SmCo5 base permanent magnet ribbon magnet and preparation method thereof

The invention provides a SmCo5 base permanent magnet ribbon magnet and a preparation method thereof, and relates to magnets of hard magnetic material containing rare earth metals and magnetic transition metals. Through the addition of varying amounts of Fe-Cr-Co alloys in the SmCo5 series alloy composition, which is equivalent to regularly adding in a multi-component mode to the Fe-Cr-Co alloy composition elements in the SmCo5 series alloy, the SmCo5 base permanent magnet ribbon magnet with an elementary composition general formula of SmxCoyCuzFeuCrvSiwTieMof is prepared. The shortcomings are overcome for such cases when in the existing technology after single elements are added, while improvements are made for one or limited several performances of the magnet materials, other performances are often reduced or changed, so that the performance has large differences from the theoretical value, when a variety of elements are added, no rules can be followed, and inconveniences are brought to the subsequent resear
