1.Corrosion resistance
The density of aluminum profiles 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). Aluminum exhibits excellent corrosion resistance under most environmental conditions, including in air, water (or brine), petrochemicals, and many chemical systems.
2.Conductivity
Aluminum profiles are often chosen due to their excellent electrical conductivity. On an equal weight basis, the conductivity of aluminum is approximately 1/2 that of copper.
3.Thermal conductivity
The thermal conductivity of aluminum alloys is about 50-60% of that of copper, which is beneficial for the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automobile cylinder heads and radiators.
4.Non-ferromagnetic
Aluminium profiles are non-ferromagnetic, an important property for the electrical and electronic industries. Aluminium profiles are not self-igniting, which is important for applications involving handling or contact with flammable and explosive materials.
5.Processability
The workability of aluminum profiles is excellent. Among various wrought and cast aluminum alloys, and in the various states in which these alloys are produced, the machining properties vary considerably, requiring special machine tools or techniques.
6.Formability
The specific tensile strength, yield strength, ductility and corresponding work hardening rate govern the variation in allowable deformation.
7.Recyclability
Aluminum is extremely recyclable, and the properties of recycled aluminum are almost indistinguishable from virgin aluminum.
