Basic Intro
              Sintered NdFeB Magnet
              Bonded NdFeb Magnet

The Sintered NdFeB magnet is the strongest permanent magnet nowadays. For their high remanence, high corrective force, high energy product, reasonable price / performance ratio and availability to different dimensions, they are especially suitable to the research and development of light and compact products with high performance.

For Debits surface is usually treated with some special methods. The surface treatment method include Zinc,Nickel,Tin,Silver,Gold plating,Phosphor and Spray Epoxy Resin etc.

DATOYO also can supply high grade like N50 and high working temperature such as N33AH and N35AH.
