Rare earth neodymium disc magnets 25x3mm are supplied with grade range from N35 to N52, a fully magnetized N42 neodymium disc magnet 25x3mm has magnetic force of 5.1kgs and has 1540 Gs central surface magnetic field. Our 25x3mm rare earth neodymium disc magnets are usually delivered with tolerance of +/-0.05mm and NiCuNi plated. If you need 25x3mm neodymium disc magnets used in high temperature, please choose the grade of H, SH, UH, EH and AH.
Working Temperature: The maximum working temperature of normal 25x3mm neodymium magnets is 80 degrees Celsius, while H, SH, UH, EH and AH series 25x3mm neodymium disc magnets can working under higher temperature.
Remanence: The Remanence(Br) of N52 neodymium disc magnets 25x3mm is up to 14.3-14.8KG. All other permanent magnet for sale have much lower remanence.
Magnetic Energy: The grade of neodymium magnets 25x3mm range from N35 to N52, which have magnetic energy range from 35MGOe to 52MGOe.
Corrosion Resistance: Waterproof coating is needed for neodymium disc magnet 25x3mm, otherwise it will oxidize soon.
