Corrosion resistance
The density of the aluminum profile is only 2.7g/cm3, which is about 1/3 of the density of steel, copper or brass (7.83g/cm3, 8.93g/cm3, respectively). In most environmental conditions, including air, water (or brial), petrochemicals, and many chemical systems, aluminum can show excellent corrosion resistance.
Conductivity
Aluminum profiles are often chosen because of their excellent conductivity. On the basis of equal weight, aluminum has a conductivity of nearly 1/2 of that of copper.
Thermal conductivity
The thermal conductivity of aluminum alloys is about 50-60% of copper, which is beneficial for the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, as well as automotive cylinder head and radiators.
Non-ferromagnetic
Aluminum profiles are non-ferromagnetic, which is an important feature for the electrical and electronics industries. Aluminum profiles are not self-igniting, which is important for applications involving loading and unloading or contact with flammable and explosive materials.
Processability
The processability of aluminum profiles is excellent. In various deformed aluminum alloys and cast aluminum alloys, as well as in the various states after the output of these alloys, the machine processing characteristics change quite a lot, which requires special machine tools or techniques.
Formability
Specific stretch strength, yield strength, scalability, and corresponding process hardening rates dictate the changes in the amount of deformation allowed.
Recycling
Aluminum is highly recyclable, and the properties of recycled aluminum are almost indesoluent from that of primary aluminum.
