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.
Neodymium magnets (NdFeB), commonly known as ‘rare earth’ magnets are high-performance permanent magnets constructed from an alloy of neodymium, iron and boron. They are true permanent magnets and will not lose their magnetism unless they are heated to a temperature which exceeds the maximum operating temperature rating or their protective plating is damaged and water ingress causes rusting, which over time will magnetically and mechanically damage the magnets.
Rare Earth permanent magnet (NdFeB) has the strongest magnetism nowadays. It does not only has high remanence, high coercivity, high energy product, and high-functional, but also it can processed into a variety of sizes easily. Now, it is widely used in avigation, spaceflight, electron, electrical sound, electrical machinery, apparatus, meters, medical technology, and especially apply to develop high-performance, small and light replacements.

Neodymium magnets have extremely resistance to demagnetization with Hci, Intrisic coercive force, over 12,000 Oe. Because of very high (BH)max and Hci, neodymium magnets could be used as a reversible medium for large amount of energy transformation in miniaturized application where a strong magnetic demagnetization field exists , such as computer hard drive.

High performance actuator and motor design requires the use of materials that push the limits of material science. Magnet material selection is critical and we can assist in the selection of the best material. Tradeoffs in the selection include temperature, residual induction, coercivity and environment.
Industrial magnets are high-strength magnets that have certain characteristics that make them ideal for applications in the industrial industry. In general, a wide spectrum of industries are increasingly using high-strength magnets to do all kinds of work, from physical metal lifting and separating to motor activation and Magnetic Resonance Imaging (MRI). Different applications require different types of industrial magnets. Industrial magnets can be broken up into two main categories: non-permanent and permanent. Non-permanent magnets are electromagnets which require an outside electric current to be magnetized or demagnetized. Permanent magnets include ceramic magnets (also known as ferrite magnets), alnico magnets and rare earth magnets. Ceramic magnets have lower magnetic power and are more brittle and easily breakable than some other magnets, but they are cost-effective and retain magnetism under corrosion and vibration. Rare earth magnets are less cost-effective to manufacture but are far more powerful and retain their magnetism better than ferrite magnets. Neodymium magnets are the strongest and most commonly used industrial rare earth magnet; sheet magnets are made from a flexible ferrite-plastic composite which is extruded into sheets and used in automotive and consumer industries. There are many different types of magnetic materials that industrial magnets can be fabricated from. The most important properties magnet manufacturers consider during fabrication are porosity; ease of fabrication; magnetic retention (or magnetic permanence) under heat, corrosion and vibration; magnetic strength; and cost. Types of permanent magnets are made from different composites and therefore have very different properties and applications. For instance, ceramic and alnico magnets are most often used for physical lifting and separating.
