aluminum round pipe

7 series aluminum alloy is used to manufacture aircraft structures and other high-stress structural parts with high strength and strong corrosion resistance, such as aircraft upper and lower wing wall panels, trusses, partition frames, etc. Good plasticity after solution treatment, heat treatment strengthening effect is particularly good, below 150 °C has high strength, and has a particularly good low temperature strength, poor welding performance, stress corrosion cracking tendency, two-stage aging can improve SCC resistance, for the manufacture of aircraft structures and other high stress structural parts with high strength and strong corrosion resistance, such as aircraft, lower wing wall panels, trusses, partitions, trusses of transportation vehicles, members, containers; large heat exchangers, and components that cannot be solidified after welding It can also be used to manufacture sports equipment such as tennis rackets and softball bats
