Series 1: Pure aluminum (high content of aluminum), low-cost and single process,as conventional industrial aluminum. 1100 alloy is general industrial pure aluminum with aluminum content of 99.0%. Lower strength but good ductility. Formability, weldability and corrosion resistance; O temper: Low tensile 75-105MPa, high elongation, Suitable for stretching products; H24 temper: Tensile above 110MPa, suitable for Ceiling/curtain wall; H26 temper: Relative to H24, the hardness is higher than 130MPa. Poor bending. Application: Large-scale stadiums, airports, high-speed rail stations and other interior decoration.
