N40H Strong Ring Magnets Diametrically Magnetized , Sintered Ring Neodymium Magnets

Strong N40H Neodymium Ring Magnets Plating NiCuNi Diametrically Magnetized

Neodymium magnet (Nd-Fe-B) is one of the highest property and strongest permanent magnet by now, are made through powder metallurgy manufacturing techniques. They are mainly composed of neodymium(32%), iron(64%), boron(1%), and a few quantity rare earth material, such as Dy, Tb, Co, Nb, Ga, Al, Cu,etc.

Advantage:  1.Neodymium Ring magnet is regarded as “Magnet King” due to its recorded high remanence, coercive force and maximum energy product.

2. With Neodymium magnet rapid development, many high-tech products were developed. Especially its application in motors makes products miniaturization and micromation.

3. At the same time, because of its high remanence, coercive force and maximum energy product, this type magnet is widely used in servo motor, flat brushless motor, step motor, IT products, Nuclear Magnetic Resonance, speaker and other products.

4. Neodymium magnet is easily rust and oxidated, so their surface must be plated Zn, Ni, Silver, Gold or made phosphor and epoxy treatment.

Specifications

Attributes of Neodymium Ring Magnet

• Very high resistance to demagnetization
• High energy for size
• Good in ambient temperature
• Moderately priced
• Material is corrosive and should be coated for long term maximum energy output
• Low working temperature for heat applications, but higher levels of heat resistance materials are being introduced periodically
