Sintered magnets receive some degree of machining which can range from grinding them smooth and parallel, OD or ID grinding, or slicing block magnets into smaller parts. The magnet material is both brittle and very hard (Rockwell C 57 to 61) and requires diamond wheels for slicing and diamond or special abrasive wheels for grinding.

Some sintered Sm-Co devices are inefficient and could perform as well at a lower cost by substituting a pressed-to-size bonded Nd-Fe-B part. Explore online our FAQ page and get answers related to Bonded Magnet Materials. For any other information, call us …

For all the Magfine bonded magnets, the remanence ratio M r /M s is about 0.89 and comparable to that of the MQA bonded magnets (0.88). The magnetic alignment of the particles is very similar for both types of anisotropic Nd–Fe–B powder under processing conditions and achieves a particle DOA Φ p = 0.97.

Sintered magnets have a preferred magnetization direction. Bonded magnets generate a lower peak magnetic field strength - about 90% of sintered. But bonded magnets are more durable and easier to assemble. Chris found the sintered magnets in the Flow V2 performed better, with 10% higher field strength. Swapping the rotor did show a …

The (BH) max of the bonded magnets with the size of ≤38 μm is 11.4 MGOe, which is a little higher than that of the magnets with the size of 38-45 μm. The slight increase of the (BH) max can be attributed to the relatively wide distribution of the particles, making the bonded magnets a little denser (6.59 g/cm 3 vs. 6.49 g/cm 3).

Preparation process of bonded Nd-Fe-B magnets. First, 96.9 wt% Nd-Fe-B powders, 3 wt% W-EP/SS binder and 0.1 wt% dicyandiamide were mixed and stirred to obtain a uniform mixture and the magnetic particles become dry. Second, the mixture was poured into a mold to get a compact bulk by exerting pressure.

The goal of this research is to fabricate near-net-shape isotropic (Nd)2Fe14B-based (NdFeB) bonded magnets using a three dimensional process to compete with conventional injection molding techniques used for bonded magnets. Additive manufacturing minimizes the waste of critical materials and allows for the creation of …

Magnet Manufacturing. Bunting Magnetics Europe has been manufacturing BREMAG compression bonded magnets since the late 1980's. In 1992, a second manufacturing facility was set up in the USA, which now offers both compression and injection moulded NdFeB magnets, including BREMAG. In this time we have gained a huge amount of …
