Micro Pins Micro Pins,Micro Spring Pins,Electric Micro Pins,Stainless Steel Micro Pins Shenzhen Long Wei Wang Precision Technology Co., Ltd. , https://www.electronichdwe.com Incomplete annealing; 150~300oC. 2~3h, air-cooled; fully annealed: 390~420oC, air-cooled or water-cooled after heat-transmission (0.5h) In the annealed state, a solid solution and a ß phase (Al 3 Mg 2 ) are formed. Alloy of Fe, Si may form Mg 2 Si and Al 3 Fe, the alloy may have: AlMg2Mn, AlFeSi like compound  Low magnesium containing Al-Mg alloy, non-heat strengthened, low strength, high ductility, cold deformation can strengthen the alloy, but the ductility is reduced. It has good corrosion resistance and is suitable for working in a marine atmosphere. It can manufacture aviation fuel tanks, oil pipes, brackets, etc. Incomplete annealing; 150~300oC. 2~3h, air-cooled; fully annealed: 390~420oC, heat-transparent (0.5h) air-cooled or water-cooled In the annealed state, a solid solution and a ß phase (Al 3Mg 2 ) are formed. In addition, there are Al 3 Fe, Mg 2 Si, and AlMg 2 Mn or AlFeSi compounds in the alloy. Al-Mg alloy with medium magnesium content, not heat-treated. Low strength, high plasticity, and cold deformation increase strength. Good weldability and excellent corrosion resistance. It is suitable for the manufacture of pipes, containers, skeletons, etc., which require high process plasticity and high resistance to corrosion. Fully annealed: 310~335oC, heat-transparent (or 0.5h warm) air-cooled or water-cooled The annealed structure is a solid solution and a ß phase, and there are also impurity phases such as: Al Mg 2 Mn, Mg 2 Si, AlFeSi. Annealing allows uniform, discontinuous precipitation of the ß phase Al-Mg alloy with high magnesium content cannot be heat treated and strengthened. Low strength, good plasticity, good weldability and corrosion resistance. Suitable for manufacturing parts requiring high plasticity, corrosion-resistant medium-loaded welded pipes, liquid containers, etc. Fully annealed: 310~335oC, heat-transparent (or 0.5h warm) air-cooled or water-cooled The annealed structure is a solid solution + ß phase; there are phases such as Al Mg 2 Zn, Mg 2 Si, and AlFeSi. Annealing can avoid the continuous distribution of ß along grain boundaries Al-Mg alloy with high magnesium content cannot be heat treated and strengthened. Good solderability, corrosion resistance, low strength, and cold deformation can increase strength. Suitable for manufacturing medium-loaded components, liquid containers, pipes, etc. Annealing with gold-containing rivets: 270~330oC, 40min, air cooling: wire annealing is similar to LF5  The annealed structure is a solid solution + ß phase, and there are impurity phases such as Mg 2 Si. The Al-Mg alloy with high magnesium content is not heat-treated and has good plasticity, and has excellent corrosion resistance and weldability. Wires are generally made and used as rivets. Incomplete annealing; 150~300oC, 2~3h, air cooling;           Complete annealing: 390~420oC, heat penetration (insulation 0.5h), air or water cooling The unbalanced structure is: a solid solution, Al 12 Mn, Al 6 Mn, and Al 4 Mn. The annealed structure is: a+ Al 6 Mn, and there are also impurity phases such as: (MnFe)Al 6 , AlMnFeSi, etc. The Al-Mg alloy which cannot be heat-treated and strengthened has low strength and high plasticity, and the cold deformation can strengthen the alloy, and the alloy has excellent weldability and corrosion resistance. Can be made into thin plates, rods, tubes, wires, profiles and forgings, widely used in the manufacture of aviation fuel tanks, tubing, cold stampings, rivets and parts with low force LB733 Complete annealing: 390~420oC, 1h, slow cooling to 200oC, air cooling; intermediate annealing: 320~350oC, 1~2h, air cooling; solution treatment + artificial aging: 460±5oC, 20~40min, water cooling, artificial aging (double Level aging) First level, 70~90oC, 10~20h second level, 150±5oC, 10~20h  The main strengthening phase in solution treatment and artificial aging is ŋ (flaky) with a diameter of 4~6nm; there is still a dispersion phase E containing Cr (Al 18 Cr 2 Mg 3 ), and the impurity phase is Fe 4 Al 13 And Al+Fe+Si phase. Phase grain boundary precipitates ŋ Belonging to resist high strength Al + Zn + Mg-based aluminum alloy heat treatable structure strengthened. Its high strength (compared to LY12), good fracture toughness, high plasticity, low cylinder port sensitivity, excellent corrosion resistance to seawater and marine atmosphere, no intergranular corrosion, exfoliation corrosion and stress corrosion tendency, good weldability; suitable for manufacturing The skin and structural parts of the seaplane have good performance. It can also be used to make other high-strength, anti-corrosion components and sheet metal parts. It can be used in a wide range of applications and can replace LY12.
