Plain Aluminum Foil
Aluminum foil is soft, strong, and relatively light, and it is a widely used building material. The general term for aluminum-based alloys.
Aluminum foil has low density but high strength, which is close to or exceeds that of high-quality steel. It is the most widely used non-ferrous metal structural material in industry. The skins, beams, ribs, longitudinal beams, bulkheads and landing gear on the aircraft can all be made of aluminum alloy. The amount of aluminum used in airplanes varies by application. Civil aircraft that pay attention to economic benefits are widely used due to the low price of aluminum alloy.
Military aircraft need good combat performance and relatively reduce the amount of aluminum. For example, the "Aifo 15" high-performance fighter with a maximum flight speed of Mach 2.5 uses only 35.5% aluminum alloy. Some aluminum alloys have good low temperature properties. They are not cold and brittle under -183～-253[2oc], and can work in liquid hydrogen and liquid oxygen environment. They do not chemically react with concentrated nitric acid and asymmetric dimethylhydrazine, and have good performance. Excellent welding performance, a good material for liquid rockets
Usually divided into two categories: cast aluminum foil, which is used in the as-cast state; deformed aluminum foil, which can withstand pressure processing and has higher mechanical properties than the as-cast state. According to the processing method, it can be divided into deformation and casting. The non-heat-treatable strengthened type cannot be improved by heat treatment, and can only be strengthened by cold working deformation. Mainly include high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum, rust-proof aluminum, etc. The aluminum alloy that can be heat-treated and strengthened can improve its mechanical properties through heat treatment methods such as quenching and aging.
Large Wide Roll Of Aluminum Foil The food industry and the pharmaceutical industry have become one of the important markets for aluminum foil
