Powerful NdFeB special-shaped magnets

Details of powerful NdFeB special-shaped magnets

Special-shaped magnets specifically refer to magnets with irregular shapes, which mainly serve specific needs. Injection molded magnets are very suitable for special-shaped magnets, but the maximum energy product (BH)max of conventional isotropic injection-molded NdFeB molded magnets is limited to 60kJ/m3, which cannot meet the needs of most special-shaped magnets.

The company focuses on the customization of special-shaped magnet manufacturers. It can customize special-shaped NdFeB magnets with any specifications and performance. If you need quotations and proofing of special-shaped magnets, you are welcome to send us drawings and samples.

1. The material composition of special-shaped magnets is made of metal praseodymium and neodymium, pure iron, and ferroboron in a certain proportion and then added with certain metal elements through multiple processes.
2. NdFeB is subdivided into sintered NdFeB and bonded NdFeB. Commonly known as powerful magnets or permanent magnets, sintered NdFeB magnets are because the magnetic properties of sintered NdFeB magnets are far better than those of bonded NdFeB. Iron boron.
3. Preparation process: Ingredients - Smelting - Powdering - Pressing - Sintering (sintered NdFeB) - Processing - Magnetization to make finished products. The processing process includes: grinding, slicing, wire cutting, drilling, drilling, electroplating, etc. .
4. Surface treatment of curved NdFeB magnets, common ones include galvanizing, nickel plating, nickel-copper-nickel plating, epoxy resin, electrophoresis, gold plating, etc.

Characteristics of special-shaped magnets
1. The special-shaped magnet has strong magnetic force, long-lasting force, and strong load-bearing capacity. It can absorb and absorb items that are several times larger than its own volume.
2. The material is environmentally friendly, has stable magnetic force and strong corrosion resistance. It can generally pass the salt spray test for 96 hours.
3. Resistant to high and low temperatures, made of high-quality rare earth NdFeB, ferrite and other materials, with multiple temperature configurations available from -50°C to 260°C.

Correct separation method of magnets
1. Slide a magnet off the top of the stack.
2. Once off the stack, carefully begin lifting the magnet.
3. Suction from a long distance, please be careful of the magnet breaking and pinching your hands.
