Drawn aluminium bars - Import export

On request, we can supply aluminium alloys in the form of rod or bar. These are available in most of the commercially available aluminium alloys. The tolerances of extruded aluminium rods and bars can also be further improved by subsequent drawing. In recent years, ALUnna has specialised in the production of rod and bar meeting the highest quality standards. If you require a specific delivery option for rod or bar such as special testing then we will definitely find a solution for you.

Depending on the application, tubes may require subsequent drawing following the extrusion process. Examples of this are: a requirement for a high degree of dimensional control and/or the need for tight tolerances, where the final outside diameter and/or wall thickness of the extruded tubes can only be achieved by subsequent cold drawing, where the final mechanical properties for non-heat treatable alloys are to be achieved by strain hardening (drawing) or where special requirements exist for the microstructure of the tubes.

Drawing is a process of cold metal forming, in which the processed material moves through a suitably shaped hole that is a special tool called a drawing die. The aim of drawing is obtaining products in the form of bars or wire with very precise cross-sectional dimen - sions, smooth, bright surface and specific mechanical properties. As a result of the drawing process material is strengthened which means increase in strength proper - ties and decrease in plastic properties.
