Hangzhou Tengye Magnetic Materials Co., Ltd. is a neodymium magnet supplier in China. We are both manufacturer and exporter. Tengye Magnetic manufactures a variety of sintered neodymium magnets according to different shapes.

Sintered neodymium magnets are manufactured by powder metallurgy. They are manufactured by the raw materials such as iron, rare earth alloy, etc. being melted in a strip casting furnace, cast by a roller and rapidly cooled to form NdFeB ingots. These NdFeB ingots are pulverized by hydrogen and jet milled under the protection of nitrogen; the NdFeB powder is then sintered into dense blocks. The blocks are then heat-treated, ,machined to shape, surface coated and magnetized.
