NEOQUENCH-DR ND-31HR is part of a family of Nd-Fe-B-based radially oriented anisotropic magnets manufactured by rapid quenching of material into flakes, which are then hot pressed to full density and hot formed into the final products by an advanced extrusion technique. This datasheet provides information on composition, physical properties, hardness, elasticity, and bend strength. It also includes information on corrosion resistance as well as forming and heat treating. Filing Code: ND-1. Producer or source: Daido Steel Company Ltd.
