Patent number: 8590356Abstract: A method, for the production of profiles (16) of a light metal material, in particular a magnesium material, by means of extrusion with a hydrostatic extrusion device (10), is disclosed. A volume of material (15) is pressed through a die (14), having the form of the desired profile (16) in order to form the profile (16). A grain refiner is added to the light metal material to form the material volume (15) used in the extrusion process.Type: GrantFiled: March 3, 2005Date of Patent: November 26, 2013Assignee: Helmholtz-Zentrum Geesthacht Zentrum für Material- und Küstenforschung GmbHInventors: Karl Ulrich Kainer, Jan Bohlen, Piet-Jan Vet, Pieter Hoogendam, Luud Meijer, Wim Sillekens, Jan Schade Van Westrum

Patent number: 7383713Abstract: Method of manufacturing consumable filler metal wire, rod, or stick, and the like, of predetermined length and cross-section for use in welding, including: providing an ingot of a first metal and one or more different further metals; forming composite product by providing the ingot of the first metal with one or more hollow cores in substantially parallel relation to each other and locating in the hollow cores the different further metal or metals; applying pressure to the composite product to reduce its cross-section to a predetermined cross-section to form feedstock. Optionally further deforming the feedstock by mechanical pressure to form wire, rod or stick, of final cross-section so ultimate alloying of the first metal with the different further metal or metals occurs when the wire, rod or stick is used as filler material or consumable electrode during welding. Using this filler metal for welding an assembly of aluminium members.Type: GrantFiled: March 17, 2006Date of Patent: June 10, 2008Assignee: Aleris Aluminum Koblenz GmbHInventor: Huibrecht Adriaan Wouters

Patent number: 6258465Abstract: Provided is an energy absorbing member which makes it possible to induce contraction and deformation into a form of bellows, with Euler's buckle being restrained. An energy absorbing member comprises a hollow extrusion which is made of an aluminum alloy and has an outer portion and an inner rib connected to the outer portion, and the radius of the corner where the rib and the outer portion are connected to each other is not more than a half of the thickness of the rib. A similar energy absorbing member has plural inner ribs which are connected to the outer portion and cross each other, and the radius of the corner where the ribs cross each other is 1 mm or less.Type: GrantFiled: July 8, 1998Date of Patent: July 10, 2001Assignee: Kabushiki Kaisha Kobe Seiko ShoInventors: Takashi Oka, Hiroyuki Yamashita, Masakazu Hirano

Patent number: 5853553Abstract: A sacrificial anode and method of making a sacrificial anode are provided. The anode includes an extruded galvanically active metal rod and integrally formed end cap which has a cylindrically shaped portion with a threaded exterior surface. The anode is formed by extruding the rod, forging the end cap from the anchoring end portion of the rod, and machining the outer surface of the end cap to provide threads.Type: GrantFiled: January 5, 1998Date of Patent: December 29, 1998Assignee: Alumax Extrusions, Inc.Inventor: Richard Twigg

Patent number: 5740688Abstract: An apparatus and method for the forming of a shaped article includes a means for plasticizing a feed material; a die chamber; a means for delivering a plasticized feed material from the plasticizing means and into the die chamber, the delivery means in flow communication with the plasticizing means and the die chamber; and means for applying a pressure to a material in the die chamber. In operation, a feed material is introduced into a plasticizing source; the plasticized feed material is delivered to a die chamber connectable in flow communication with the plasticizing source; and supplemental pressure is applied to the plasticized feed material within the die chamber.Type: GrantFiled: October 5, 1995Date of Patent: April 21, 1998Assignee: Sural TechInventors: Navtej S. Saluja, Alfredo Riviere V.
