The small round magnets Ø10x5mm are made of the strongest rare earth magnetic material, and with 4mm through the hole. All grades from N35 to N52 are suitable for strong rare earth neodymium ring magnets Ø10xØ4x5mm, the grade of N42 produces about 2.5kg pull force. 10x4x5mm neodymium ring magnets are supplied with nickel plated unless specified. As a professional neodymium ring magnets factory in China, BeiLun Meank can supply retail packaging for the small ring magnets. Discount is provided for large orders.
