PROBLEM TO BE SOLVED: To stabilize brake performance by forming a metal compound material as a raw material formed in such a constitution that a gray cast iron in which flake graphite is deposited on a ferrite base is formed as a base material and hard ceramic particle having good heat resistance and abrasion resistance is dispersed on the ferrite base. SOLUTION: A metal compound material formed in such a constitution that a gray cast iron in which flake graphite is deposited on a ferrite base is formed as a base material and hard ceramic particle having good heat resistance and abrasion resistance is dispersed on the ferrite base, is used in a raw material of a rotor for a brake used for an automobile and the like. A content of ceramic particle dispersed in the ferrite base is not limited especially, but the content is set to 2.0 to 30 wt.%, and the content is preferably set to 5.0 to 10 wt.%. For example, the diameter of the ceramic particle is set to be within 5 to 500μm. The ferrite base is used in such that way, and thereby, a desired anticorrosion is provided. As a result, reduction of abrasion resistance is obtained by dispersing ceramic particle on the ferrite base.
