Aluminum alloy has been widely used in various industrial sectors because of its small specific gravity, high specific strength and stiffness. Aluminum alloy forgings have become an indispensable material for mechanical parts of various industrial sectors. All kinds of forgings that can be forged with low carbon steel can be forged by aluminum alloy. Aluminum alloy can be forged on various forging equipment such as hammer, mechanical press, hydraulic press, upset forging machine, reaming machine, etc. It can be forged freely, die forging, upset, roll forging and reaming. Generally speaking, aluminum forgings with small size, simple shape and less strict deviation requirements can be easily forged on the forging hammer. However, for aluminum forgings with large specifications and severe deformation requirements, water (liquid) press is suitable for forging. For large and complex aluminum forgings with integral structure, it is not necessary to use large die forging hydraulic press. Especially in the past ten years, with the development of science and technology and national economy, higher and higher requirements for materials have been put forward, forcing aluminum alloy forgings to develop towards large-scale integration, high strength, high toughness, complex and precision direction, greatly promoting the development of large and medium-sized hydraulic press.
7075 of the main alloying elements are zinc, with strong strength, good mechanical properties and anodic reaction. Mainly used for manufacturing aircraft structures and other high-stress structural components with high strength and corrosion resistance, such as aircraft upper, lower wing panels, trusses, etc. Good plasticity after solution treatment, heat treatment and strengthening effect, good strength below 150 degrees, and especially good low-temperature strength, poor welding performance, stress corrosion. Corrosion cracking tendency, also widely used in mold processing, mechanical equipment, tooling and fixture.
The 7075 aluminum alloy forging pipe can be used in the South Aluminum Industry of Kunshan Shanxi Province. It can have one or more closed through holes with uniform wall thickness and cross-section, and can be delivered in a straight line or in coils. Widely used in automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electrical and mechanical, household and other industries.
