Our super strong neodymium disc magnets have wide variety grade N35, N38, N40, N42, N45, N50 and N52. The strong neodymium discs have Nicuni, Zinc and Epoxy coatings, sometimes the disk magnets with a countersunk hole that drilled in the middle to attach it to nonmetallic materials, such as wood or plastic plant. These round magnets can allow the screw’s head to reside below, or maybe with the face of the magnet to ensure it doesn’t interfere with the magnet’s performance.

This powerful neodymium block magnet measures 1/2″ in length, 1/4″ in width, and 1/32″ in thickness, with the pull force of 3.4 lb vertically. It is made from an alloy of neodymium, iron and boron, plated with triple layers of nickel-copper-nickel for effective corrosion protection.
The applications of this neodymium block magnet include automotive, consumer electronics, home appliances, industrial equipment & automation, information technology products, medical devices and so on.
We recognize the applications as the foundation of many of today’s highly technical devices. We offer the full range of permanent magnet material that is available today. We produce proven compliant magnets, on demand for our customers and can offer a wide variety of solutions in complex configurations.
JOFOV Magnetics prepares its anisotropic powders by either casting an alloy melt into a mold, or strip casting. Strip casting offers the advantage of better chemical stability. Subsequently, the ingot from the mold or the flakes from strip casting are pulverized to a uniform grain/particle size. The best method for obtaining the desired grain size is by HDDR. The HDDR [hydrogenation-decomposition-desorption-recombination] process yields a more homogenous particle size with a minimum of α-Fe, and Nd-rich phases. Anisotropic Nd-Fe-B, HDDR powders prepared from strip cast alloys are used for the HAST [Highly Accelerated Stress Test] grades of NdFeB Magnets, including N, H, SH, UH, EH, and BJA Magnetics exclusive “W” grades for Wind Power applications.

High-speed permanent magnet motors offer increased energy efficiency compared to conventional asynchronous induction motors. A permanent magnet motor has air-cooled winding heads and water-cooled housing for reliable operation, and extremely low loss lamination grade material in the motor core result in low iron losses. Non-contact magnetic bearings are used to hold the motor shaft in place, so there is less vibration and no friction between the components, resulting in less wear.
