Latest Patents

Yan Zhou holds a patent for an R-FE-B-based sintered magnet with low B content and a preparation method therefor. This invention discloses a sintered magnet comprising 28.5 wt %-31.5 wt % of R, 0.86 wt %-0.94 wt % of B, 0.2 wt %-1 wt % of Co, 0.2 wt %-0.45 wt % of Cu, 0.3 wt %-0.5 wt % of Ga, 0.02 wt %-0.2 wt % of Ti, and 61 wt %-69.5 wt % of Fe. The sintered magnet features an R-TM series phase accounting for 75% or more of the total volume of grain boundaries. This invention optimizes the content ranges of R, B, Co, Cu, Ga, and Ti, resulting in a higher volume fraction of the R-TM series phase in grain boundary phases, which leads to improved Hcj and SQ values.
