Aluminum tube is a kind of nonferrous metal tube, which refers to the metal tubular material extruded from pure aluminum or aluminum alloy to be hollow along its longitudinal full length.
According to the shape, it can be divided into square pipe, round pipe, riffled pipe, profiled pipe and universal aluminum pipe.
It can be divided into seamless aluminum tube and ordinary extruded tube according to extrusion mode
The alloy aluminum tube profile is mainly produced by the extrusion method, the most commonly used extrusion processes are forward extrusion and reverse extrusion. Extruded alloy aluminum pipes and profiles adopt the production process of ingot heating-extrusion-finishing; for heat-treated aluminum alloys that can be strengthened, quenching and aging treatment are also required.
