Sintered neodymium magnet mainly comprised of neodymium, iron and boron is the third generation of the rare-earth permanent magnets, sintered NdFeb is the strongest permanent magnets in the world up to date

With excellent properties of high remanence, coercivity and maximum energy product:

N35/N38/N40/N42/N45/N48/N50/N52 (maximum operational temperature: 80°C)

N35M/N38M/N40M/N42M/N45M/N48M (maximum operational temperature: 100°C)

N35H/N38H/N40H/N42H/N45H/N48H (maximum operational temperature: 120°C)

N33SH/N35SH/N38SH/N40SH/N42SH (maximum operational temperature: 150°C)

N28UH/N30UH/N33UH/N35UH/N38UH (maximum operational temperature: up to 180°C)

N28EH/N30EH/N33EH/N35EH (maximum operational temperature: up to 200°C)

N30AH/N33AH/N35AH (maximum operational temperature: up to 230°C)

Outstanding product:

High performance: N52/N48M/48SH/42UH/38EH/33AH

High working temperature: AH series with 40k Oe super-high coercive force can replace SmCo magnets successfully

High consistency: CPK of Br and Hcj are much higher than 1.67 the consistency of surface magnetic field and magnetic flux can be controlled with ±1%

High anti-corrosion: sale spray test and humid heat test of the high anti-corrosion coating could be more than 1,000 hours

Applications:

Loudspeakers, motor assemblies, windmill, home appliance, acoustics, communication equipment, toy, car, servo, step, DC, linear motor and microphone
