Aluminum shell 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 still 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 of the vessels used to build 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 industry, wire and cable industry and the radio industry has a wide range of uses.
Third, aluminum is a good conductor of heat, and its thermal conductivity can be three times larger than iron, industrial aluminum can be used to produce a variety of heat exchangers, cooling materials and cooking utensils.
Fourth, aluminum has a good ductility (its ductility after gold and silver), in the 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.
