These machine tools have considerable changes in the state of machining as well as a variety of special features required for machining. Specific tensile strength, yield strength of single air shower, ductility and corresponding work hardening rate control the variation of allowable deformation. Aluminum is highly recyclable, and the properties of recycled aluminum are almost the same as that of primary aluminum. There are about 300 kinds of alloy and 1500 varieties of aluminum processing materials in China, which is a country with rich products in the world. A large number of advanced products and applications are emerging in China. However, the technology and equipment of the majority of small and medium-sized enterprises are still at the level of 1970s-1990s.
Export industrial aluminum profiles. 30000 tons, an increase of 49% over 2006. 5%, the net export of aluminum alloy profiles is 116. In 2007, the apparent consumption of industrial aluminum in China was 1. 50000 tons. After nearly 10 years of rapid growth, China's aluminum profile industry has entered a new stage of development, and has shown many new development trends. How much is the Banfeng shower room
The thermal conductivity of aluminum alloy is about 50-60% of that of copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, cylinder heads and radiators of automobiles. Aluminum profiles are non ferromagnetic, which is an important feature for the electrical and electronic industries. Aluminum profiles are not self ignited, which is important for applications involving handling or contacting flammable and explosive materials. The machinability of aluminum profiles is excellent. In a variety of wrought and cast aluminum alloys.
This process has the advantages of simple, practical and good effect. The film hardness of titanium gold aluminum profile prepared by this process is HV ≈ 1500. Under the same conditions, it is 150 times more wear-resistant than that of 22K gold plating. It can be processed into a variety of series of bright aluminum profile products, such as gold, color, black and so on. The density of aluminum profile is only 2. 7 g / cm3, which is about the density of steel, copper or brass (7. 83g/ cm3，8。 93 g / cm3). Aluminum exhibits excellent corrosion resistance, including in air, water (or brine), petrochemicals, and many chemical systems. From January to June of 2008, the output of alumina was 1112. 90000 tons, an increase of 7. After nearly 10 years of rapid growth, China's aluminum profile industry has entered a new stage of development, and has shown many new development trends. Aluminum profile is often selected because of its excellent conductivity. On the basis of equal weight, the conductivity of aluminum is nearly twice that of copper.
