Alloy 3003 is the most common alloy grade in the aluminum-manganese alloy series with a manganese content of about 1.2-1.5%. Therefore, the hardness of 3003 aluminum plate is harder than that of 1000 series aluminum plate.However, the annealing state of the alloy 3003 is also a key point that determines the aluminum sheet hardness. The common tempers of alloy 3003 are H24, H14, H22,H18 and O. H indicates the temper of cold work hardening and the following numbers indicate different degrees and types of cold work hardening.Of them, 3003 H18 is with high hardness while the 3003 O temper aluminum sheet is of low hardness. The 3003 O temper is with the longest annealing time, about 20 hours. Each temper is for meeting different needs.Machinability of the softer tempers O and H12 is poor, with the harder tempers such as H14 and above being somewhat easier to machine. Yet their corrosion resistance and rust proof performance is as excellent as other tempers.3003 O temper aluminum sheet is suitable for stamping, spinning, stretching, etc. For those products requiring stamping and excellent anti-rust performance, 3003 O temper aluminum is an ideal choice.3003-O plain sheet is often further processed into 3003 aluminum tread plate, which is often used in decorative architectural applications, due to its bright reflective finish. It is usually produced in a “1-bar” or “propeller” tread pattern.Alloy 3003 aluminum sheet is often used for the manufacturing of the cooking utensils, decorative trim, awnings, siding, storage tanks and chemical equipment.
