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, and widely used in motor, sensor, meter, sound device, magnetic separator, automobile, aviation 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.

Our quality policy is to keep improving, to be better. With an experienced team, we are continually improving our quality assurance system, cost accounting and quotation system, sales service system to satisfy our customers better.
We sincerely look forward to establishing long-term cooperation relationships with customers around the world!
