Wholesale 5083 5083 marine aluminum rust-proof aluminum alloy corrosion-resistant aluminum alloy 5083 Shanghai Xiang Island US wholesale agent ALcoa quality aluminum, aluminum rod, aluminum tubes, Sumitomo / Kobe high-precision aluminum and aluminum alloy Korea Po items, molds for Russia / automobile manufacturing special aluminum alloy with high quality anodized aluminum rust-proof aluminum plate with high precision high-strength aerospace aluminum superhard industrial aluminum. Authoritative quality assurance, special custom specifications acceptable production (with the original material goods allotment Paul * / Material Laboratory: SGS / ROHS Report) 5083 AL-Mg system is typical rust-proof aluminum alloy, which is characterized by excellent welding performance and good corrosion resistance. Processing performance, combined with low temperature performance and reasonable. 5083 5083 alloy welding welding performance is good, can be a variety of welding methods of welding, weld strength can be equal to the matrix strength annealed. Also has good extension has been resistance, cold formability, corrosion resistance and reliable, as the temperature decreases, the tensile strength of metal and welded joints of the matrix, yield strength, elongation rate will be increased, very good low-temperature toughness. 5083 5083 alloy corrosion various states have good corrosion resistance, the atmosphere, fresh water, sea water, alcohol, gasoline and diesel, organic acids, concentrated nitric acid, a variety of food have good corrosion resistance. But 5083 alloy susceptible to stress corrosion cracking (scc), in order to avoid the occurrence of stress corrosion cracking, 5083 alloy operating temperature not exceeding 65 C is appropriate. 5083 aluminum alloy chemical composition of Al Al: margin silicon Si: ≤0.40 copper Cu: ≤0.10 magnesium Mg: 4.0 ~ 4.9 Zinc Zn: ≤0.25 Manganese Mn: 0.40 ~ 1.0 Titanium Ti: ≤0.15 chromium Cr: 0.05 ~ 0.25 iron Fe : 0.000 to 0.400 Note: Individual: ≤0.05; Total: ≤0.15 5083 tensile mechanical properties of aluminum σb (MPa): ≥270 Conditions yield strength σ0.2 (MPa): ≥110 Elongation δ10 (%): ≥20 Elongation δ5 (%): ≥12 Note: vertical pipe at room temperature mechanical properties of the sample size: All Thickness
