This neodymium round base magnet is made of a super strong neodymium magnet encased inside of a chrome plated steel cup and countersunk for a #6 screw. The neodymium magnet is bonded inside of the cup with adhesives. This design forms a magnetic circuit which triples the holding force to 16 lbs! At the same time, the steel cup also protects the magnet from being damaged when frequently used. The counter sunk hole on the magnet is provided for easy mounting.

1.Introduction: rare earth neodymium countersunk magnet is well known as neodymium magnet is known as the third generation of rare earth permanent magnet.
2.Material Content of Chemical element : made from 32% of Nd, 64% of Fe, 1% of B (Nd 12 Fe 14 B) as well as few of other elements like Dy, Tb, Co, Nb, Ga, Al, Cu, etc.
3.Grade: Standard N35 rare earth neodymium countersunk magnet according to China National Inindustrial Standard for neodymium magnets manufacturer.
4.Magnetic force: Usually 400-600 times of itself weight within its max temperature, the magnetic force can last forever.
5. Coating or plating: Nickel-Cu-Nickel which is environment friendly and can get approval by third part inspection like SGS. Other coating ways are also available like Zinc, Gold, Silver, Epoxy, Parylene, etc. Please kindly refer to Tips of coating or visit our company website directly. You may choose coating or not before shipment.
6. Magnetization: usually thickness direction magnetization, if you have special purpose and need other magnetization ways, you may remind us when send inquiry to us. Please kindly refer to Tips of magnetization or visit our company website to see more magnetization ways. You may choose to magnetize or non-magnetize before shipment.
