1100 is industrial pure aluminum, the aluminum content (mass fraction) is 99.00%, and it can not be heat-treated. It has high corrosion resistance, electrical conductivity and thermal conductivity, its density is small, plasticity is good, and various aluminum materials can be produced by pressure processing, but the strength is low. Other process performances are basically the same as 1050A. 1100 is usually used for good forming and processing properties, high corrosion resistance, and does not require high strength, such as food and chemical handling and storage equipment, sheet metal products, hollow hardware for rolling and rolling, and welding combination keys. , reflectors, nameplates, etc.
1100 aluminum strip is a series of pure aluminum sheets, its strength is relatively low, with excellent ductility, formability, weldability and corrosion resistance; after anodizing, it can further improve the corrosion resistance and at the same time obtain an aesthetic surface; .
The pure aluminum plate series determines the minimum aluminum content of the series based on the last two Arabic numerals. For example, the last two Arabic numerals of the 1100 series are 00. According to the international brand nomenclature, the aluminum content must reach 99.00% above the qualified product. China's aluminum alloy technical standards (GB/T3880-2012) also clearly stipulates that 1100 aluminum content reached 99.0%.
