Aluminium pipe

Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and it has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum tubes and aluminum alloy tubes is increasing. The production process of aluminum tubes generally adopts the production process of ingot heating-extrusion-finishing, for heat-treating aluminum alloys that can be strengthened, quenching-aging treatment is also required. For cemented carbide and high-magnesium aluminum alloy pipes, the first production process is extruding the tube blank, cold rolling, and then drawing the finished product.
