1050 aluminum sheet and strip is a product in the pure aluminum sheet series, with chemical composition and mechanical properties similar to those of the 1060 series products. It is basically replaced by 1060 aluminum sheet and strip in applications. The last two Arabic numerals of the 1050 series are 50. According to international brand naming principles, products with an aluminum content of 99.5% or higher are considered qualified. The technical standard for aluminum alloys in China (GB/T3880-2006) also clearly stipulates that the aluminum content of 1050 should reach 99.5%. Due to the absence of other technical elements, the production process is relatively simple and the price is relatively cheap, making it the most commonly used series in conventional industries. Industrial pure aluminum has the characteristics of high plasticity, corrosion resistance, good conductivity and thermal conductivity, but its strength is low, it is not strengthened through heat treatment, and its cutting ability is poor. Contact welding and gas welding are acceptable.
