Pllease note: these magnets were 9/16" BEFORE the coating was applied. The finished product is .6mm thicker.

Why are these 9/16" Rubber Coated neodymium magnets so expensive?

One of the biggest drawbacks to Neodymium magnets is though very strong, they are very fragile. Tough coatings, such as nickel, go a long way toward protecting the magnets from cracks and breakage. However, after repeated impacts with each other or other surfaces, even the best metal coatings will fail.

One possible solution to the breakage problem is presented here. Each of these 9/16" magnets is coated in standard nickel. Then, a special 85% rubber / 15% plastic layer is applied. This impact resistant coating is more supple than regular plastic, and not prone to flaking, as with epoxy, and offers a long lasting solution to high stress environments. This is a very recent coating development and still quite expensive to produce, hence the higher than standard price. But it's worth it!!

If you plan to play with neodymium magnets A LOT - these are the magnets for you!
