Neodymium magnets are manufactured on the basis of Nd-Fe-B alloys and sintered Neodymium magnets have the highest (BH)max value among all of commercially available permanent magnets. Neodymium ring magnets are circular in shape with a concentric hole inside it. Magnet ring can be divided to pure ring or countersunk ring based on the detailed shape of the inner hole. Neodymium ring magnet should be measured by outer diameter (O.D.), inner diameter (I.D.), and thickness (T). Similar to Neodymium disc magnet, ring shaped magnet can be magnetized with its N pole and S pole opposite flat end surfaces or diametrically magnetized so as to the N pole is on one curved side and the S pole is on opposite curved side. Besides the conventional axially magnetized or diametrically magnetized magnets, radially oriented ring magnet is also available in SDM. In addition, Neodymium magnets are easily corrode under humid condition and are necessary to cover with a protective coating.

Magnetization Direction

• Magnetization Direction for all Neodymium Magnet

Inspection Capabilities

• Demagnetization Curves & Outgoing Inspection Report for Each Neodymium Rare Earth Magnet

The importance of manufacturing process's quality management and final product's quality inspection is self-evident. Quality management of manufacturing process can help manufacturer to reduce scrap rate, thus enhance qualified rate and efficiency. Quality inspection of final products will ensure customers have stable and reliable products. Quality inspection of final products is mainly including dimension, appearance, magnetic performance, and coating performance. Besides relevant professional testing equipment, automatic inspection has become a trend due to its high reliability and cost advantages.

Certifications

SDM Magnetics obtained IATF 16949:2016 and ISO9001:2015 quality management system certificates from international certification institutions. SDM Magnetics regularly arranges RoHS and REACH testing in external third-party laboratory, and all testing results are satisfying relevant directives.

Manufacturing Process

Sintered Neodymium magnet is prepared by the raw materials being melted under vacuum or inert gas atmosphere in an induction melting furnace and processed in the strip caster and thus cooled to form alloy strip. The strips are crushed and pulverized to form a fine powder ranging from 3 to 7 microns in particle size. The powder is subsequently compacted in an aligning field and sintered into dense bodies. The blanks are then machined to the specific shapes, surface treated and magnetized.
