1100 is industrial pure aluminum, aluminum content (mass fraction) is 99.00%, can not be strengthened by heat treatment. It has high corrosion resistance, electrical and thermal conductivity, low density, good plasticity, and can be used to produce various kinds of aluminum materials through pressure processing, but with low strength. Other process properties are basically the same as 1050A. 1100 is usually used for the requirements of good forming and processing performance, high corrosion resistance, and does not require high strength missing, such as food and chemical handling and storage equipment, sheet metal work products, with the drawing of goods spinning processing of small hollow hardware, welding keys, reflectors, nameplates and so on.
