The solidification experiment of Cu-25%Ag alloy used in high field magnet was carried out under high magnetic field, the precipitation of Ag in Cu-rich dendrites, the hardness and the electrical conductivity were investigated. It was found that the Ag phase precipitated exhibites continuous rod-like morphology in the larger Cu-rich dendrites, and exhibites discontinuous particle-like morphology in the smaller Cu-rich dendrites; the number of the Ag particles is more and the size is thinner in the sample solidified under 0 T than under 12 T high magnetic field. The hardness and electrical conductivity of the alloy have changed due to the size variance of Ag precipitates.
