Substitution of Ce for (Nd,Pr) in Melt-Spun (Nd,Pr)-Fe-B Powders

The effect of Ce substitution in (Nd,Pr)-Fe-B melt-spun powders has been studied. It has been found that all Ce substituted powder samples retain the R2Fe14B single phase structure. While Ce substitution leads to lower magnetic properties, lower Curie temperature and higher flux aging loss in bonded magnets, (Nd,Pr,Ce)-Fe-B melt-spun powders with up to 50% Ce substitution exhibit acceptable overall room-temperature magnetic properties and improved magnetization behavior, and offer a potential low-cost alternative product for low- to moderate-temperature applications.

MQP premium option available for selected grades

Leveraging over 20 years of jetcasting experience and continuous technological improvements to our powder making processes, we are introducing a new service providing the upper half specification (Br and BHmax) for high end MQP™ grades. MQP™ premium grades help you to achieve more consistent magnet performance within a narrower specification and produce higher performing magnets with better performing powder properties

New Enhanced Compound Technology

Magnequench introduces an enhanced compound technology which allows for more stable magnet weight with better feed stability and flow ability to improve the magnet making. With this improved technology, it is possible for magnet making to be more consistent and less expensive.

Introducing MQP-15-9HD-20178

A high density isotropic powder designed for the manufacturing of bonded magnets with superior magnetic properties. Based on a patented and cost optimized Nd-Pr-Fe-B alloy composition, it can be used as a cost effective alternative to MQP-B+-20056-070.

Latest Research

Permanent magnet synchronous motor drive using hybrid PI speed controller with inherent and noninherent switching functions.
Optimal use of higher-density bonded neodymium magnets is helpful in achieving weight and volume reduction in permanent magnet motors, resulting in raw material cost savings.
This material demonstrated good magnetic properties and saturation magnetization, at best ~50 emu/g. Mechanical properties of the compacts were good, and comparable to those of the polycrystalline Ni-Mn-Ga samples in compression.
This paper presents a manufacturing method called Combustion Driven Compaction (CDC) for the manufacture of isotropic bonded NdFeB magnets (bonded Neo). Magnets produced by the CDC method have density up to 6.5 g/cm3 which is 7-10% higher compared to commercially available bonded Neo magnets of the same shape.
