Mini magnets are permanent magnets with tiny sizes widely applied in clocks, watches, chips, sensors, micro-motor, mobile phone vibration motor, digital camera, etc. Mini magnets supplied by magnet manufacturer China Rare Earth Magnet Limited are abundantly exported to Switzerland, Germany, the United States, Canada and other countries and regions, favored by domestic and foreign customers.
Material
Neodymium magnet, SmCo magnets , AlNiCo are often selected as mini magnetic material.
Some Sizes for Reference
0.5x0.5x0.5mm
0.2x0.2x0.2mm

Plating
Parylene is the often used as coating for mini magnets for it thin thickness and excellent oxidation/corrosion resistance performance. We have other coatings like NiCuNi. Small magnets can also be supplied in un-plated status so customers can have their special surface treatment on them.
With the industry's absolute leading edge, China Rare Earth Magnet Limited is specialized in precision machining and designing of various hard and brittle permanent magnet materials, and boasts rich experience in manufacturing high precision small neodymium magnets in ring shape with long hole and thin wall, disc shape and cubic shape. We are also able to customize magnets as per specifications or drawings from customers.
