The　Sm(CobalFe0.28Cu0.07Zr0.03)(7.6)　magnets　were　made　by　a　casting　process　with　two　different　cooling　rates.　X-ray　diffraction　analysis　shows　that　the　main　phase　of　the　two　as-cast　alloys　consist　of　1:5,　1:7,　and　2:17　(hexagonal)　phase.　While　a　few　of　rhombohedral　2:17　phases　appear　in　the　ingots　with　the　lower　cooling　rate.　The　electron　probe　micro-analysis　and　corresponding　wavelength　dispersive　x-ray　results　indicate　that　a　higher　cooling　rate　of　the　as-cast　alloy　is　helpful　to　the　uniformity　of　Cu　element　distribution　in　the　ingots　and　magnets,　especially　for　suppressing　the　formation　of　2:17　R　phase　in　ingots.　The　coercivity　and　squareness　of　magnet　prepared　from　ingot　with　higher　cooling　rate　increase　by　72　and　48　percentage,　respectively.　The　microstructure　observation　shows　that　some　cell　boundaries　are　destroyed　in　the　magnet　made　by　lower　cooling　rate,　while　the　cell　boundaries　are　well　developed　in　the　magnet　made　by　higher　cooling　rate.
