5A06 5A06 aluminum components Mechanical Performance Overview Features Uses Physical properties Chemical treatment specifications 5A06 Overview Features Uses mechanical properties of the physical properties of the chemical composition heat treatment specifications Expand Standard: GB / T 6892-2000 Edit this section outlines the characteristics 5A06 5A06 aluminum as Al-Mg-based prevention rust aluminum, 5A06 aluminum with high strength and corrosion stability, in the annealed state and extruded plastic is still good, with TIG weld and weld airtight plastic is acceptable, gas welding and spot welding joint strength 90 to 95% of the matrix strength; good machinability. Uses ① high magnesium alloy, in non-heat treatable alloys good strength, corrosion resistance, good machinability. Surface appearance after anodization. Good arc performance. 5A06 alloy as the main alloying elements of magnesium, has good corrosion resistance and weldability, and moderate intensity. Excellent corrosion resistance makes 5A06 alloy is widely used in marine uses such as ships, as well as automobiles, aircraft welding parts, metro and light rail, should be strictly fireproof pressure vessel (such as liquid tankers, refrigerated trucks, refrigerated containers), refrigeration equipment, tower, drilling equipment, transportation equipment, missile parts, armor and so on. 5A06 aluminum ②5A06 belong 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 is the 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, with a variety of liquid containers and other small loads produced by deep drawing parts: wire used to make rivets edit this section Physical properties Chemical composition Al Al: margin silicon Si: ≤0.40 copper Cu: ≤0.10 magnesium Mg: 5.8 ~ 6.8 Zinc Zn: ≤0.20 Manganese Mn: 0.50 ~ 0.8 Titanium Ti: 0.02 ~ 0.10 Beryllium Be: 0.0001 ~ 0.005 iron Fe: 0.000 ~ 0.400 Note: Single: ≤0.05; Total: ≤0.10 Mechanical Properties Tensile strength σb (MPa): ≥315 Conditions yield strength σ0.2 (MPa): ≥160 Elongation δ10 (%): ≥15 Note: longitudinal bars at room temperature mechanical properties of the sample size: bar diameter (square bar, hexagonal bar inscribed circle diameter) ≤150 Heat treatment 1) homogenization: Heat 460 ~ 475 ℃; insulation 12 ~ 14h; air cooling. 2) rapid thermal annealing: heating 310 ~ 350 ℃; holding time 30 ~ 120min; air or water. 3) high temperature annealing: heating 310 ~ 335 ℃; finished thickness ≥6mm or <6mm, the holding time of 30 ~ 180min or 30 ~ 120min; air cooling. 4) low-temperature annealing: heating 250 ~ 300 ℃ or 150 ~ 180 ℃; holding time of 1 ~ 2h or air-cooled 2 ~ 3h status: aluminum and aluminum alloy extruded profiles (H112 condition)
