Description

Aerospace Aluminium Alloy Plate Sheet

The 7 ××× system alloy is an aluminum alloy with Zn as the main alloy element, which is a heat treatment to strengthen the aluminum alloy. The alloy is Mg, Al-Zn-Mg alloy, alloy has good thermal deformation, quenching range, can get high strength heat treatment in the appropriate conditions, can be welding performance is good, generally have good corrosion resistance, stress corrosion tendency is Aluminum Alloy weldable high strength.

Al-Zn-Mg-Cu alloy is developed by adding Cu in Al-Zn-Mg alloy on the basis of its strength is higher than 2××× series alloys, commonly known as the Aluminum Alloy ultra high strength, the yield strength of the alloy is close to the tensile strength, yield strength and tension strength rate high, strength ratio is very high, but the plastic and high temperature strength is low, should be at room temperature 120ºC below, use of force bearing structure, easy processing, good corrosion resistance and high toughness.

7xxx alloy series, because of its long history and varieties of materials, including sheet metal, aluminum plate, medium plate, heavy plate, forgings and extruded parts, has been series of materials and heat treatment. It has been the most widely used high-strength aluminum alloy. The 7175 alloys developed later are special forged alloys, and 7475 are mainly used in the manufacture of thin plates and thick plates. 7475 alloy is the best alloy in the 7075 series with damage tolerance.
