High-performance NdFeB criteria: Hcj(kOe)+(BH)max(MGOe)> >60. At present, according to the regulations of "China High-tech Products Catalogue (2006)", it is made by quick-setting belt throwing method. The sum of intrinsic coercivity Hcj(kOe) and maximum magnetic energy ((BH)max,MGOe) is greater than 60. It is used to make sintered NdFeB permanent magnet materials for medium, small and micro special purpose permanent magnet motors, sensors, magnetic resonance instruments, advanced audio equipment, etc, it is a high-tech product that our country focuses on encouraging and supporting the development. The industry defines products that meet the above requirements as high-performance NdFeB permanent magnet materials.
more practically, manufacturers in the market often do not distinguish between low-end and high-performance NdFeB according to such standards, but according to the demand differences of downstream products. Specifically, low-end NdFeB is mainly used in magnetic adsorption, magnetic separation, electric bicycles, luggage buckles, door buckles, toys and other fields, while high-performance NdFeB mainly refers to magnets used in various types of motors and speakers in the field of high-tech barriers, including energy-saving motors, automobile motors, wind power generation, advanced audio equipment, elevator motors, etc.
low-end NdFeB market: a large number of small and medium-sized enterprises disorderly competition, excessive supply. Because low-end NdFeB is easy to produce, the production entry threshold is low, the technology content is low, the industry production capacity is relatively scattered, and the product homogeneity is high, resulting in excess market supply, poor bargaining power of manufacturers, and excessive small and medium-sized NdFeB manufacturers Vicious competition, mainly by lowering labor costs and environmental protection costs to compete for market share, sales profitability is difficult.
statistics show that more than 100 small and medium-sized enterprises in China can only compete in low-end fields such as magnetic adsorption, magnetic separation, electric bicycles, and even luggage buckles, door buckles, and toys. The gross profit margin of sales is less than 10%. The annual production capacity of most enterprises is only tens of tons to hundreds of tons. Under the background of large fluctuations in raw material prices and rising operating costs, the living environment of small and medium-sized enterprises has further deteriorated. The high-end NdFeB market has a higher entry threshold in terms of technology, capital, talent or downstream enterprise certification.
high-end NdFeB industry entry barriers are high, mainly technical barriers, non-standard design and manufacturing barriers, capital barriers, customer stickiness, certification barriers and talent barriers.
