B2B Buying Guide

Ferrite magnet details buyers should confirm before quotation.

Share these details with CIYI to reduce back-and-forth communication and get a more practical sourcing reply.

Common Shapes

Arc / tile magnets for motor and fixture applications
Block, bar, disc, ring, cylinder, and hole magnets

Common Grades

Y25, Y30, Y30BH, Y33, Y35 and higher ferrite grades
Final magnetic value should be confirmed by drawing and production batch

Magnetization

Axial, radial, multipole, or custom magnetization by application
Motor arc magnets should confirm pole direction clearly

Surface / Finish

Natural ferrite surface, ground surface, or custom treatment by request
Confirm tolerance and appearance requirement before sampling

Quote Tips

For a faster quote, send shape, size, grade, quantity, magnetization direction, tolerance, packaging method, and target use. Price, MOQ, and lead time are confirmed by order details.

Magnetic Grade Table

Ferrite / oxide magnet grade reference.

Typical magnetic ranges for sourcing reference. Final values should be confirmed by grade, drawing, and production batch.
