Neodymium magnets - Import export

Neodymium magnet (aka NdFeB magnet), is the third generation of rare earth magnet, which is composed of Neodymium, Iron, Boron and a few transition metals. With high remanence, high coercive force, high energy product, and high performance /cost, Neodymium magnet is currently the strongest magnet available in the world. Manufacturing Process Neodymium, Iron, Boron and a few transition metals will be mixed into the Neodymium powder, then fine Neodymium powder will be compacted in a die and sintered, fusing the powder in a solid state. There are two ways of pressing die pressing and isostatic pressing. Sintered parts normally need some finish machining in order to meet final tolerances. Machining & Tolerance Generally, Neodymium magnet must be machined using diamondgrinding techniques. Sometimes, machining operations may be performed on Neodymium materials with carbide tools, but surface finishes thus obtained may be less than optimal.

Countersunk Magnet is a new generation of neodymium magnet, which has expanded the range of application, whether this object is wooden, plastic or steel, we can also use countersunk magnet to fix in place with screws, which allows the magnet to be easily fastened into place for a temporary or permanent fixing purpose. The countersunk magnet is available with a countersink on the north face or south face of the magnet, they can work with M4, M5, M6, M8 etc. countersunk screws. WhetherNorth pole or South pole is on the magnetic face, countersunk magnet can be as a pair to attact or repel when they are used. That is to say, when you are using two countersunk magnets together, like poles repel and opposite poles attract.

1.Description Pot magnets with eyebolt, one of magnetic assemblies, is also called pot magnet. This product is made of small metal cup and disc neodymium magnet with nickel coating, as the corrosion resistance of NdFeB magnet is considered poor. These Neodymium magnets are sunken in to a steel shell meaning that the north pole is on the center of the magnetic face and the south pole is on the outer edge around it. The steel pot increases the adhesive force of the magnets giving them an incredible hold for their size. An added advantage of these magnets is that they are resistant to chipping or cracking following constant impact with a steel surface. However, they are not suitable for underwater applications. 2.Application Pot magnets with eyebolt are very versatile product for hanging most things, we can attach them to metal surface without marking, meanwhile we can easily remove the eyebolt, generally we can attract coins, other steel plates

The corrosion resistance of Neodymium magnet is considered poor, surface coating is highly recommended for Neodymium magnets. With the expansion of elevators, wind turbines and permanent motors application, the users need higher requirement on corrosion resistance of Neodymium magnet, as the glue cohesiveness of unplated magnet is much better than plated magnets, also unplated products are better in the security. Now, more and more customers tend to use unplated magnets, upon this condition we have developed ultralow weight loss magnets after the continuous innovation and study. Normally, the weight loss test is over 150mg/cm² in the industry of Neodymium magnet, this will be different for magnets produced from different material formulation and manufacturing process. A lot of our new magnets can reach to 1mg/cm², (Testing condition HAST standard for 168hrs), due to its very low weight loss, the corrosion resistance is excellent
