Special Shape SmCo Magnets
- Standard Size Range: W=3-130mm, H=1.5-100mm, L=1-130mm
- Maximum Special Shape Dimensions: W130×H40×L130mm, W80×H50×L130mm
- Minimum Special Shape Dimensions: W3×H2×L0.5mm
Note: For special shapes, if you desire one large dimension, other dimensions must be proportionally reduced to avoid breakage from SmCo's brittleness during assembly. For sizes exceeding the standards above, consult our technical or sales team for optimal solutions.
