1. Corrosion resistance
The density of Aluminum extrusions profile is only 2.7g / cm3, which is about 1/3 of the density of steel, copper or brass (respectively 7.83g / cm3, 8.93g / cm3) Under most environmental conditions, including air, water (or brine), petrochemistry, and many chemical systems, aluminum can exhibit excellent corrosion resistance.
2. Conductivity
Aluminum profiles are often selected because of their excellent electrical conductivity. On the basis of equal weight, the conductivity of aluminum is close to 1/2 of copper.
3. 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.
