Profile: Rolfe Industries (Vacuumschmelze GmbH) manufactures magnetic materials and related products. VACOMAX® is our permanent magnet material of rare-earths and cobalt. These magnets feature high coercivities with simultaneously high saturation and temperature & corrosion stability. Magnets made of VACODYM® and VACOMAX® are produced powder metallurgically by sintering. Depending on size, shape, tolerances, batch size and magnetic requirements, the parts are either cut from isostatically pressed blocks or are die-pressed. When die-pressing, the powder particles are aligned by strong magnetic fields parallel (axial field for AP-grades) or perpendicular (transverse fields for TP-grades) to the direction of pressing depending on the geometry of the part. Isostatically or transverse-field pressed parts have an about 6 percent higher remanence compared to axial-field pressed magnets. Cores & inductive components are used in chokes, XDSL, transformers, current transformers and current sensors.
