AlNiCo Magnets Prospects

Manufacturers must ensure the quality of samarium cobalt magnets

SmCo magnet products are manufactured by the processing factory, but the magnet manufacturers believe that the quality of samarium cobalt magnet is jointly checked by both sides. Why do you say it, because the customer's standard is the driving force of manufacturers efforts, no customer supervision can not fake and shoddy products than the side.

Why is it like that? This will be from the samarium cobalt magnet production and processing of the entire process to be analyzed. Under normal circumstances, the samarium cobalt magnet before processing, to multi-project use of bolt occasions for accurate and specialized measurement, in the measurement process requires the use of specialized equipment, otherwise the production of samarium cobalt magnet is not up to trouble The

Customers and production and processing companies to conduct a detailed communication, the requirements of their own parameters to make it clear. And then samarium cobalt magnet manufacturers can be in accordance with the requirements of customers for production and processing. From the choice of raw materials, the middle of each production process, until the final quality testing, need to follow the standard process of standard operation. In addition, in the transport process can not ignore the protection of samarium cobalt magnet products.

In the acceptance process, the customer in accordance with the requirements to check the quality of samarium cobalt magnet products, which also played a supervisory role. Only the two sides communicate with each other in order to allow the quality of samarium cobalt magnet to be better guaranteed.

Present Situation and Development Prospect of Magnetic Materials in China

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 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.
