Product Description

The character designation of sitered 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 magnetc 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.
7. Quantity per year and per shipment...
8. Special request method for packing.

PRODUCT ADVANTAGE:
1. The superlative strength magnets at present.
2. Used in mostly in smaller, lightweight and thinner design products.
3. The average energy product's cost is comparable to substitute the ferrite magnet.
4. Prompt Delivery and Competitive Price.
