Ring Sintered NdFeB magnet for speaker

Sintered NdFeB

Brief

Sintered NdFeB Magnet Come out from the early 1980s. Its main component is Nd2Fe14B with

high magnetic performance. Because of bad anticorrosion, the surface of magnet need handling with various coating for some especial applications from various clients, such as Zn ,Ni, Au ,Epoxy so on.

Characteristics

1.      It has higher magnetic performance. Its maximum energy density ----(BH)max is over 10 times as high as that of ferrite magnet.

2.      it has good mechanical property, which is suitable for various processing, such as abrasive cutting, linear cutting and boring so on.

3.      Its maximum working temperature can come up to 250 ℃,while it depends on the temperature more.

4.      Because of bad anticorrosion, the surface of magnet need handling with various coating or electroplating for some especial applications.

Advantage

1.We are gradually carrying out and improving the advanced production process, which adopt the production method of “Fully automatic phosphating------hydriding, Jet milling ------Closed pressure type ------continuous sintering”.

2. We have large-scale advanced processing production lines. With Processing machines over 3,000 sets .No problems for various large orders

3.We can make ultra-small and ultra-large magnets, such as Φ1mm or Φ180mm etc.   

4.we have the most advanced electroplating and surfacing lines in China, including chemical plating, electroplating, compound plating, organic spraying and phosphating

5.we adopt advanced low oxygen process to produce premium anti-corrosion magnets and high performance NdFeB products (higher than N45) in bulk. And we can produce isotropic and anisotropic NdFeB ring magnets with radial magnetization .

6.Established ISO-based quality system, implemented 6Sigma quality management system, optimized production process and reduced product cost.

7.Advanced physical and chemical lab, and strong R&D team guarantee the production of high performance and high quality products.

8. We have several senior material experts conducting research on related topics, while cooperating with famous scientific research institutes. 

Quality System

With its own strict quality control system and advanced detection equipment, MAS MAGNETICS has been successively certified by ISO9001, ISO9000 and TS16949 quality system.
