The street lamp housing is a very common accessory, so Energy Saving Street Light Housing Wholesale will share the cooling function and role of the street lamp housing.
The plastic material of the aluminum profile shell is generally lighter and the hardness is higher. Many engineering plastics are even stronger than metals. The density of aluminum profiles is very small, only 2.7g / cm. Although it is relatively soft, it can be made into various aluminum profile alloys, such as hard aluminum profiles, super hard aluminum profiles, anti-rust aluminum profiles, cast aluminum profiles, etc. These aluminum alloys are widely used in manufacturing industries such as airplanes, cars, trains, and ships. In addition, space rockets, space shuttles, and satellites also use many aluminum profiles and their aluminum alloys. For example, a supersonic aircraft is composed of about 70% aluminum profiles and its aluminum profile alloys. Aluminium profiles are also widely used in ship building, and the volume of aluminum profiles for a large passenger ship often reaches several thousand tons.
The conductivity of aluminum profiles is second only to industrial aluminum profiles accessories silver and copper, although its conductivity is only 2/3 of copper, but the density is only 1/3 of copper, so the same amount of electricity is transported, and the quality of aluminum profile wire is only Half of the copper wire. The oxide film on the surface of the aluminum profile is not only resistant to corrosion, but also has certain insulation. Therefore, the aluminum profile has a wide range of uses in the electrical appliance manufacturing industry, wire and cable industry and radio industry.
