Special shaped magnets refer to magnets with irregular shapes, which mainly serve specific needs. Injection molded magnets are very suitable for special-shaped magnets, but the large energy product (BH) max of conventional isotropic injection molded NdFeB magnets is limited to 60kj/m3, which cannot meet the needs of most special-shaped magnets.
1. The special-shaped magnet material is made of praseodymium, neodymium, pure iron, ferroboron and some metal elements in a certain proportion through multiple processes.
2. Nd-Fe-B is subdivided into sintered Nd-Fe-B and bonded Nd-Fe-B. sintered Nd-Fe-B magnets are commonly known as strong magnets or permanent magnets, because the magnetic properties of sintered Nd-Fe-B magnets are far better than bonded Nd-Fe-B magnets.
3. Preparation process: batching - smelting - pulverizing - molding - sintering (sintered Nd-Fe-B) - processing - magnetization to make finished products. The processing process includes: grinding, slicing, wire cutting, drilling, casing, electroplating, etc.
4. The surface treatment of arc-shaped Nd-Fe-B magnets is common, including zinc plating, nickel plating, nickel plating, copper nickel, epoxy resin, electrophoresis, gold plating, etc.

Special magnet characteristics
1. The magnetic force of the special-shaped magnet is strong, durable and has strong bearing capacity. It can absorb objects several times larger than its own volume.
2. Environmental friendly material, stable magnetic force and strong corrosion resistance. Generally, it can pass the salt spray test for 96 hours.
3. High and low temperature resistance, using high-quality rare earth neodymium iron boron, ferrite and other materials, -50 ° C to 260 ° c various temperature configurations are optional.
