Abstract (en)

[origin: WO03018225A1] The invention relates to a method for producing elongate-shaped elements, such as wires, rods and pipes made of magnesium or magnesium alloys by slip-type drawing at room temperature. The aim of the invention is to develop a method which enables magnesium wires, rods and pipes to be produced by cold-drawing. According to said a method, this is achieved by subjecting the materials to surface treatment before the deformation thereof, guaranteeing a surface roughness which is as low as possible, the value of the average surface roughness being Rz < 12 mu m. The cold-adherent is carried out by using solid-adherent lubricant coatings on the deformation items.
