In the present work, hard magnetic behaviours of (Sm<sub>1-y</sub>Pr<sub>y</sub>)<sub>2</sub>Fe<sub>17</sub>N<sub>x</sub> magnets are investigated. Remanence enhancement is observed when some of the Sm atoms are replaced by Pr atoms in the compounds, which is due to the larger saturation magnetization of (Sm<sub>1-y</sub>Pr<sub>y</sub>)<sub>2</sub>Fe<sub>17</sub>N<sub>x</sub> than of pure Sm<sub>2</sub>Fe<sub>17</sub>N<sub>x</sub>. Meanwhile the coercivity of (Sm<sub>1-y</sub>Pr<sub>y</sub>)<sub>2</sub>Fe<sub>17</sub>N<sub>x</sub> decreases with increasing Pr content in the compounds, which corresponds to the decrease of the anisotropy field in the compounds. In order to obtain a combined good effect on the remanence and the coercivity, the Pr content y should be no more than 0.4 in (Sm<sub>1-y</sub>Pr<sub>y</sub>)<sub>2</sub>Fe<sub>17</sub>N<sub>x</sub> nitrides.
