Every production batch of neodymium magnetic balls is carefully checked from raw material to final packaging. The neodymium powder is mixed with iron and boron, pressed under high pressure, and sintered at precise temperatures to achieve a dense magnetic structure. After sintering, each magnet is machined and polished until the surface reaches a perfect spherical finish. The uniform geometry guarantees stable magnetic performance and consistent pull strength across every piece.

Once the magnets are shaped, they are coated according to the customer’s request. Nickel plating provides a bright metallic look and strong corrosion protection. Epoxy or rubber coatings create a soft, non-slip finish ideal for handling or decorative use. Colored coatings are produced with non-toxic pigments that maintain their shade and gloss even after long exposure to light or moisture. Each magnet passes a coating adhesion test to ensure the finish will not peel or chip during normal use.

Temperature stability is another important feature. Standard neodymium magnetic balls can operate safely up to around 80°C. For specialized applications, high-temperature grades can withstand 120°C or more without significant loss of magnetic strength.
