Neodymium disc/cylinder magnets are round coin-shaped neodymium magnets of varying diameter and thickness.
As the most strongest magnet material, Neodymium Iron Boron (NdFeB) alloy provides around 1.5-4 times pull force per unit volume compared to other magnet materials such as SmCo and AlNiCo. This outstanding performance makes Neodymium magnets the most widely used for many consumer, commercial and technical applications in the world.
EPI Magnets not only produces many kinds of dimensions/grades/ magnetization directions for Neodymium disc/cylinder magnets, but also provides different coating options for various working environments and economic purpose.
Materials: Sintered Neodymium Iron Boron.
Dimensions: Customized. Generally, diameter is from 1/16″ to 4″ and length is also from 1/16″ to 4″.
Tolerance: Generally, the tolerance is +/– .004″ for all dimensions. Tighter tolerance is also available.
Grades: Here're the NdFeB Magnets Grades we supply.
Type | Suffix Meaning | Grades | Maxinum Working Temperature |
---|---|---|---|
N | (No suffix) | N27, N30, N33, N35, N38, N40, N42, N45, N48, N50, N52, N54 | 80 deg C/175 deg F |
NM | M: Medium Grade | N30M, N33M, N35M, N38M, N40M, N42M, N45M, N48M, N50M, N52M | 100 deg C/212 deg F |
NH | H: High Grade | N30H, N33H, N35H, N38H, N40H, N42H, N45H, N48H, N50H | 120 deg C/248 deg F |
NSH | SH: Super High Grade | N30SH, N33SH, N35SH, N38SH, N40SH, N42SH, N45SH, N48SH | 150 deg C/302 deg F |
NUH | UH: Ultra High Grade | N28UH, N30UH, N33UH, N35UH, N38UH, N40UH, N42UH | 180 deg C/356 deg F |
NEH | EH: Extreme High Grade | N28EH, N30EH, N33EH, N35EH, N38EH | 200 deg C/392 deg F |
NAH | AH: Astronomical High Grade | N33AH | 230 deg C/446 deg F |
Tips: SmCo magnets perform better when operation temperature is above 150 ℃ and cost less than UH, EH and AH grades. We suggest you choose SmCo magnets in high temperature.
Coating/Plating: Customized.
Nickel (Ni-Cu-Ni), Zinc (Zn), Gold (Ni-Cu-Au), Epoxy, Ni-Cu-Epoxy, Plastic, Teflon® (PTFE), Xylan® (PTFE), Everlube-6155®.
1.Axially Magnetization: Neodymium Disc/Cylinder Magnets are magnetized along their geometric axis.
2.Diametrically Magnetization: Neodymium Disc/Cylinder Magnets are magnetized across their diameters.
