Abstract: A method of metal injection molding on an injection molding machine having a heated barrel with an increasing temperature gradient is disclosed. A first step includes providing a metal alloy feedstock including a first component having a first melting point and a second component having a second melting point that is higher than the first melting point, the first melting point and the second melting point selected to match the temperature gradient of the heated barrel of the injection molding machine. A second step includes feeding the metal alloy feedstock into the injection molding machine. A third step includes melting the metal alloy feedstock within the heated barrel of the injection molding machine. A fourth step includes maintaining the percentage of solids to liquids in the metal alloy feedstock of the first component and second component within a processable range of about 5% to about 30%.

Abstract: A metal alloy feedstock and method for metal injection molding is disclosed. The alloy includes at least two components, such as a first component and a second component. The first component has a first melting point and the second component has a second melting point higher than the first melting point. The first melting point and the second melting point match to the temperature gradient of the heated barrel of an injection molding machine whereby when fed into the injection molding machine the first component melts prior to the second component melts and enables the second component to solute into the first component. Additional components may also be used.
