Rare Earth Magnets are the strongest permanent magnets for sale today. Small rare earth magnets are perfect for crafts and DIY. We also sell large rare earth magnets for heavy duty projects where super strong pull force is required.
NEODYMIUM MAGNETS ARE NOT SAFE FOR CHILDREN.

High Corrosion Resistant Magnets
Under the Environment of high temperature, high pressure and high humidity, the weight loss level of uncoated magnets can qualitatively reflect its serving life clearly. Referring to the standard IEC68-2-66 and after 20 days, Hast testing, weight loss of less than 2mg/cm² is available for Repumag, which is the top level worldwide.

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.
After finishing the above tasks, the finished shapes are magnetized. 45 MGOe (N45) Quadrapolar Rare Earth Neodymium Magnets
