What is aluminum round bar?

An aluminum round bar/rod is a solid cylindrical rod made from pure aluminum or aluminum alloys, manufactured by extrusion or casting. It is valued for its light weight, high strength-to-weight ratio, corrosion resistance, and excellent machinability. Aluminum round bars are commonly used in mechanical components, shafts, pins, fasteners, structural parts, and decorative applications. They are available in various alloys such as 1050, 3003, 5052, 6061, and 7075, with diameters ranging from a few millimeters to over 300 mm. Standard tempers include O, H12, H14, T6, and T651, and surface finishes can be mill finish, polished, brushed, sandblasted, or anodized. These bars are produced to meet standards like ASTM B221 and GB/T, ensuring consistent quality for industrial, construction, and engineering uses.View more stock specifications of aluminum round bars
