In this paper, ingot of Sm2Co17 type permanent magnet materials from two kinds of cooling molds was comprehensively sampled, and studied by metallographic observation and component analysis. The results indicates that Fe-Co, Sm-Cu and Zr rich phase are formed in the ingot, and the position and distribution of the precipitated phases were also determined. These consequences provide important reference for the research of Sm2Co17 type permanent magnet material.
