7A09 aluminum alloy is a high -strength aluminum alloy, which is mainly composed of aluminum, zinc, magnesium and copper. This alloy has the characteristics of good mechanical properties, corrosion resistance and weldability, and is one of the commonly used materials in the fields of aerospace, weapons and equipment.

Chalco can produce 7A09 aluminum alloy in ASTM B209, ASTM B210, ASTM B308, ASTM B241, GB/T 3190-2010, GB/T 3880.1-2012. It can meet parameters such as chemical composition, physical performance, size deviation, and surface treatment required by standard requirements.

The semi-finished products of 7A09 alloy are 7A09 aluminum alloy sheet round bar forgings.The alloy has satisfactory fracture toughness in T6 state. The strength and yield strength in T73 over aging state are lower than that in T6 state, but the alloy has excellent stress corrosion resistance and high fracture toughness. The T6 state material has good resistance to exfoliation and corrosion. When the temperature rises, the strength of the alloy decreases, and the long-term use temperature should not exceed 125 ℃.

7A09 7075(American) At present,7A09 aluminum alloy sheet round bar forgings
is one of the most powerful domestic aluminum alloys, which can produce various specifications of plate, bar, profile, thick pipe fittings and forgings. There are four heat treatment states of T6, T73, T76 and T74. The chemical composition is better than that of 7A04 alloy, and its comprehensive properties are better. Under the condition of annealing or solid solution heat treatment, it has good forming properties at normal temperature. The forming performance is lower in the solid solution heat treatment and artificial aging condition, but with the increase of temperature, the forming properties are improved. Resistance welding can be carried out, and it is not suitable for welding.
