Quality 7475 aluminum Cheung Island Direct: 7475 7475 imports of aluminum bar imports of aluminum 7475 aluminum 7475 aluminum 7475 GB Southwest aluminum latest proxy wholesale prices in Shanghai Cheung Island US ALcoa quality aluminum rod, aluminum tube, Sumitomo / Kobe high precision aluminum South Korea Po items alloy aluminum molds for Russia / automobile manufacturing special high quality anodized aluminum rust-proof aluminum alloy high-strength aluminum alloy plate aluminum super-hard aviation precision industrial aluminum. Authoritative quality assurance, special custom specifications acceptable production (with the goods to allot the original material guarantee / Material Laboratory: SGS / ROHS Report) welcome new and old customers call to discuss 021-57887075 undefined 7475 aluminum alloy case of Al-Zn-Mg-Cu based hard aluminum, used in the manufacture of aircraft structures and other requirements of high strength, high corrosion resistance of high stress structural parts, such as aircraft, under the wing facing the wall panels, stringers, bulkheads, etc.; good plasticity after solution treatment, heat strengthened particularly effective at below 150 ℃ high strength, and has particularly good low temperature strength. 7475 aluminum alloy which is characterized by good plasticity after solution treatment, heat strengthened particularly effective at below 150 ℃ high strength, and has particularly good low temperature strength; welding performance is poor; there is a tendency to stress corrosion cracking; subject package aluminum or other protection treatment used in two-stage aging can improve the ability of the alloy resistance to stress corrosion cracking. 7475 aluminum alloy chemical composition: aluminum Al (minimum): margin silicon Si: ≤0.10 iron Fe: ≤0.12 copper Cu: 1.2 ~ 1.9 Mn Mn: ≤0.06 magnesium Mg: 1.9 ~ 2.6 chromium Cr: 0.18 ~ 0.25 Zinc Zn : 5.2 to 6.2 titanium Ti: ≤0.06 7475 Aluminum Properties and Applications: 7475 aluminum alloy, aluminum and aluminum alloy deformed the United States. 7475 belongs to the Al-Zn-Mg-Cu alloy, used in 7475 for the body and not clad aluminum plate, the wing skeleton, stringers, and many others have both high strength clad aluminum but also have high fracture Toughness components. QQ picture 20150404140120_conew1 Alcoa ALCOA alloy material in the industrial market irreplaceable: 1. dense: A unique grain refinement process to ensure, no sand holes trachoma, stripes, bubbles and impurities crack cracks and other undesirable phenomena. 2. stress: a perfect pretension (T651) Process, the complete elimination of internal stress in the processing and force is not easy to warping, cracking and deformation phenomena. 3 tolerances: all products meet the American Society for Testing and Materials (ASTM) and aerospace material specification (AMS) specification 4. processing performance: the chemical composition, strength and hardness deviation minimize processing to prevent the occurrence of "sticky knife" "chipping" and other bad now 5. Uniformity: heat treatment technology excellence, product 300MM thickness (or diameter) or less, strength, hardness 6. stability remained the same: the production processes all computer-controlled, with little human error, incoming copper and aluminum to provide Alcoa Alcoa different batches of the product but also to ensure consistent performance 7. dyed effect: even and shiny surface without streaks or different colors speckled no other phenomenon 8. Anti-corrosion of metals and alloys by significant micro-inspection, with excellent resistance to stress corrosion and exfoliation corrosion resistance performance, long-term use in a variety of media (such as water vapor weak acid and weak base) environment will not produce pits or blackening 9. high temperature: 400 degrees Celsius It will not permanently deform the work environment.
