Type: Permanent Composite: NdFeB Magnet Shape: ring Application: Speaker Magnet

The character designation of sintered NdFeB magnets is composed of NdFeB, the chemical symbols of neodymium, ferrum and boron,and two magnetic properties. The number in front of the solidus refers to the maximum magnetic energy product, symbol BH max and unit kj/m. The number after the solidus refers to one-tenth of magnetic polarization intensity coercivity, symbol Hcj and unit KA/m, rounded to the nearest integer.
Required Information for Quotation:
1. Intend application and Material.
2. Shape, size dimensions and tolerance level.
3. Material Characteristic (i.e. Br, bHc, iHc, BHmaxK)
4. Environmental conditions and Inspection sampling plan.
5. Magnetized or unmagnetized.
6. Magnetic Polarity and magnetized direction.
