

　　3. Aluminum has better heat dissipation performance than iron, and has a lower temperature rise, which can greatly extend the service life of the product.

　　4. The strength and hardness of the iron shell is higher than that of the ordinary aluminum shell. The impact resistance is better.

　　 5. The price of the iron case is lower than that of the aluminum case. 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. This type of iron shell is cost-effective.
