Aluminum profile

Corrosion resistance
The aluminum profile has a density of only 2.7 g/cm3, which is about 1/3 of the density of steel, copper or brass (7.83 g/cm3, 8.93 g/cm3, respectively). Aluminum exhibits excellent corrosion resistance under most environmental conditions, including air, water (or brine), petrochemicals, and many chemical systems.
Conductivity
Aluminum profiles are often chosen for their excellent electrical conductivity. On the basis of equal weight, the electrical conductivity of aluminum is nearly twice that of copper.
Thermal conductivity rate
The thermal conductivity of aluminum alloys is about 50-60% of that of copper, which is advantageous for the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and cylinder heads and radiators for automobiles.
Non-ferromagnetic
Aluminum profiles are non-ferromagnetic, which is an important feature for the electrical and electronics industries. Aluminum profiles are not self-ignitable, which is important for applications involving handling or contact with flammable and explosive materials.
Machinability
The machinability of aluminum profiles is excellent. In various deformed aluminum alloys and cast aluminum alloys, and in various states after the production of these alloys, the machining characteristics vary considerably, which requires special machine tools or techniques.
Formability
The specific tensile strength, yield strength, ductility, and corresponding work hardening rate govern the variation in allowable deformation.
Recyclability
Aluminum has high recovery, and the characteristics of recycled aluminum are almost indistinguishable from that of primary aluminum.
