Rare Earth Super Strong powerful magnetic n42 block sintered Ndfeb neodymium magnets
Company Profile
Permanent Magnet Materials Introduction
Permanent magnets are used in the following major groups: acoustic transducers, motors and generators, magneto mechanical devices, and magnetic field and imaging systems. You will find permanent magnets in many products, such as televisions, telephones, computers, audio systems and automobiles.
The permanent magnet family consists of non-rare earth permanent magnets and rare earth magnets. The non-rare earth magnets include Alnico magnets and Ceramic magnets. Rare earth magnets include Sm-Co magnets and NdFeB magnets (Neodymium-Iron-Boron).
Although non-rare earth magnets are used in the majority of these applications due to their economic cost, rare earth permanent magnets have many distinguishing characteristics, such as a large Maximum Energy Product, Two major families of rare earth permanent magnets, Sm-Co magnets and NdFeB magnets.
How to Choose Permanent Magnet Materials
Each permanent magnet material discussed above has its own pros and cons. How to choose the right one for your particular application is a challenge to any user. A balance between cost and performance must be considered in selecting of permanent magnet material. In Reference Information section of this page, several reference books are listed. Following is a Comparison Table to help you select a right permanent magnet material for your applications.

COCOMAG PRODUCTION
Sintered Ndfeb permanent magnet is produced by powder metallurgy. From material preparation to finished product delivery, it generally goes through more than a dozen process links, including several detection and analysis in different stages.The whole production process is a system engineering, linked together. Generally, production of ndfeb is a big, complicatedand interlocking system.The process of producing the blank of the magnet is called the "pre-production", and the process of processing the blank into the final product is called the "post-processing". Magnetic material manufacturers are mainly divided into two categories,
one is the manufacturers that have both the "Pre" and "Post"processing, and the other is the processing manufacturers that focus on the "post process".
