Neodymium Magnets Manufacturing Methods

Neodymium Magnets Manufacturing Methods

Sintered Neodymium Iron Boron Magnets: The sintered Neodymium Iron Boron magnet is produced by the OPS (orient-press-sinter) method. A crystalline alloy of Neodymium, Iron, and Boron is ground to a sub-micron powder using a ball mill, then aligned in a strong magnetic field, and pressed into a basic shape. The resultant “block” is then sintered, thereby fusing the material into a solid metal.

Bonded Neodymium Magnets: The bonded Neodymium Iron Boron materials are typically anisotropic. They can be made isotropic, and are manufactured using “binders,” such as epoxy resins or nylon to hold the powder in place, rather than “sintering” the alloy. Energy products of the bonded magnet range from 5 MGOe to 10 MGOe. Two basic processes are used: Compression Molding Binders are epoxy resins, and energy products of 10 MGOe are achievable. Moderately complex shapes can be achieved. Injection Molding Binders are generally nylon, but epoxy resins may also be used. Energy products are lower than compression molding; however, more complex shapes can be achieved without final processing, which makes it cost effective for low to medium performance applications which are cost sensitive. The bonded Neodymium Iron Boron magnet may be used without surface treatment; however, coating is recommended. Generally, spray coatings are used, such has phenolic or epoxy coating.
