Abstract
The present invention presents a method of processing ferrous powder materials to produce high strength small component parts suitable for use in miniaturized electrical and electronic equipment. The processing steps involve, in part, mixing with a binder, dewaxing or presintering at a temperature higher than in the conventional dewaxing process, and final sintering at a temperature lower than the conventional sintering process to produce parts having density values of over 96% theoretical density and high mechanical strength properties in a shorter sintering time than the conventional processing method.
