Abstract: The present invention relates to an anti-galling alloy with finely dispersed precipitates, more particularly to an anti-galling alloy comprising Ni, Cr, Sn, Bi, Mo, Fe, Si and Te, in which the matrix has a fine dendritic structure and the Bi-rich precipitates are finely dispersed between the dendritic structure, so that the anti-galling properties are significantly improved, while physicochemical properties such as corrosion resistance and hardness are not deteriorated. The anti-galling alloy of the present invention will greatly contribute to the improvement in life cycle and mechanical precision of a variety of wet machinery parts such as rotor, shaft, valve and mechanical sealing.
