The density of aluminum profile is only 2.7g/cm3, which is about 1/3 of steel, copper or brass density (7.83g/ cm3, 8.93g/ cm3) respectively. Under most environmental conditions, aluminum can display excellent corrosion resistance, including air, water (or brine), petrochemistry and many chemical systems.
Aluminum profile is often chosen because of its excellent electrical conductivity. On the basis of equal weight, the conductivity of aluminum is nearly two times that of copper.
Thermal conductivity rate
The thermal conductivity of the aluminum alloy is about 50-60% of the copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and the cylinder head and radiator of the car.
Aluminum profiles are non-ferromagnetic, which is an important feature for the electrical industry and the electronics industry. Aluminum profiles are not self ignition, which is important for the application of loading and unloading or contact with flammable and explosive materials.
