Abstract

In the first stage, a cast bar is extruded to make a blank. The deformation ratio exceeds 1 : 20. For this stage, the microstructure of the material transversely to the direction of deformation, is modified to a grain size less than 20 mu m. One of the elements Zn, Mn , Ca, Si, Sb, Ag is added to the magnesium to manufacture the cast bar and/or up to 2 wt% Zr is added to refine the grain microstructure of the alloy. In the second stage, extrusion billets are produced from the blank; they are taken out at right angles to the direction of extrusion. In the third stage, the billets are extruded transversely to the direction of blank deformation, at room temperature or a temperature no greater than 200[deg] C. No lubricant is used. The shape of the billets is matched with that of the extrusion die, especially at the edges. The equipment used, includes a matrix or die, and a pressing plunger moving relatively to it. The billet alloy has a hexagonal lattice structure. Alternatively, using a temperature below 200[deg] C the wall thickness range is 0.1-13.6 mm, preferably 0,5 mm and less. Independent claims are included for the following: (A) corresponding equipment; (B) and the object produced.
