Round rare earth sintering permanent magnet



Product Description

Round permanent magnet is rare earth sintering magnet, also could be called as neodymium-iron-boron magnet or ndfeb magnet. There are so many grade, like n35, n45, n40, n38, n48. Our magnet for sale is competitive with high quality and performance.



Relying on advanced facilities and technical skills, scientific and canonical quality management, Flygain is not merely well known for magnets with top magnetic performance, but also applies most of our energy to develop excellent technology of surface protection, in the basic of which Flygain has created unique features with Six Advantages (6A),i.e. low weightlessness, high max continuous working temperature, high consistency, excellent adhesive force, high corrosion resistance and excellent wattability, which have met high-end market requirements completely.

A1 Low weightlessness

Under the environment of high temperature, high pressure and high humidity, the weight loss level of uncoated magnets can qualitatively reflect its serving life clearly. Referring to the standard IEC68-2-66 and after 20 days HAST testing, weight loss of less than 2 mg/cm2 is available for Flygain magnets, which is the top level worldwide.

A2 High consistency

The uniformity of one batch and the continuous stability of different deliveries is the critical bolstering for customer’s high quality and mass production. Flygain magnets do well in the consistency, for example, the Cpk of (BH)max could be higher than 1.67.

A3 High working temperature

Flygain has poured much energy into enhancing the magnet working temperature through advanced technical skills and special production processes, which carried out better thermo stability and less demagnetization in the same named grade comparing with other company’s. Meanwhile, Flygain’s AH and ZH series whose working temperature running up to 230°C and 250°C separately.

A4 Excellent adhesive force on substrates

Letting round permanent magnet substrate stick to the coating (plating) is the achieved target of Flygain for coated magnet. The adhesive force can reach 15Mpa between the substance and the coating (Plating). No matter the cross cut test or the shock test Flygain magnets work well.

As the left figure, the above is Flygain Nickel coating and the below is traditional Nickel coating, the traditional coating layers could be observed partial peeling off cross cut test

A5 Excellent corrosion resistance

Flygain’s nickel permanent magnet can stand more than 500hrs SST, which is one of the reliable winning cards for customers. Moreover, pioneering in IVD Aluminum technology, Flygain become the first supplier, up to now the sole in china, who is able to offer the superexcellent choice for top-class customers.

The figure from left: Flygain Nickel coating, Flygain IVD-AI coating, traditional Nickel coating, each of which is after 500 hrs SST test.

A6 Excellent wettability for glue

“Let glue fall in love with magnet only”. That could release customers from the annoyance that magnet falling off. The shear strength can reach 35Mpa, around 50% stronger than traditional Nickel Coating.



Magnetic property

Rare earth sintering magnet first appeared in the 1980s'.Wildly used in motors, speaker, toys and electronic products. NdFe14B is the main element in Neodymium and gives NdFeB magnet strong magnetic power. In fact, maximum BH is more than ten times that of Ferrite. Neodymium has good machinability properties and can work well at temperatures up to 200°C. Since neodymium power magnet easily rusts, plating with such metals as Zn, Ni, Au, Epoxy is necessary.
