Process of Making Rare Earth Magnets
The rare earth magnets are made by using different process involving various stages. The popular stages of the production of rare earth magnets are:
The first stage is the manufacture of rare earth element alloys.
The metal alloy is then finely powdered.
The next step involved is pressing of powder either isostatically or pressing through die process.
The particles so pressed are oriented.
Sintering of the element is done accordingly.
The shapes are then sliced into desired shapes and sizes.
The coating is done thereafter. High Operating Temperature Block Wind Turbine NdFeB Magnet
After finishing the above tasks, the finished shapes are magnetized.
Square NdFeB magnets(block NdFeB magnets) is a very popular shape, it can be used for the magnetic separator, electrical motor, permanent magnetic generators. To make NdFeB block magnets used more widely, high temperature neodymium magnets are made from the highest quality rare earth neodymium, and rated at a 300 degree operating temperature. To ensure longevity and maximum protection from corrosion, these magnets come triple coated with a base and top finish layer of nickel, with a layer of copper in-between.
Block magnets can be called as magnet blocks, rectangle magnets, and square magnets. Neodymium block magnets are made from bigger NdFeB magnets blocks by cutting processing. Block neodymium magnets or neodymium square magnets are expressed by length, width, and height. There are three directions to magnetize for a neodymium block magnets, but they usually magnetized through height. So when you order a block neodymium magnets, please clearly tell us the magnetized direction. We have wide size range of neodymium block magnets for sale.The smallest dimension we made is 1mm and the largest dimension we made is 203.2mm(8”). The largest magnetized direction we made is 2”.
