ABSTRACT:
This invention presents, inter alia, novel iron-based powder compositions and compacted articles made from the same. The novel iron-based powder compositions of the invention are formulated with a fluoric resin, such as polytetrafluoroethylene, which provides powder mixtures with good flow properties and good uniformity. Compacted articles made from the novel iron-based powder compositions of the invention show reduced core losses and have good magnetic permeability over an extended frequency range. These compacted articles also exhibit high green density and good ejection characteristics.
