  • Patent number: 7686894
    Abstract: A magnetically soft powder composite material is described, which is composed of at least 99.4 wt. % of a pure iron powder, a phosphatized iron powder, or an iron alloy powder and 0.05 wt. % to 0.6 wt. % of a soft ferrite powder and which is primarily suited for use in rapidly switching solenoid valves in motor vehicle engines. Furthermore, a method for manufacturing such a magnetically soft powder composite material includes the following method steps: a) preparation of a starting mixture including a pure iron powder, a phosphatized iron powder, or an iron alloy powder and a soft ferrite powder, b) mixing of the starting mixture, c) compacting of the starting mixture in a press under increased pressure, d) debinding of the compacted starting mixture in an inert gas atmosphere or in an oxygen-containing gas atmosphere, and e) heat treatment of the compacted starting mixture in an oxidizing gas atmosphere at a temperature of 410° C. to 500° C.
