SmCo Block Magnets
- Standard Size Range: L=1-130mm, W=0.5-130mm, T=0.3-90mm
- Maximum Block Dimensions: Rectangle: L130×W100×T50mm, Square: L130×W130×T40mm, Max Magnetization Direction: 100mm
- Minimum Block Dimensions: L1×W0.5×T0.3mm
Note: For block magnets, if you desire one large dimension, other dimensions must be proportionally reduced. Achieving multiple large dimensions with a thin thickness is not feasible due to the inherent brittleness of SmCo magnets. For dimensions exceeding the above-mentioned standards, consult our technical or sales team for optimal solutions.
