Tech Overview.

NdFeB permanent magnets are hard and extremely brittle. To produce the final magnet shape they have to be machined and this is a me consuming, energy intensive process that produces a significant amount of material waste.

University of Birmingham researchers have developed a net-shape manufacturing technique for NdFeB magnets based on a novel hydrogen ductilisation process (HyDP) to provide a ductile structure allowing mechanical shaping without fracturing the material.
