Pure aluminum plate sheets roll have low strength, but with excellent formability, surface treatment, weldability, corrosion resistance. The 1050 aluminum veneer strip is also part of the pure aluminum plate sheet roll and comes close to the chemical composition and mechanical properties of the 1060 series, which is now largely replaced by a veneer sheet of 1060 aluminum. 1050 series of the last two digits of 50, according to the international nomenclature of nomenclature, aluminum content must reach more than 99.5% for the qualified products. China's aluminum alloy technical standards (GB / T3880-2006) also clearly stipulates that 1050 aluminum content reached 99.5%. Because it does not contain other technical elements, so the production process is relatively simple, the price is relatively cheap, is currently the most commonly used conventional in industry .
