7000 seriya metall alyuminiy qotishmasi mainly contains zinc element. 7075 alyuminiy plastinka stressni engillashtiradi va ishlov berishdan keyin deformatsiyalanmaydi yoki burilmaydi. Hammasi juda katta va qalin 7075 alyuminiy plitalar qum teshiklari va aralashmalar yo'qligiga ishonch hosil qilish uchun ultratovush tekshiruvidan o'tkaziladi. 7075 alyuminiy plitalar yuqori issiqlik o'tkazuvchanligiga ega, which can shorten the molding time and improve work efficiency. The main feature is the hardness of 7075 yuqori qattiqlikdir, yuqori kuchli alyuminiy qotishmasi, commonly used in the manufacture of aircraft.
7075 aluminum plate belongs to Al Zn mg Cu superhard aluminum. 7075 alloy is a strength deformed aluminum alloy which has been used in aircraft manufacturing since the late 1940s and is still widely used in aviation industry. It is characterized by good plasticity after solution treatment, especially good heat treatment strengthening effect, high strength below 150 ℃ and particularly good low temperature strength; Poor welding performance; Stress corrosion cracking tendency; It needs to be coated with aluminum or other protective treatment. Double aging can improve the stress corrosion cracking resistance of the alloy. The plasticity in the annealed and just quenched state is slightly lower than 2A12 in the same state and slightly better than 7A04. The static fatigue, notch sensitivity and stress corrosion resistance of the plate are better than 7A04, especially in the 7075-T651 state. It is known as the product of aluminum alloy, with high strength and far better than mild steel. The alloy has good mechanical properties and anodic reaction. It is a typical aluminum alloy material for aerospace.
