Practical characteristics of industrial aluminum

by:Zeyi     2021-05-21
1) Corrosion resistance; the density of industrial aluminum 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). Under most environmental conditions, including air, water (or salt water), petrochemicals and many chemical systems, aluminum can show excellent corrosion resistance.  2) Electrical conductivity: is often selected because of its excellent electrical conductivity. On the basis of equal weight, the conductivity of aluminum is nearly twice that 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. .   4) Non-ferromagnetic; industrial aluminum is non-ferromagnetic, which is an important feature for the electrical and electronic industries. Aluminum profiles are not spontaneously combustible, which is important for applications involving handling or contact with flammable and explosive materials.   5) Machinability: The machinability of industrial aluminum is excellent. In various deformed aluminum alloys and cast aluminum alloys, as well as in the various states that these alloys have after being produced, the machining characteristics change considerably, which requires special machine tools or technology.   6) Formability; the specific tensile strength, yield strength, ductility and corresponding work hardening rate dominate the change in allowable deformation.   7) Recyclability; aluminum has high recyclability, and the characteristics of aluminum that can be produced are almost indistinguishable from primary aluminum.
