    Product Description

    We are a well-known manufacturer, exporter, supplier, trader, and distributor of high quality NdFeB Rare Earth Magnet. This type of magnet can withstand high working temperature up to 230 degree centigrade. Moreover, we have advanced manufacturing capabilities owing to which we are able to produce NdFeB Rare Earth Magnet in various shapes such as ring, cylinder, disc, half-ring, arc (segment), and many others as per the client requirement. It is widely appreciated for outstanding anti-corrosive property and quality consistency. Further, we have magnetized it from comprehensive directions such as axial, diametrical, radial, multi-poles, and others. On special request from customers, we can custom magnetize this type of rare earth magnet according to the preferences.
