3003 h26 aluminum coil supplier

　3003 h26 aluminum coil is a regular product of aluminum manganese alloy series, featured by good formability, solubility and corrosion resistance. It contains Silicon Si: 0.60, iron Fe: 0.70, copper Cu: 0.05-0.20, manganese Mn: 1.0-1.5, zinc Zn: 0.10, others: single 0.05 (total 0.15) and aluminum allowance. Due to the adding of manganese element, 3003 has excellent rust proof characteristics, also known as rust proof aluminum alloy. H26 refers to the temper of part annealing to 3 / 4 hard after work hardening, softer than H28 and harder than H24.

3003 H26 aluminum coil has a tensile strength (25 ° C MPa) of 170-210, yield strength (25 ° C MPa) 145, hardness 500kg force 10 mm 40, ball elongation 1.6mm (1 / 16in) 8-16 and thickness maximum shear stress MPa 95. 3003 aluminum coil has good corrosion resistance close to that of industrial pure aluminum. It has good corrosion resistance to atmosphere, fresh water, sea water, food, organic acid, gasoline, neutral inorganic salt solution even in dilute acid. In the cold deformation state, 3003 aluminum alloy has the tendency of exfoliation corrosion. The larger the deformation is, the more serious the exfoliation is. Because of the uneven color after anodizing, anodizing is generally not carried out.

The strength of 3003 aluminium coil is about 10% higher than 1100. The coil has excellent formability, solubility and corrosion resistance, used to process parts with good formability, high corrosion resistance and weldability, or those requires both these properties and work with higher strength than 1xxx series alloy, such as kitchen utensils, food and chemical product processing and storage devices, tanks for transporting liquid products, and various pressure vessels and pipes. It is also commonly used in ships, warships, vehicle materials, automobile and aircraft plate weldments, pressure vessels requiring strict fire protection, refrigeration devices, TV towers, drilling equipment, transportation equipment, missile components, armor, etc.
