1. Corrosion resistance
Compared with other metal materials, aluminum profiles
have low density and good corrosion resistance. Aluminum is widely used because it shows excellent corrosion resistance in air, water (or salt water), petrochemical and many chemical systems.
2. Electrical conductivity
Aluminum is used in the electrical manufacturing industry because of its excellent electrical conductivity, which is nearly twice as high as that of copper on a weight equal basis, so it is very popular in the electrical manufacturing industry.
3. Thermal conductivity
The thermal conductivity of aluminum is about 50 to 60 percent that of copper, which is useful in the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automobile cylinder heads and radiators.
Aluminum profiles are non-ferromagnetic, which is very important for the electrical manufacturing industry.
5. Flame retardant
Aluminum profiles cannot spontaneously ignite, which is necessary for applications involving handling or contact with flammable and explosive materials.
Formability means that specific tensile strength, yield strength, ductility and corresponding work-hardening rate govern the variation of allowable deformation. Compared with other metal materials, aluminum profiles are better formable and easier to be made into shapes needed by all walks of life.
Aluminum profiles have high recyclability. The properties of recycled aluminum are almost indistinguishable from virgin aluminium.
