Aluminum is an aluminum-magnesium alloy that has undergone special treatments such as high-temperature oxidation. It is usually called "aluminum oxide". It is a white powder and is a covalent compound. It has a melting point of 2050°C, a boiling point of 3000°C, and a true density of 3.6g/cm3. It has good fluidity and is insoluble in water and can be dissolved in molten cryolite. It can also withstand thousands of degrees of high temperature and strong impact. It is an aluminum product with high strength and anti-corrosion performance. It is lightweight and durable. Therefore, the high-power wall washer lamp using aluminum is not only lightweight, but also hard. The strength is high, the load-bearing capacity is also great, and the heat dissipation performance is also very good.

    There are three important steps in the processing of high-power wall washer aluminum shell. Choice of aluminum plates. Aluminum is very important. The raw materials are all high-quality aluminum or aluminum alloy.　

　First, the raw materials for processing aluminum shells are all high-quality aluminum or aluminum alloys. Southwest Chongqing Aluminum is very good, followed by Guangdong Aluminum and Shanghai Aluminum. These raw materials can ensure the surface treatment process of the aluminum shell, which directly affects the service life and strength of the aluminum shell. Second, processing equipment and technology. Processing equipment and technology are indispensable. Only when these two are guaranteed, can the aluminum shell processing standard be reached. Advanced equipment can guarantee the specifications and standards of aluminum casing, and high technology can guarantee defective products of aluminum casing. Increase productivity. Third, processing equipment and processing technology. The processing equipment should adopt advanced imported equipment, which can ensure that the surface temperature of the product is uniform and the color depth is consistent. Achieve strong adhesion of the surface layer. Will not fall off easily.

    High-power wall washer lights are generally made of aluminum, such as die-cast aluminum, car aluminum, and stretched aluminum. Compared with stainless steel, it has the following advantages:

　　1, high-power wall washer requires materials with good heat dissipation, and aluminum has a much larger thermal conductivity than steel;

　　2, aluminum profile is easy to process, many shops can do it, and it is convenient to obtain materials;

　　3, there is a layer of dense alumina on the surface of aluminum, which has a good anti-oxidation and corrosion effect;

　　4, lastly, aluminum is cheaper than stainless steel, and the price is reasonable.

    Aluminum is an environmentally friendly, non-fading, and cost-effective metal. It has better environmental protection than ordinary copper and better non-oxidation than stainless steel. It is durable and affordable while maintaining its beautiful appearance. It has become a favorite of consumers.

    The use of aluminum shell for high-power wall washer can increase the life of the lamp and make the LED lamp shell look elegant. However, aluminum lamp housings are expensive and expensive to construct, and the lamp housings need to be processed by machine tools. Therefore, some high-quality, medium-quality high-power wall washers will use aluminum lamp housings.
