  • Patent number: 5903815
    Abstract: A product and method are disclosed for constructing a powdered metal component from two or more discreet powdered metals in which one or more of the powdered metals is weldable following compaction while the other powdered metal is not A die having two die parts which together define a die cavity therebetween corresponding in shape to the desired metal component is first partially filled with one of the powdered metals and the remainder of the die cavity is then filled with the other powdered metal. The die parts are then compressed together to form the pressed component which, after removal from the die, is sintered. The weldable powdered metal is either powdered iron or powdered steel having a carbon content less than about 0.6% by weight carbon. Conversely, the other powdered metal is powdered steel or iron or alloyed, or mixtures thereof, having a carbon content typically greater than 0.6% by weight for enhanced hardness of the part.

  • Patent number: 5328773
    Abstract: An article of manufacture is disclosed having a first part constructed or powdered metal and having a lip which extends outwardly from one end of the first part. A second part, for example a steel stamping, has a first side, a second side and an opening extending between its sides. The opening is dimensioned so that, with the second part positioned on the end of the first part, the lip extends through the opening and outwardly from the second or outer side of the second part. The first and second parts are then mechanically secured together by deforming the lip so that a portion of lip overlies and entraps an edge portion of the second part between the deformed lip and the end of the first part.
