Aluminum Bar
Aluminum bar rod is a solid cylindrical form of aluminum alloy widely used across industries for its exceptional blend of lightweight properties, corrosion resistance, and mechanical strength. Available in a variety of alloys, tempers, and sizes, aluminum bar serves as a fundamental building block for manufacturing, construction, transportation, and precision engineering.
Aluminum bars are produced through extrusion, rolling, or forging processes, resulting in precise dimensions and excellent surface quality. The choice of alloy determines key properties such as strength, weldability, machinability, and environmental resistance. Common alloys include the 1000, 2000, 3000, 5000, 6000, and 7000 series.
