Aluminium and aluminium alloys are very suitable for extrusion and many types of tubes can be produced from easily extrudable aluminium and aluminium alloys
Extruded tube is a specific form of hollow extrusion, though not termed as a hollow “profile,” that is, long in comparison to its cross-sectional size.Continue extruded tube is symmetrical with uniform wall thickness and is either round, elliptical, square, rectangular, hexagonal, or octagonal. Square extruded tube, rectangular tube, hexagonal tube, and octagonal tube may have either sharp or rounded corners.
