  • Publication number: 20070187462
    Abstract: The present invention relates to a method of manufacturing a shaped product by means of brazing. The method includes the steps of: producing an intermediate object of metal by rolling or extrusion and having at least one flat surface, coating the at least one surface with a brazing composition comprising a resin, a wax, and a flux and/or flux-producing compound, reshaping the intermediate object into a shaped product, and heating the shaped product to a temperature sufficient to provide at least one brazed connection between defined parts of the shaped product. When a brazing composition is used in this method, it is not necessary to use an additional lubricant during deforming.

  • Publication number: 20070151697
    Abstract: Abstract A preform of a foamable laminate sheet including a core between two metal skin plates, said core comprising a foaming agent and a foamable metal. The foamable metal includes at least one foamable metal sheet. The foaming agent is applied on at least one side of at least one foamable metal sheet.

  • Publication number: 20070122648
    Abstract: A multi-layered brazing sheet with improved long life corrosion resistance achieved by balancing the Zn, Cu, Mn, Si and Mg content of the core and interliner alloy. The brazing sheet has a core of a 3xxx alloy, an inner braze cladding of a 4xxx alloy, and between core and inner braze cladding an interliner of a 3xxx alloy. The 3xxx alloy of the core has 0.55-1.0 wt % Cu, 0.7-1.8 wt % Mn, <0.3 wt % Mg, <0.4 wt % Zn. The 3xxx alloy of the interliner has <0.25 wt % Cu, 0.5-1.5 wt % Mn, <0.3 wt % Mg, 0.1-5.0 wt % Zn. A 1xxx or 7xxx alloy could be used for the interliner instead of the 3xxx alloy.

  • Publication number: 20060157352
    Abstract: Disclosed is a method of applying a metal layer onto at least one surface of an aluminium or aluminium alloy workpiece, including the steps of pre-treating the surface by cathodic activation in a pre-treatment bath containing sulphuric acid and metal-ions selected from the group consisting of nickel, iron and cobalt, and applying a metal layer by electroplating the pre-treated workpiece. The metal layer is selected from the group consisting of nickel, iron, cobalt, and alloys thereof.

  • Publication number: 20060121306
    Abstract: The invention relates to a brazing sheet product comprising a core sheet, a clad layer on said core sheet made of an aluminum alloy containing silicon in an amount in the range of 4 to 14% by weight, an optional layer comprising nickel on the outersurface of said clad layer, and a diffusion layer comprising nickel-tin alloy on the outer surface of said nickel layer. The invention further relates to a method of manufacturing such a brazing product comprising the process step of plating different metal layers and subjecting the plated brazing product to an annealing treatment by holding the plated brazing product at a temperature in the range of 100 to 500° C. for a period of 1 sec. to 300 minutes to form a diffusion layer comprising nickel-tin alloy on the outer surface of said layer comprising nickel.

  • Publication number: 20050022841
    Abstract: Method of de-coating metallic coated scrap pieces, the metallic coated scrap pieces comprising a metallic core layer and a metallic coating layer of which the liquidus temperature of the metallic coating layer is lower than the solidus temperature of the metallic core layer, such as brazing sheet scrap pieces, or from metallic coated scrap pieces (7) of which the upper part of the melting range of the metallic core layer, wherein the metallic coating layer is at least partially removed from the metallic core layer of said scrap pieces (7) by agitating the scrap pieces (7) at an elevated temperature T above the solidus temperature of the metallic coating layer and below the liquidus temperature of the metallic core layer, together with abrading particles, characterised in that the abrading particles are brought into fluidisation during the agitating of the metallic coated scrap pieces (7), thereby forming a fluidised bed (15).
