Factors to be considered in purchasing aluminium sheets

Writer:Admin   Time:
    When you need to buy aluminium sheet to meet your requirement,some factors must should to be considered.
    Hardness of aluminum sheet plate: Hardness is directly related to the chemical composition of the alloy. Secondly, different states also have great influence. From the maximum hardness, 7, 2, 4, 6, 5, 3 and 1 series aluminum decrease in turn.
    Strength of aluminium sheet: When purchasing aluminium sheet is used as component, appropriate alloy should be selected according to the pressure it bears. The strength of pure aluminium is the lowest, while the hardness of 2-Series and 7-series heat-treated aluminium sheets is the highest, and there is a certain correlation between hardness and strength.
    Corrosion resistance of aluminium sheet: Corrosion resistance includes chemical corrosion, stress corrosion resistance and other properties. Generally speaking, the corrosion resistance of series 1000 series pure aluminium sheet is the best, and that of 5000 series aluminum is good, followed by 3xxx and 6xxx series, and that of series 2xxx and 7xxx seriesis poor. The selection principle of corrosion resistance should be based on its application situation. When using high strength alloy in corrosive environment, it is necessary to use various anti-corrosive composite materials.
    Machinability of sublimation metal sheet/sheets: Machinability, Inclusion Formability and Cutting Performance. Because the formability is related to the state, the strength range of various states should be considered after selecting the aluminium plate number. Usually, materials with high strength are not easy to form. aluminium sheet bending, stretching and deep drawing of aluminium materials are needed, the formability of annealed materials is the best, and vice versa, the formability of heat treated materials is the worst. The cutting property of aluminium sheet is poor. For dies, mechanical parts and other products which need to be machined, the machinability of aluminium sheet is an important factor to be considered. On the contrary, the machinability of low strength products is poor. For dies, mechanical parts and other aluminium products which need to be machined, the machinability of aluminium sheet cladding is an important consideration.
