N52 Super Strong Rectangular Neodymium Magnets

Permanent block magnet made from N35H grade(other grades are available) sintered Neodymium Iron Boron (NdFeB). This type of magnet material gives the highest energy per unit volume of any Permanent Magnet material, being capable of lifting up to 1000 times its own weight. Suitable applications for this block magnet include audio, aerospace, automotive, medical and renewable energy.

Sintered Neodymium Magnets (NdFeB), are high-performance permanent magnets constructed from an alloy of neodymium, iron and boron. They are a member of the rare earth magnet family, and are well known for being the strongest magnets in the world，they are much stronger than Permanent Ferrite Magnets.

NdFeB magnets have a high resistance to demagnetization and are plated (typically with nickel) to protect them from corrosion and chipping. They are the most compact magnets commercially available,especially suitable for the development of magnets for high-performance, compact and light products.

Neodymium magnets are easily formed into various sizes such as blocks, discs, rings, arcs, spheres, triangles, trapezoids,and widely used in many fields such as magnets for aviation, electronics, auto industry,instruments, meters, machine and medical instruments.

Will Neodymium Magnet lose the strength with time?
No, neodymium magnet will last a lifetime.

How do I separate large magnets that are stuck together?
The best methods for separating magnets involve sliding one magnet across the other. A good technique is to place one magnet on the edge of a strong table or countertop and push down on the other magnet which should extend beyond the countertop. Make sure there are no ferrous parts below the countertop to interfere with the free magnet once it breaks loose.
