    摘要： An extrusion process for forming consumable anodes and the product produced therein. The process comprises the co-extrusion of a wire core having a non-ferrous light metal surface with an overcoating of a dissimilar light metal. A synthetically produced non-ferrous metal oxide layer is interposed between the dissimilar light metal surfaces to reduce the incidence of core wire breakage during extrusion operations. It is believed that alloying of the light metal core surface with the dissimilar extruded overcoating is inhibited by the oxide layer, thereby substantially eliminating adherence of a low melting, non-ferrous alloy to the extrusion die. Breakage of the core wire during extrusion is thereby minimized.

    摘要： A continuous process for cladding a metal core rod with a dissimilar metal sheath. Contaminants are removed from the periphery of a moving length of core rod. While the core rod is maintained contaminant-free, a thin annular sheath of cladding metal is extrusion bonded around the periphery of the core rod to produce a clad rod suitable for subsequent drawing into wire without the need for sintering, metal removal or other finishing operations on the clad rod.

    摘要： The current invention is directed to a cost effective method of manufacturing bullets or projectiles for firearms which are identifiable after firing and undergoing damage. The mass production of low cost ammunition makes adoption of a requirement that projectiles be so identifiable unlikely unless manufacturing methods and costs are not substantially disrupted.The method envisioned produces projectile bodies from rod or wire stock by encasing identification tag material, and swaging a projectile body with a wholly or partially encased tag with indicia. The stock may be extruded around premade identification tags or a recess may be reverse extruded in each slug. The tags may have repeated indicia in each projectile and some indicia may be accessible from the outside of a completed round of ammunition. The swaging process retains the identification tags which are protected by the body of the projectile for recovery after the projectile is used.

    摘要： A method of making a steel core brass stair rod includes placing a brass billet into a chamber of an extrusion apparatus, where the brass billet includes an aperture configured to receive a steel core. The brass billet is heated to a temperature at which the brass billet is pliable. The brass billet and the steel core are co-extruded through a die of the extrusion apparatus such that the brass billet forms a brass shell which is fused to the steel core, where there is no air gap between the brass shell and the steel core.

    摘要： A method of manufacturing a clad product in which a metallic substrate material is extruded and a cladding material is then brought into intimate contact with the heated extrudate before the extrudate has had an opportunity to cool to room temperature. The cladding material is compressed against the heated extrudate, thereby bonding the cladding material to the substrate material and forming the clad extruded metallic product. The clad extruded metallic product is then cooled to room temperature.

    摘要： An extrusion process is described where a reinforcing element is fed into an extrusion matrix while the reinforcing element is under sufficient tension to elastically elongate the reinforcing element. When the extruded matrix is hardened (e.g., by cooling after extrusion), the reinforcing element remains inserted within the body of the extruded article in a pre-stressed form. A reinforced extruded article according to the present invention includes the extruded material and at least one embedded element under elongated tension. In a preferred embodiment of the invention, the embedded element has a higher tensile than that of the extruded material. The reinforcing member is able to elastically stretch or lengthen under a load. A preferred embodiment of the invention uses wire rope (twined, braided, cabled, woven, non-woven, or mixtures thereof) with different, varying or larger angles (as with larger helix angles) to give the extruded material a larger surface area with which to grip the extrusion. The individual fibers of the reinforcing element or only those fibers on the surface of the reinforcing element may have texturing or microtexturing on the exposed surface to grip into the matrix more strongly by mechanical means.
