ABSTRACT:
The present invention provides a composition for use in pressed powder metallurgy. The composition includes a plurality of substantially dry, discrete agglomerates, a portion of which include a first metal particle adhered to a second metal particle by a binder that includes a polysaccharide. The composition can be used to form green compacts that exhibit excellent green strength and high density. The present invention also provides a process for the preparation of the composition, a method of forming a metal part using the composition and metal parts formed according to the method.
