ABSTRACT:
Iron-based metallurgical powder compositions are produced by mixing iron-based powder with an improved binder/lubricant that comprises dibasic organic acid and one or more additional components such as solid polyethers, liquid polyethers, and acrylic resin. These novel binder/lubricants impart one or more enhanced green properties to the powder compositions and reduce the ejection force required to remove the compositions from molds and dies.
