First, the status of magnetic materials industry

1, product output and output value is not suitable

China's magnetic materials industry has begun to take shape in the production, but in the high-end products have not yet formed a strong international competitiveness.

2, magnetic product performance is low

The production performance of NdFeB magnets is generally around N35 (magnetic energy product of 35MGOE), N40 above and high coercivity grade N38H. N32SH only a few companies can produce. Foreign launch of the new brand has reached N50, N48H.

3, the production process and equipment is relatively backward

China's total sales of magnetic materials equipment reached 143 million yuan, to provide complete sets of production equipment. Therefore, domestic enterprises should try to use a high degree of automation of continuous production lines, reduce the impact of human factors to ensure product consistency.

Second, the development direction of soft ferrite

Currently the most widely used soft ferrite, according to the use and materials can be divided into: manganese zinc power ferrite materials, communications and electromagnetic compatibility (EMC) with manganese zinc high permeability ferrite materials, deflection coil with manganese Ferrite materials, radio frequency broadband and electronic interference (EMI) suppression of nickel zinc ferrite materials and other four categories. Materials to further high-frequency, high permeability and low loss development, that is, two high and one low direction. The device is developed in the direction of miniaturization, chip and surface mount.

Permanent ferrite material

As the demand for high-grade magnets such as automobiles and computers increases, the proportion of high-grade permanent ferrite in China will rise rapidly. It is expected that the proportion of Y30H-1 series of high-grade products will increase from 40% in 2000 to over 60% (about 126,000 tons) in 2005, and the output of Y30H-2 series of high-grade products can reach 10 % (About 2.13 million tons), the overall export volume increased to 50% or more.

NdFeB magnets

Due to the abundant raw material resources, cheap labor and huge application market, NdFeB magnets have many advantages in China. With the advent of the patent expiration period, "15" period to be a greater development is certain. In addition to the middle and low products steadily occupied the market, focusing on the development of high-end products, material performance to N45, N38H and N32H, the total output will reach 10,000 tons.

China's magnet industry in the 21st century with its own advantages, will become the world's magnetic material power.
