Abstract: A method is described for obtaining extrusion products of "high performance" alloy wire of small cross section in an economical fashion. The ratio of length to cross section of cast "high performance" alloy preforms limits the length of a filled billet to less than the optimum which may be extruded on available extrusion presses where it is desired to obtain small diameter extrusion products in a single extrusion. This limitation is overcome by squaring the ends of cast lengths of the alloy and then butt welding such lengths to compositely form preforms of the maximum length capable of being extruded on a given extrusion press. The composite preforms are extruded in a filled billet in accordance with the teachings of U.S. Pat. No. 4,209,122. The extrusion products from these composite preforms have the same desirable properties described in that patent and extend the benefits described therein.
