Corrosion-resistant high-performance rare earth permanent magnet material

The invention relates to a corrosion-resistant high-performance rare earth permanent magnet material. The corrosion-resistant high-performance rare earth permanent magnet material is prepared from, by weight, 20-35% of rare earth elements, 0.8-1.5% of boron, 0.02-0.2% of tungsten, 0.5-5% of silicon, 0.1-3% of vanadium, 0.02-0.5% of gallium, 0.02-0.5% of zirconium, 0.02-0.5% of chromium, 0.5-5% of copper and the balance iron and inevitable impurities. The rare earth permanent magnet material has high corrosion resistance and excellent mechanical performance and is low in cost and high in stability, a preparation method is simple, and large-scale industrial production can be easily achieved.
