description	The invention relates to a high-performance rare earth permanent magnet material which comprises, by weight, 20-35% of rare earth elements, 0.8-1.5% of boron, 0.02-0.2% of magnesium, 0.5-5% of manganese, 0.1-3% of titanium, 0.02-0.5% of nickel, 0.02-0.5% of cadmium, 0.5-5% of aluminum, inevitable impurities and the balance ferrum. The mechanical performance and coercive force of the rare earth permanent magnet material are greatly improved, the cost is low, the manufacturing stability is high, the manufacturing method is simple, and large-scale industrial production is easy to achieve.
