Neodymium magnet, also known as NdFeB magnet, is an alloy formed by neodymium, iron and boron (Nd2Fe14B). Rare earth is used as the raw material for the production of NdFeB permanent magnet materials, and the raw materials always account for more than 70% of the production cost of NdFeB processing enterprises. In the application field, Nd-Fe-B permanent magnet materials are widely used in energy-saving air conditioning, energy-saving elevator, consumer electronics, wind power, Automotive EPS, new energy vehicles and other fields. In recent years, the NdFeB recycling industry, as a part of the recycling economy of renewable resources, has been in the rising stage. Especially with the implementation of the mandatory production plan, the production of rare earth raw ore separation enterprises has been limited, the development of NdFeB waste recycling industry has risen explosively, and the medium rare Tianma came into being.

Zhongxi Tianma mainly produces rare earth oxides such as praseodymium and neodymium oxide, dysprosium oxide, terbium oxide and gadolinium oxide.

Praseodymium neodymium oxide is the main raw material for the production of high-performance Nd-Fe-B permanent magnet materials. It is widely used in electronics, electric machinery, medical devices, hardware machinery, aerospace and other fields;

Dysprosium ferroalloy made from dysprosium oxide is mainly used in optical and magnetic recording materials, nuclear fuel diluents, etc;

Terbium dysprosium iron giant magnetostrictive material made of terbium oxide has the conversion function of electromagnetic energy and mechanical energy. It is an important energy and information conversion material, especially the important material of sonar transducer. It is an important military strategic material.
