Aluminium Enclosure Housing and Shells plastic material is generally relatively light, hardness is also high, many of the strength of engineering plastics even more than metal. For cost and light considerations, the lighter weight, small fever notebook can buy a better design of plastic cooling base. But if it is a larger weight, fever, the higher the notebook is recommended to buy metal materials, good work of the cooling base.
First, the density of aluminum is very small, only 2.7g / cm, although it is relatively soft, but can be made of various aluminum, such as hard aluminum, super hard aluminum, rust aluminum, cast aluminum and so on. These aluminum alloys are widely used in aircraft, cars, trains, boats and other industries. In addition, the universe rocket, space shuttle, satellites also use a lot of aluminum and its aluminum alloy. For example, a supersonic aircraft consists of about 70% of aluminum and its aluminum alloy. Many ships use aluminum, a large passenger ship with aluminum often up to several thousand tons.
Second, the conductivity of aluminum after silver, copper, although its conductivity as long as the copper 2/3, but the density of copper as long as 1/3, so the same amount of electricity, the quality of aluminum as long as half of the copper The Aluminum oxide film is not only corrosion-resistant, and there is a certain insulation, so aluminum in the electrical manufacturing industry, wire and cable industry and the radio industry has a wide range of uses.
Third, aluminum is a good conductor of heat, its thermal conductivity can be three times larger than the iron, the industry can be made of aluminum heat exchanger, heat dissipation and cooking utensils.
Fourth, aluminum has a good ductility (its ductility after gold and silver), at 100 ℃ ~ 150 ℃ can be made thinner than 0.01mm aluminum foil. These aluminum foil is widely used in packaging cigarettes, candy, etc., can also be made of aluminum wire, aluminum, and can roll all kinds of aluminum products.
What are the main processes of Aluminium Enclosure Housing and Shells coloring?
(1) surface pretreatment: chemical or physical method to clean the surface of the profile, exposed pure matrix, in order to facilitate access to complete, dense artificial oxide film. It is also possible to obtain a mirror or matte (matt) surface by mechanical means.
(2) anodizing: the surface pretreatment of the profile, under certain conditions, the substrate surface anodic oxidation, resulting in a layer of dense, porous, strong adsorption capacity of the AL203 film.
(3) Sealing: The pores of the porous oxide film formed by anodic oxidation are closed, so that the oxide film is resistant to contamination, and the corrosion resistance and abrasion resistance are enhanced. The oxide film is colorless and transparent, the use of sealing before the strong adsorption of the film, in the membrane hole adsorption deposition of some metal salts, the appearance of the appearance of the appearance (silver) outside the many colors, such as: black, bronze, Gold and stainless steel color.
