Neodymium iron boron - the most powerful "rare earth" permanent magnets known as the most powerful "rare earth", the term is more modern, and in 1984 for the first time to become commercially available. The neodymium iron boron magnets have the highest B bromide, iodine and any of the BHmax formulations of the, and also have a very high HC (defined by Xia Wen). However, they are very crisp, very difficult to process, sensitive to corrosion and high temperature. There are used at home, workshop, pickup, laboratory, wind turbine, spacecraft, etc.. We are new and surplus inventory. In many sizes and almost all magnet application of neodymium iron boron is because of its incredible intensity and coercive force, at a reasonable price, the best choice! In the application of power generation, it can be predicted that the output power of the ceramic magnets is 4-5 times as much as that of the neodymium iron boron magnet.
If you use a magnet in the outdoors?
Neodymium iron boron magnets are susceptible to corrosion. The name of the 'iron' iron, and it is rusty! Many of our magnets, nickel, zinc, gold or epoxy paint, protect them from moisture. If the coating is damaged (in the case of the surplus magnets), the magnets will rust if exposed to water or moisture. If this is your concern, you can easily add another layer of protection, impregnated with epoxy or plastic coated magnets.
I have already known about the patent issue of the neodymium iron boron magnet, and if you apply for a permit for a magnet?
Neodymium iron boron magnets are a relatively new invention - the first time they became commercially available in 1984. GM holds the patent, some hard drive manufacturing business than non prosecution card of NdFeB magnets. From then on, the patent has been sold to Sumitomo commercial, who is easy to license for magnet manufacturers around the world. All neodymium iron boron magnets are currently under international patent protection. All of our magnets, whether new, legal, licensed, or earnings from different industries.
How magnets are made? Can I have them at home?
Manufacturing: neodymium iron boron magnets are complex manufacturing. Powder of neodymium iron boron material packaging, mold, and then sintering. Non magnetized "magnets", and then form the correct size and plating. Magnetization, which is placed in a very expensive machine, generates an instantaneous magnetic field with extremely high power supply, using high voltage capacitive discharge and coil. The polarity of the finished magnet depends on how it is oriented to the magnetization machine, and how it is oriented in the sintering mixed particles. This makes it impossible for domestic manufacturing. However, so you can make a simple steel magnet at home. To take a nail and stroke with a powerful neodymium iron boron magnet 20 or 30 times, it is always on the nail to move only one direction of the magnet. Presto, nails will be magnetized, the city accounted for very weak.
Can I cut, drill or machine its size and shape of the magnets?
Yes, you can. Aluminum nickel cobalt magnets are very easy in any way you wish. Neodymium iron boron magnets are very hard and brittle properties. Although they can be cut, drilled and processed, it should only be able to do ceramic experience of people. If the magnets get about 300 degrees Fahrenheit, they will lose their magnetism permanently. They are flammable, it is not difficult to grinding or machining, let them (or cutting chips and dust was hot to the touch, they lit. If they do not light, the smoke is toxic, such as magnesium, material burning speed is very fast, hot! In our experience, it should be done to do any machining of these magnets with diamond tools, according to a large number of cooling fluid with good ventilation and the risk of fire in the mind.
