What are the characteristics of aluminum profiles?

Aluminum profiles are aluminum materials with different cross-sectional shapes through hot melting and extrusion of aluminum rods. The production process of aluminum profiles mainly includes three processes: casting, extrusion and coloring. What are the characteristics of aluminum profiles produced by aluminum profile manufacturers? 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. Conductivity: Aluminum profile is often selected because of its excellent 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 that of copper, which is more advantageous for the manufacture of heat exchangers and evaporators. 4. Non-ferromagnetic: Aluminum profiles are 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 aluminum profiles is excellent. 6. Formability: The specific tensile strength, yield strength, ductility and corresponding work hardening rate dominate the change in allowable deformation. 7. Recyclability: Aluminum has extremely high recyclability, and the characteristics of recycled aluminum are almost indistinguishable from primary aluminum.
