Applications of 1100 class aluminum

1100 aluminum plate is mostly used for some parts which require good forming and processing properties, high anti-corrosion, but low strength, such as video, the transportation and storage equipments of chemical products, metal sheet products, the processing of drawing spinning hollow goods, welding key combination, reflector and nameplat, etc. 1100 aluminum plate is widely used in various fields from cooking utensils to industrial equipment, such as heat sinks, caps, printing sheets, building materials, heat exchanger components, reflective devices, pipe, storage, bottle caps etc. it can also be used as deep-draw stamping products.
