Aluminum Profiles Characteristics

Corrosion resistance

The density of aluminum is only 2.7g / cm3, about the steel, copper or brass density (7.83g / cm3,8.93g / cm3, respectively), 1/3. Aluminum shows excellent corrosion resistance under most environmental conditions, including air, water (or brine), petrochemistry, and many chemical systems.


Aluminum is often chosen for its excellent electrical conductivity. On the basis of equal weight, the electrical conductivity of aluminum is nearly double that of copper.

Thermal conductivity rate

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


Aluminum profiles are non-ferromagnetic and are an important feature for the electrical and electronics industries. Aluminum profiles are not self-ignitable and are important for applications involving handling or exposure to flammable materials.


Machinability of aluminum profiles is excellent. In a variety of deformed aluminum and cast aluminum alloys, as well as in the various states possessed by the alloys after they have been produced, the machining characteristics vary considerably, requiring special machine tools or techniques.


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


Aluminum has a very high recyclability, the characteristics of recycled aluminum and primary aluminum almost no difference.
