Abstract

A new iron-based powder containing a plurality of composite particles composed of a ferritic iron or iron-based porous 5 structural particles having at least one particulate friction modifier distributed in the pores and cavities of the structural particles and further containing at least one particulate stabilizer-sealer. The composite particle is especially suited to be used as a functional material in friction formulations such as brake pads and enable replacement of copper or copper-based materials used in such friction 10 material formulations.
