5083-H321 aluminum

5083-H321 aluminum Alcoa 5083H-321: machined aluminum alloy plate 5083-H321 Overview 5XXX series of aluminum, magnesium alloy, is a kind of moderate strength, corrosion resistance and good weldability of aluminum on behalf of products, from sheets the planks are widely used in all areas. Characteristics of 5083-H321 is a high-magnesium alloy, in non-heat treatable alloy, good strength, corrosion resistance, good machinability. Surface appearance after anodization. Good arc performance. 5083-H321 alloy as the main alloying elements of magnesium, has good corrosion resistance and weldability, and moderate intensity. Excellent corrosion resistance makes 5083-H321 alloys are widely used in marine uses such as ships, as well as automobiles, aircraft welding parts, metro and light rail, it should be strictly fireproof pressure vessel (such as liquid tankers, refrigerated trucks, refrigerated containers), refrigeration equipment, TV tower, drilling equipment, transportation equipment, missile parts, armor, etc. Scope 5083-H321 belonging to Al-Mg-Si alloy, using a wide range, especially in the construction industry can not do without this alloy is the most promising alloys. Good corrosion resistance, weldability, cold is better, and with moderate intensity. 5083-H321 main alloying elements of magnesium, has good forming properties, corrosion resistance, weldability, moderate intensity, for the manufacture of aircraft fuel tanks, pipelines, and transportation vehicles, ship sheet metal parts, instruments, lights bracket and rivets, metal products, electrical appliances, such as Shell. ③ AL-Mn alloy, is the most widely used as a rust-proof aluminum, high strength of this alloy, especially those with fatigue strength: high ductility and corrosion resistance, heat treatment can enhance the half-cold hardening ,, plasticity is good, when the plastic work hardening is low, good corrosion resistance, good weldability, machinability bad, can be polished. Mainly used for high plasticity and good weldability, working in a liquid or gaseous medium low load parts, such as mailboxes, gas or oil pipe. 5083-H321 chemical composition of grade silicon; 0.4 Fe; 0.4 Cu; 0.10 Mn; 03.-1.0 chromium; zinc 4.4-4.9; 0.05-0.25 titanium; 0.25 0.15 Other 0.05 0.15 ;; aluminum; the balance of mechanical performance analysis; (250 ℃ MPa) Tensile strength aluminum alloy grades and status; (250 ℃ MPa) 275-320 yield strength; 500kg force 10mm ball 210 hardness; 1.6mm (1 / 16in) 65 elongation; 1.6mm (1 / 16in) 16 physical Performance Analysis aluminum alloy grades and status of thermal expansion coefficient (20-100 ℃) um / mk melting range (℃) conductivity 20 ℃ (68 ° F) (% ACS) Resistivity 20 ℃ (68 ° F) m m / m 5083H321 23.4 570-64029 0.059 [
