Animation: Seamless Extrution (direkt)
Seamless aluminium tubes can be ordered in all commercially available aluminium alloys in addition to high strength aluminium alloys which are required for more demanding applications. ALUnna has a number of extrusion presses equipped with mandrel piercing capability. This allows us to extrude a large range of extruded tubular dimensions from a number of different billet diameters. The size range for seamless extruded tubes ranges from 17 mm to 300 mm in diameter.
Tubes with a small outside diameter or thin wall thickness can be produced by a subsequent cold drawing process to achieve the final dimensions and tolerances. The following tables are a guide to the dimensions we offer:
