Product introduction

　　3003 / 3A21 (corresponding to the old brand LF21) aluminum coil is Al-Mn alloy, which is the most widely used antirust aluminum and can not be strengthened by heat treatment, so cold working method is adopted to improve its mechanical properties; it has high plasticity in annealing state, good plasticity in semi cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability and poor machinability. The products are mainly used in cell phone battery shell material, lighting, interior decoration, air conditioning pipe, automobile oil tank, tank, electrolytic capacitor and other fields.
