Abstract

A METHOD OF MANUFACTURING ALUMINIUM TUBES FOR TELESCOPIC MAST The present invention relates to a method of manufacturing aluminium tubes for telescopic mast in which primarily billets, formed from an aluminium alloy, are subjected to a porthole extrusion process. Following porthole extrusion, the aluminium tubes are further cold drawn for reducing the cross sectional area of the tube, to increases tensile strength, to achieve H11 tolerance, to improve percentage elongation and to achieve better grains orientation. Successively, the tubes are then straightened on straightening machine to achieve straightness and to relieve the stress generated during cold drawing process. Subsequently, the artificial age hardening is carried out at about 165 ? centigrade with a view to achieve the required mechanical properties and dimensional tolerance in resultant products (aluminium tubes) for telescopic mast.
