Abstract

The invention relates to an alloy material, in particular to a fusion assisting alloy material for an adhering permanent magnet, solving a problem that a radiation magnetic ring prepared by conventional adhesive is poor in mechanical strength. The fusion assisting alloy material for the adhering permanent magnet comprises 60 to 100% of A and 0 to 40% of B by weight, wherein A is one or mixture of some of Pr, Nd, Gd, Tb, Dy and Ho based on any ratio; and the B is one or the mixture of some of Al, Ga, Cu, Mg and Sn based on any ratio. The fusion assisting alloy material for the adhering permanent magnet is reasonable in design; the mechanical strength of the radiation magnetic ring of rare-earth-iron-boron serial permanent magnet manufactured by the fusion assisting alloy material is greatly improved, and a requirement of actual industry can be completely met.

Description

technical field [0001] The invention relates to alloy materials, in particular to a flux alloy material used for bonding permanent magnets. Background technique [0002] At present, in the preparation process of the radiation magnetic ring of the rare earth-iron-boron permanent magnet, such as figure 2 As shown, the usual method is: arranging a plurality of regular-shaped magnets M into a complete ring shape, and at the same time attaching an adhesive N between adjacent magnets M, and then air-drying and condensing or baking and thermosetting to produce Multi-pole radiating magnetic ring. However, the disadvantage of the radiation magnetic ring made by the above method is: due to the limitation of the binder, the mechanical strength of the radiation magnetic ring prepared by the binder is far from enough, and the radiation magnetic ring often breaks during actual use, so it cannot Meet the requirements of the actual industry. [0003] Therefore, it is necessary to invent ...
