Air certificate 7XXX 7050 7075 aluminum plate sheet Mg-Cu), 7XXX (Al-Zn-Mg-Cu), 6XXX (Al-Mg-Si) and Al-Li alloys; the products are rolled sheet, extruded parts and forgings. 2XXX alloy is mainly based on its good damage tolerance performance, 7XXX alloy is mainly based on high strength and resistance to stress corrosion. The application of these two series of Li alloy alloy in the largest amount of aircraft. 6XXX and Al-T78 alloy to replace 2024 in recent years has also increased, such as the use of 6056-gold
Commercial aircraft Air certificate 7XXX 7050 7075 aluminum plate used on the more advanced aluminum alloy are 2324-T3, 7150-T77, 7055-T77 and 7085-T76, etc., this T39,2524-some alloys with high strength, high toughness, anti-fatigue and corrosion resistance and other good Comprehensive performance.
Air certificate 7XXX 7050 7075 aluminum plate In order to improve the competitiveness of aluminum, people in the previous alloy based on the development of some new alloy, with better performance, such as 101.6 ~ T7651 thick plate than 7050 has a high strength; 254mm 7140-2139-T8XX plate thickness can be 2050-T8 sheet,
the thickness of up to 152.4mm, in 2XXX-T7451, and the lower density, strength, toughness, fatigue performance is better than 7050-crack resistance and heat resistance increased , Replace 7050 alloy can reduce 5%; 2198-T8X with high strength, high damage tolerance and high thermal stability, high forming and welding Air certificate 7XXX 7050 7075 aluminum plate
