Rare earth magnetic material consists of the elements scandium and yttrium, as well as elements in the lanthanide series and are much stronger than magnets composed of iron of alnico. Despite the name, rare earth elements are no longer particularly rare or difficult to mine and it is now possible to buy rare earth magnets at a relatively low price.
Large rare earth magnets typically produce magnetic field strengths in excess of 1.2 teslas while conventional iron magnets rarely exceed 0.1 teslas. However, industrial rare earth magnets must normally be coated with nickel because they are extremely brittle.
The most common type of industrial rare earth magnets are made from neodymium, iron and boron. Companies with neodymium magnets for sale recommend that these magnets not be used at temperatures above 300 degrees F. Samarium-cobalt magnets are weaker and more expensive but have better resistance to oxidation and temperature.
It is now common to find rare earth magnets in audio speakers and computer hard drives.
Three points to consider when buying or selling rare earth magnets are:
- Manufacturers need resellers to shop their wares;
- Manufacturers will deal directly with sellers;
- The Internet solves a previous advertising dilemma.
Action Steps
The best contacts and resources to help you get it done
Become a reseller for a rare earth magnet supplier
Rare earth magnet manufacturers frequently need help in selling their products. A retailer who already has an online presence and sells complementary products may wish to buy rare earth magnets for resale.
I recommend: National Imports actively recruits resellers for their line of rare earth magnets. You can find an application form
here.
Order industrial rare earth magnets directly from manufacturers
Manufacturers offer the best prices on large orders and are able to provide the greatest variety of sizes. Manufacturers of rare earth magnets are also more likely to make magnets in custom shapes.
I recommend: Find several shapes and sizes in stock at
Armstrong Magnetics, Inc. Armstrong offers discounts for online orders and additional discounts for large orders.
Magnet Sales & Manufacturing offers a large collection of the tools you will need to calculate the required strengths of your magnets.
Get your company listed in directories on the Internet
Manufacturers with rare earth magnets for sale can have difficulty finding an advertising venue for their products and use trade associations and listings on the internet.
I recommend: Apply to be listed with the
Rare-Earth Magnetics Association. This is a public information site that should be familiar to anyone with rare earth magnets for sale. You can also apply to
become a member of the Rare-Earth Magnetics Association.
Tips & Tactics
Helpful advice for making the most of this Guide
- If you have neodymium magnets for sale, you should know that magnets are considered a hazardous material and require special handling when shipping by air. Magnets may not be transported by air if their field strength is more than 0.00525 gauss at 15 feet.
