Neodymium Disc Magnets 15x3mm

The round magnets 15x3mm are made of N45 neodymium magnetic material, which have central surface magnetic field of 2544 Gauss and 2.9kgs magnetic strength. N45 neodymium disc magnets must be used under the temperature of 80℃. Neodymium disc magnet 15*3mm is small sized magnet with strong force, higher grades of N48, N50 or N52 are available if you need stronger 15*3mm neodymium disc magnets.

Characteristics Of 15x3mm Neodymium Disc Magnets N45

Remanence(Br): The remanence(Br) of N45 15x3mm neodymium magnets is around 13500 Gs.

Hcj: N45 sintered neodymium disc magnets 15x3mm is over 12 Koe(955 KA/m).

Magnetic Energy/(B-H)max: The neodymium disc magnets 15x3mm have 45 MGOe magnetic energy,the higher magnetic energy is available for N45,N50 and N52.

Working Temperature: 15x3mm disc neodymium magnets N45 can not withstand higher temperature than 80℃.

Corrosion Resistance: Neodymium magnet are not rust-proof magnet,Ni-Cu-Ni is the most popular coating for 15x3mm neodymium magnet discs.
