AL 3A21 aluminum coil is an alloy with very good corrosion resistance and moderate strength. Excellent weldability, formability, with good machinability makes 3104 aluminium sheet, coil and tread plate is popular and economical choice in Appliance Components. Alloy 3A21 can be cold worked to produce tempers with a higher strength but a lower ductility while not heat-treated or used in casting. It is commonly rolled and extruded as aluminum sheet and foils which in different applications such as truck and trailer roofing, cooking utensils, pressure vessels, refrigerator panels, gasoline tanks, heat exchanger, furniture components.
