Countersunk magnet is also called countersunk magnet. Countersunk strong magnet is installed and fixed in the required position through screws. Generally, the size of countersunk hole magnet is represented by large D, D1 countersunk hole diameter, D2 straight hole inner diameter, and H thickness (height).
1. The material composition of countersunk hole NdFeB magnet is made of metal praseodymium neodymium, pure iron, ferroboron and some metal elements added 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.
Characteristics of countersunk hole Nd-Fe-B magnet
1. The Nd-Fe-B magnet with countersunk head hole has strong magnetic force, long-lasting and strong bearing capacity, and can absorb objects several times larger than itself.
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.
