1. The circular 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 is commonly known as strong magnet or permanent magnet, because the magnetic properties of sintered Nd-Fe-B are far better than bonded Nd-Fe-B.
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 circular NdFeB magnets is common, including galvanizing, nickel plating, nickel plating, copper nickel, epoxy resin, electrophoresis, gold plating, etc.

Circular magnet characteristics
1. The round magnet has strong magnetic force, long-lasting and strong bearing capacity, and 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.
