摘要：
An alloy for bonded magnet alloy of the present invention includes at least Fe as a main component, 11-15 at % rare-earth element (R) that includes yttrium (Y) and does not include lanthanum (La), 5.5-10.8 at % B and 0.01-1.0 at % La, and has superior corrosion resistance. Using the obtained magnet powder by applying the d-HDDR process etc. to this bonded magnet, bonded magnet with not only magnetic properties but also reliability such as corrosion resistance and heat resistance etc., can be achieved.
