Frequently Asked Questions

What is the difference between sintered and bonded NdFeB magnets?

Sintered NdFeB magnets are made by pressing and sintering neodymium powder under high temperature, resulting in higher magnetic strength and density. Bonded NdFeB magnets are made by mixing magnetic powder with a polymer binder and molding it, offering more complex shapes but lower magnetic performance.

Where are soft magnetic alloys mainly used?

Soft magnetic alloys are widely used in transformers, inductors, relays, sensors, magnetic shielding, and electromagnetic actuators in industries such as electronics, automotive, aerospace, and telecommunications due to their high permeability and low energy loss.

What are the advantages of soft magnetic alloys?

Soft magnetic alloys offer high magnetic permeability, low coercivity, low core loss, excellent temperature stability, and good corrosion resistance. These properties make them ideal for efficient energy transfer and signal processing in electronic devices.

Do you offer custom magnet shapes and sizes?

Yes, we support custom manufacturing of magnets in various shapes including arcs, rings, blocks, discs, and complex geometries. We also provide multi-pole magnetization and special coatings upon request.

What is the lead time for sample and bulk orders?

Sample orders are typically shipped within 7–10 days. Bulk production lead time ranges from 20 to 30 days depending on product complexity and order quantity. We provide production updates throughout the process.
