Ferrite block magnets are widely used in magnetic separators, grates, filters, holding fixtures and educational products. Their corrosion resistance makes them suitable for food-grade and outdoor separation equipment.
We supply ferrite blocks from small sensor blocks to large separator magnets, magnetized across the thickness or in alternating pole arrays.

FAQ
Ferrite Block Magnets for Separation & Holding — FAQ
Can ferrite blocks be used in food separation?
Yes. Ferrite is inherently corrosion resistant and non-toxic, making it a common choice for magnetic separators and grates in food processing lines.
What magnetization patterns are available on blocks?
Through-thickness, through-length and alternating multi-pole (e.g., 2, 4 or 6 poles along the length) are all available depending on application.
Do you provide free samples for testing?
Yes, sample orders are welcome. Send your drawing or specification together with the intended application so our engineers can recommend the correct grade, magnetization direction and coating before we prepare samples.
Can the factory produce to my drawing with special tolerances?
Yes. We machine, grind and inspect to customer drawing tolerances. For sintered NdFeB the standard machining tolerance is ±0.05 mm and can be tightened to ±0.02 mm with diamond grinding where the geometry allows.
