Characteristic

Corrosion resistance:

The density of 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). Under most environmental conditions, including air, water (or salt water), petrochemicals and many chemical systems, aluminum can show excellent corrosion resistance.

Conductivity

Aluminum profile is often selected because of its excellent electrical conductivity. On the basis of equal weight, the conductivity of aluminum is close to 1/2 of that of copper.

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 heads and radiators.

Non-ferromagnetic

Aluminum profiles are non-ferromagnetic, which is an important feature 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.
