Characteristics of aluminum profiles
1, 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.
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.
3, thermal conductivity rate
Aluminum alloys have a thermal conductivity of about 50-60% of copper, which is advantageous for the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automotive cylinder heads and radiators.
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.
The machinability of the aluminum profile 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.
The specific tensile strength, yield strength, ductility, and corresponding work hardening rate govern the variation in allowable deformation.
Aluminum is extremely recyclable, and the properties of recycled aluminum are almost indistinguishable from that of primary aluminum.
