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. Alternatively, a powdered metal component is disclosed having areas of different densities.
