Magnetic bodies prodn. - by injecting or casting a mixt. of magnetic powder and nonmagnetic liq. alloy in a mould aligned in a magnetic field

摘要

A process for making a magnet from a powder of a alloy of Co and rare earths by mixing a liquid alloy of non-magnetic materials with the magnetic alloy and injecting/casting the mixt. in(to) a mould suitably aligned in a magnetic field. Prodn. time is reduced and O2 ingress is avoided.
