Commercially pure aluminum Overview
Commercially pure aluminum refers to 1xxx series aluminum alloys with aluminum purity generally above 99%, including 1050 aluminum, 1060 aluminum, 1070 aluminum and 1100 aluminum. These materials are widely used where excellent corrosion resistance, high ductility, good thermal conductivity, electrical conductivity and deep drawing performance are required. Compared with structural aluminum alloys, commercially pure aluminum is softer and non-heat-treatable, but it provides superior formability and surface quality for industrial processing.
Xi'an Dongmeng Group Co., Ltd supplies commercially pure aluminum in sheet, plate, coil, strip, foil and bar forms for global B2B buyers. The 1xxx series aluminum family is ideal for electrical components, chemical equipment, heat exchangers, packaging materials, reflective panels, cookware, nameplates and industrial fabrication.
