Aluminum alloy is one of he most widely used materials in aviation industry, which is well known for good mechanical properties, high strength, light weight, and good toughness. It is one of the most important members of the civil aircraft structural material.
The high strength aluminum alloys are are mainly used in aircraft fuselage including fuselage/wing skin, fuselage/wing stringers, wing/tail wing ribs, wing/tail wing spars, fuselage bulkheads,etc.
Heat-resistant aluminum alloys are mainly used in aircraft high-temperature area structures, such as engine compartments, air-conditioning system structures, etc. Corrosion-resistant aluminum alloys are mainly used in aircraft kitchens, bathrooms and environmental control system structures.
The main alloy element of 7050 aircraft alloy is Zinc. In addition to 3%-7.5% Zn, with the addition of Mg, it can MgZn2, having significant strengthening effect, which has better heat treatment effect than Al-Zn alloy.
7050 thick aluminum plate belongs to the third generation of the advanced aluminum alloy in the world. It has high strength, high toughness, fatigue resistance and damage resistance. It is an indispensable key material for various key structural parts in the aerospace field. It is able to maintain the overall flatness and non-deformation after asymmetric processing.
Alloy 7050 has high corrosion resistance and maintains strength in wide sections, making it more resistant to fractures than other alloys. It’s commonly used in wing skins and fuselage, especially in military aircraft.

1. It has high resistance to spalling and stress corrosion cracking.
2. It has excellent tensile strength,shear strength, high supporting strength, excellent fracture toughness and fatigue resistance.
3. It is of high strength and excellent welding performance, and low welding crack tendency. It is a high-strength weldable aircraft aluminum alloy sheet.
4. Haomei Aluminum strictly controls the content of the trace element Si to ensure that the content is below 0.3%, so as to ensure the bending performance of 7050 aluminum sheet.
The high-strength aluminum alloy is also the development trend of aviation aluminum alloy materials. Its specifications in aviation aircraft are also very large. 7050 aluminum sheet has been used for the inner wing spar of the aircraft wing, indicating that there are high requirement for aviation aluminum alloy such as high strength, corrosion resistance, high toughness, and high damage tolerance.
