Ndfeb arc bonded magnet Bonded magnet materials can be made from Ceramic, NdFeB, or SmCo powders which are combined with a variety of plastic binders (Matrix). They can be either Injection Molded or Compression Bonded into complex magnet shapes with finished dimensions. Bonded magnet materials have a moderate resistance to corrosion and a low tolerance to heat because of the binder material. Bonded magnet materials are commonly used in automotive parts because they lend themselves to large production quantities and complex shape can be produced at a low cost. In contrast to sintered magnets, for plastic bonded pressed magnets are already considerably more delicate shapes producable. So, for example thin-walled rings with 27 x 24 x 30 mm and diameter tolerances of only approx. 0, 05 mm can be produced. Normally afterwards no mechanical machining is needed. In
