  • Publication number: 20160288270
    Abstract: A method for producing brazing preforms including the steps of providing an iron-, iron and chromium-, nickel- or cobalt-based spherical brazing powder. Converting the brazing powder into an agglomerated coarser powder suitable to be compacted into desired preforms and ejecting the preforms from the compaction die, the preforms having integrity and strength enough to let them be handled in an automated brazing line. Optionally, after ejecting from the compaction die, the preforms may be heat treated or subjecting to a sintering process if higher strength is desired. Also, the preform per se and a brazing process utilising the brazing preform.

  • Publication number: 20150093280
    Abstract: A material which can be used to manufacture components which exhibit high strength and high wear resistance, at the same time possessing reasonable ductility. The material also has cost advantages compared to other potential metal powder solutions. An iron based powder composition which achieves desired microstructure/properties and associated sliding wear resistance with reduced content of expensive alloying ingredients such as admixed elemental Ni and Copper.

  • Patent number: 7300488
    Abstract: The present invention concerns a powder metal composition for producing powder metal components comprising a Co-based pre-alloyed powder, with irregularly shaped particles comprising at least 15% by weight Cr and less than 0.3% by weight C, admixed with graphite. The invention also concerns a method for producing PM components by pressing of articles to shape from the powder metal composition according to the invention and sintering them.
