The aluminum profile is a mineral non-ferrous metal aluminum alloy. The aluminum profile has good corrosion resistance. The density of the aluminum profile is only 2.7/cm, which is about 1/3 of the density of steel, steel or brass. Under most environmental conditions, including air, water (or salt water), petrochemical and many chemical systems, aluminum can show excellent corrosion resistance.

　　The length of the aluminum profile is ferromagnetic, which is an important characteristic for the electrical and electronic industries. Aluminum profiles are not spontaneously combustible, which is important for applications involving handling or contact with flammable and explosive materials.

　　The machinability of aluminum profile is excellent. In various deformed aluminum alloys and forged aluminum alloys, as well as in the various states that these alloys have after being produced, the machining characteristics vary considerably, which requires special machine tools or technology.

　　Specific tensile strength, yield strength, ductility and corresponding work hardening rate dominate the change in allowable deformation.

　　 aluminum profile is selected because of its excellent electrical conductivity. In an environment of equal weight, the conductivity of aluminum is nearly twice that of copper.

　　The thermal conductivity of aluminum alloy is about 50-60% of copper, which is beneficial for the manufacture of heat exchangers, evaporators, heating appliances, and automobile cylinder heads and radiators.
