Cooling from the sintering temperature was either achieved quickly, by placing a water-cooling jacket around the furnace vessel, or slowly, by leaving the vessel to cool in the furnace. Magnetic characterisation of the HD magnets was carried out using a permeameter, after full saturation in a field of 4.5 T. Results and discussion
If oxygen is present, the resultant oxides destroy the magnetic performance of the NdFeB. The sintering process also causes shrinkage of the magnet as the powder fuses together. The shrinkage gives a magnet close to the required shape but the shrinkage is usually uneven (e.g. a ring may shrink to become an oval).
If you are interested in China Sintering Furnace, You will be amazed by the variety of the product choices such as vacuum furnace, furnace, heat treatment furnace. Besides, their competitive & cheap price of Sintering Furnace factory would get you an edge in your own market.
How Neodymium Magnets are Made How Sintered Neodymium Magnets are Made. We describe the steps involved in manufacturing neodymium magnets, with some notes on what this means for practical magnet users. 1. Prepare Materials for the Reaction. The basic compound for most Neodymium magnets is Nd 2 Fe 14 B. In practice, the actual chemical reaction

These principles today much more than ever form the basis of our success as an internationally active mid-size business for NdFeB Production Line, Vacuum Induction Melting Furnace, Induction Heating Machine, Powder Test Equipment, Excellent quality, competitive price, punctual delivery and
the liquid phase sintering process) that helps the magnetic decoupling of the grains. Despite their magnetic and cost advantages, the NdFeB magnets have suffered because of their poor intrinsic cor-rosion resistance, since under humidity and temperature the Nd-rich intergranular phase transforms into Nd(OH) 3. One
Proceedings of 19th International Workshop on Rare Earth Permanent Magnets & Their Applications Development of NdFeB Magnet Industry in New Century LUO Yang (IEEE TC-15 Voting Member, Beijing, China) Abstract: This year is 23rd anniversary of NdFeB magnet since its coming in 1983.
Disclosed are a production method and production device for producing a thin-shaped NdFeB sintered magnet with superior magnetic properties, particularly coercive force and degree of orientation, and an NdFeB sintered magnet produced with said production method and production device.
Bonded NdFeB magnets are manufactured by binding rapid-quenching NdFeB powder. The powder is mixed with resin to form a magnet by compression molding with epoxy or infection molding with nylon. The latter technique is particular effective in large volume production, though the magnetic value of products is lower than lower than those made with
According to the principle of electromagnetic induction, the current can produce a magnetic field, the use of strong magnetic field will be hard magnetic material is generally referred to as the magnetic material of the magnet, in fact, several different things: the most common magnets, such as general speaker magnet, Magnetic oxygen magnet.
