Aluminum knowledge. What is the model 3003 H24? What does H mean?
H: work hardening state.(1) Hxx state:H1 * - hot rolling, Zhang Liqiang; H2 * - continuous casting and rolling, Zhang Liqiang, part of the toughening; H3 * - after stress treatment, stable performance; H4 * - after paint or coating; H x 2 - 25% x 4 - H hardness; hardness 50% processing; H * 6 - 75% hardness; H * 8 - 90 more than the hardness.(2) Hxxx state:H111: suitable for the final annealing, but also a proper amount of work hardening, but the degree of hardening is not as good as the H11 state of the product.H112: for hot forming products, the mechanical properties of the condition are specified.H116: made for magnesium content more than 4% 5 * * * alloy products. These products have specified mechanical properties and anti stripping corrosion resistance requirements.
According to the main alloy aluminum alloy elements can be divided into 2 * * * for Al Cu alloy aluminum (Al--Cu), 3 * * * aluminum manganese alloy aluminum (Al--Mn), 4 * * * series of aluminum silicon alloy aluminum (Al--Si), 5 * * * for aluminium magnesium alloy aluminum (Al--Mg). 6 * * * for Al Mg Si alloy aluminum (AL--Mg--Si), 7 * * * for aluminum and zinc alloy aluminum [AL--Zn--Mg-- (Cu)].
3003 is aluminium manganese alloy aluminum plate (Al--Mn), which is mainly composed of manganese.H24: continuous casting, continuous rolling, Zhang Liqiang and partial toughening.Is the aluminum plate with a thickness of more than 0.2mm to 500mm, 200mm width, length less than 16m aluminum material called aluminum plate or aluminum sheet, aluminum is below 0.2mm, 200mm within the width of the row material or bar (of course, with the progress of the large equipment, the width can be 600mm row material also more). Aluminum sheet refers to the rectangular plate made of aluminium ingot rolled and divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, middle thick aluminum plate and pattern aluminum plate.Aluminium alloy is added in the process of aluminum alloy elements (main alloying elements copper, silicon, magnesium, zinc, manganese, minor alloying elements such as nickel, iron, chromium, titanium, lithium, etc.) in order to improve the mechanical properties of aluminum and chemical index. Alloy aluminum sheet has some special properties of pure aluminum plate, and is widely used in special environment, such as ship, refrigerator, mould, aerospace equipment, etc..
