Characteristics of aluminum profile

With the development of aluminum profile technology, everyone has higher and higher quality requirements for aluminum profiles. Aluminum profile manufacturers naturally have higher technical requirements for aluminum profile deep processing equipment and staff, and the flatness of the profile plane is one of the required quality indicators. So, what are the characteristics of aluminum profiles? '1. Corrosion resistance' The density of aluminum profile 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    aluminum profile 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 for the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automobile cylinder heads and radiators.  4, non-ferromagnetic   Aluminum profile 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 the aluminum profile 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 vary considerably, which requires special machine tools or technology. '6. Formability' The specific tensile strength, yield strength, ductility, and corresponding work hardening rate govern the change in allowable deformation.  7. Aluminum profiles are recyclable.   Aluminum has extremely high recyclability, and the characteristics of recycled aluminum are almost the same as those of primary aluminum.
