Frequently Asked Questions

What is the difference between N52 and N42 magnets?

N52 has a higher maximum energy product (BHmax) than N42, meaning it is stronger magnetically. However, N42 typically has better temperature stability and is less brittle, making it more suitable for certain applications.

Can you customize magnet shapes and sizes?

Yes, we offer full customization including discs, blocks, rings, arcs, and complex geometries. We support CAD drawings and prototypes for OEM integration.

What coatings do you offer for NdFeB magnets?

We provide Ni-Cu-Ni, zinc, epoxy, gold, silver, rubber (NBR, EPDM), and Parylene coatings based on environmental requirements.

Do you provide magnetic assemblies?

Yes, we manufacture complete magnetic assemblies including holding systems, lifting magnets, sensor units, and motor components with housings, adhesives, and shielding.

What is the lead time for custom orders?

Typical lead time is 15–25 days after sample approval, depending on complexity and order volume. Stock items ship within 5–7 days.
