The specific application of Chalco 1145 aviation aluminum plate O, H14 H24 temper in aviation parts

1145 aviation aluminum sheet O temper is often used in the manufacture of large structural parts such as aircraft shells, fuselages, and wing surfaces, as well as small parts such as wings and fuselages. In addition, it is also used in the manufacture of bulkheads, dashboards, seats, shelves and other accessories inside aircraft.

The high strength and light weight of the O-temper of 1145 aviation aluminum sheet make it an ideal material for manufacturing aviation components. It is also very resistant to corrosion, able to maintain its performance and appearance in harsh environments. These characteristics make 1145 aviation aluminum sheet O temper widely used in the manufacture of civil and military aircraft.

Production process of Chalco Aluminum alloy 1145 (UNS A91145) sheet plate

Preparation of aluminum ingots: aluminum ingots are raw materials for the production of aluminum plates, and are generally prepared by electrolysis or alumina pyrolysis.

Smelting: heating the aluminum ingot to the melting point, and adding a small amount of alloying elements such as copper and magnesium to improve the strength and hardness of the aluminum plate.

Continuous casting: the molten aluminum is continuously cast into a slab with a thickness of about 200mm through a continuous casting machine.

Rough rolling: the slab is sent to the rough rolling mill, and after several times of rolling, the thickness is gradually reduced to reach the target thickness.

Hot rolling: send the rough-rolled slab into a hot rolling mill for multiple rolling and annealing treatments to achieve ideal mechanical properties and surface quality.

Milling and cutting: milling and cutting the hot-rolled aluminum sheet to make aluminum sheets of different sizes and shapes.

Inspection and packaging: strict inspection and testing are carried out on the aluminum plate to ensure that it meets the standards of the aviation industry, and then it is packaged and shipped.
