SmCo Disc & Rod Magnets
- Standard Size Range: D=1-130mm, T=0.3-120mm
- Maximum Cylinder Dimensions: D130×T40mm, D80×T120mm
- Minimum Cylinder Dimensions: D1×T0.3mm
Note: Due to the inherent brittleness of SmCo material, extremely large diameters and thin thicknesses may compromise the integrity of the magnet during assembly. For larger dimensions, consult our technical or sales team for specialized advice.
