A homocentric-squares-shaped imbedding composite hammer made of abrasion-resisting materials is composed of a hammer handle, a hammer end and a homocentric-squares-shaped imbedding body. The hammer handle and the hammer end are combined. The homocentric-squares-shaped imbedding body is a casting which comprises a left face, a right face, an upper face and a lower face and is made of abrasion-resisting materials. The homocentric-squares-shaped imbedding body wraps the periphery of the crushing face of the hammer end, and an abrasion-resisting crushing face of the hammer end is jointly composed. The abrasion-resisting capability of the homocentric-squares-shaped imbedding body is higher than that of the hammer end. Materials relatively prone to being abraded are located in the middle of the crushing face and are not prone to being abraded, a material layer relatively not prone to being abraded is located on the edge of the crushing face and can be abraded more slowly, accordingly, the even abrasion loss can be formed on the center and the edge of the crushing face of the hammer, and the shape of the plane of the whole crushing face is always kept.
