Aerospace aluminium sheet: 2024 aluminium sheet, 6061 aluminium sheet, 7075 aluminium sheet for sale Haomei

Aerospace aluminium sheet for sale includes 2024 aluminium sheet, 6061 aluminium sheet, 7075 aluminium sheet. What are the differences between them? Now let's learn together!

2024 aluminium sheet is an aluminium alloy of the Al-Cu-Mn system, the main characteristics and scope of application: this is a high strength hard aluminium, can be heat treated and strengthened, in the quenched and just quenched state plasticity is medium, spot welding is good, with gas welding there is a tendency to form intergranular cracks, the alloy in the quenching and cold hardening of its machinability is still good, after annealing machinability is low: corrosion resistance is not high, often using anodic oxidation It is often anodised and painted or coated with aluminium to improve its corrosion resistance. It is mainly used to make various high load parts and components (but not including stampings and forgings) such as aircraft skeleton parts, skins, spacers, wing ribs, wing beams, rivets and other working parts below 150°C.

6061 aluminium sheet is an Al-Mg-Si series aluminium alloy, which is a high quality aluminium alloy produced by heat treatment and pre-stretching process. Although its strength cannot be compared with 2xxx series or 7xxx series, its magnesium and silicon alloy characteristics are many, and it has excellent processing performance, excellent welding characteristics and plating, good corrosion resistance, high toughness and no deformation after processing, dense material without defects and easy to polish, colouring and film. It has excellent characteristics such as easy film application and excellent oxidation effect. In the aerospace field, it is mainly used to make aircraft skins, fuselage frames, beams, rotor blades, propellers, fuel tanks, wall plates and landing gear struts, as well as rocket forging rings and spacecraft wall plates.

7075 aluminium sheet is an Al-Zn-Mg-Cu system aerospace aluminium sheet, a cold treatment forging alloy, high strength, better than soft steel. Common corrosion resistance, good mechanical properties. Zn is the main alloying element in 7075 and the addition of magnesium to an alloy containing 3%-7.5% zinc results in the formation of MgZn2, which has a significant strengthening effect and makes the alloy far superior to Al-Zn binary alloys in terms of heat treatment. By increasing the zinc and magnesium content of the alloy, the tensile strength will be further improved, but its resistance to stress corrosion and spalling corrosion will then be reduced.
