  • Iron-based powder
    Patent number: 7662209
    Abstract: The invention concerns a powder composition including an iron or iron based powder and a lubricating amount of an alkylalkoxy or polyetheralkoxy silane, wherein the alkyl or polyether group has between 8 and 30 carbon atoms and the alkoxy group includes 1-3 carbon atoms.
    Type: Grant
    Filed: June 4, 2007
    Date of Patent: February 16, 2010
    Assignee: Höganäs AB
    Inventors: Mikhail Kejzelman, Paul Skoglund, Hilmar Vidarsson, Per Knutsson
  • Method of preparing iron-based components
    Patent number: 7585459
    Abstract: The present invention concerns a process for the preparation of high density green compacts comprising the steps of providing an iron-based powder essentially free from fine particles; optionally mixing said powder with graphite and other additives; uniaxially compacting the powder in a die at a compaction pressure of at least about 800 MPa and ejecting the green body. The invention also concerns the powder used in the method.

  • Iron-based powder
    Patent number: 7153594
    Abstract: The present invention concerns a new ferromagnetic powder composition comprising soft magnetic iron-based core particles wherein the surface of the core particles are surrounded by an insulating inorganic coating, and a lubricating amount of a compound selected from the group consisting of silanes, titanates, aluminates, zirconates, or mixtures thereof. The invention also concerns a process for the preparation of soft magnetic composite materials using the new powder composition.
