从United States供应商批发进口Alloy 5052 Aluminum Coils — FOB条款

5052 aluminum coils is Aluminum-magnesium alloy aluminum coils. Mg is the main alloying element in 5052 aluminum coils. It is the most widely used rust-proof aluminum. The alloy is high in nature, especially fatigue resistance, plasticity and corrosion resistance, with high strength. It can not be heat-treated, the plasticity of it is good in semi-cold hardening. Itâ??s low in plasticity during cold hardening, and good in corrosion resistance with good weldability, poor machinability and polishing. The main alloying element of 5052 aluminum sheet is magnesium, and aluminum-magnesium alloy also contains a small amount of Mn, Cr, Ni, Ti, etc. Most of the Mn in the alloy forms MnAl6 except for a small amount of solid solution. In the interior of the 5052 aluminum coils, the effect of Cr is similar to that of Mn, which improves the resistance to stress corrosion cracking, improves the strength of the base metal and weld, and reduces the tendency of weld cracking, but its content generally does not exceed 0.35%. Surface Advantages of 5052 Aluminum coils: 1 - surface of 5052 aluminum coils is not allowed to have cracks, corrosion spots and traces of nitrate. 2 - The surface is allowed to have peeling, air bubbles, surface roughness. and it is also allowed to have local mechanical damage with a depth not exceeding 8% of the nominal thickness of the part where the defect is located. But the maximum depth of the defect shall not exceed 0.5 mm, and the total area of the defect shall not exceed the total area of the coils 5%. 3 - Allow the supplier to illuminate the profile longitudinally to a smooth surface. 4 - Other requirements: There are demanders and suppliers to draw up their own. Application of 5052 Aluminum coils: 5052 aluminum coils is mainly used for high plasticity with good weldability. It is also commonly used in transportation vehicles, ship sheet metal parts, instruments, street lamp brackets and rivets, hardware products, electrical enclosures, etc. It can also be used to manufacture aircraft fuel tanks, oil pipes, aerospace aluminum alloy materials, and is a typical rustproof alloy material. The atates of 5052 aluminum coils includes F, O, H12, H14,, H16, H18, H19, H22, H24, H26, H28, H32, H34, H36, H38, H111, H112, H114.
