Rare Earth Magnets
If you are looking for where to buy rare earth magnets, Argus Magnetics supplies Neodymium magnets and Samarium Cobalt magnets which are among the strongest rare earth magnets available. They can be made in many different sizes and shapes such as blocks, discs and rings. As with all of the products Argus offers, we can custom make any shape or size to your exact specifications.
Neodymium Magnets are very strong, but very sensitive to temperature and corrosion. To combat temperature we can help you to select the grade that is appropriate for the operating temperature that you may require. To combat corrosion, neodymium magnets are coated on the outside. Most commonly they will be coated with nickel-copper-nickel, but can also be coated with epoxy, gold and parylene.
Samarium Cobalt Magnets provide a great value because not only are they very strong, but they resist both corrosion and temperature very well. Samarium magnets do not require any coating. For a magnet that seems to have it all, the only drawback is that they are the most expensive to produce.
We offer a wide variety of rare earth magnets in SmCo Disc, NdFeB Block, NdFeB Disc, SmCo Block, and NdFeB Ring and they come in an assortment of sizes and grades.
