Product Description

Specifications Neodymium permanent magnets

Grade: N33-N52 and so on

Coating:Zn,Ni,silver,gold,copper,epoxy

Widely used in different area.

Speaker Neo Magnets   Neodymium Iron Boron (NdFeB) magnet has high remanence, high coercive force, high energy product and high performance/cost ratio. It is easily formed into various sizes, widely used in motor, sensor, meter, sound device, magnetic separator, automobile, aviation, aerospace and other applications. It is prone to corrosion in humid environments, so it usually needs surface treatment according to customers' requirements. The coatings we can offer include: nickel, zinc, gold, silver, epoxy and parylene. Production Process Flowchart     Magnetic Characteristics
