Features of Aluminum Alloy Profiles
Mar 30, 2018
1) corrosion resistance;
The density of the aluminum profile is only 2.7g/cm3, which is about the density of steel, copper or brass (7.83g/ cm3, 8.93g/ cm3, respectively), and 1/3. In most environmental conditions, including in air, water (or brine), petroleum chemistry, and many chemical systems, aluminum shows excellent corrosion resistance.
2) electrical conductivity;
Aluminum profiles are often chosen because of their excellent electrical conductivity. On the basis of equal weight, the electrical conductivity of aluminum is nearly two times more than that of copper.
3) the rate of thermal conductivity;
The thermal conductivity of aluminum alloy is about 50-60% of copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automobile cylinder head and radiator.
4) non ferromagnetism;
The aluminum profile is non ferromagnetic, which is an important characteristic for the electrical industry and the electronics industry. Aluminum is not self burning, which is important for the application of loading and unloading or contact with flammable and explosive materials.
The machinability of aluminum profiles is excellent. In all kinds of deformation aluminum alloy and cast aluminum alloy, and after all these alloys have various states, machining characteristics change quite large, which requires special machine tools or technology.
The specific tensile strength, yield strength, ductility, and the corresponding hardening rate dominate the change of the allowable deformation.
Aluminum is highly recyclable, and the properties of recycled aluminum are almost no different from that of primary aluminum
