Professional Strontium Ferrite Arc Magnets for Industrial & Automotive Motors
Custom Multi-Pole Permanent Magnets with High Temperature Resistance
Product Overview
Strontium ferrite arc magnets are cost-effective, high-performance permanent magnet solutions optimized for motor assemblies. Manufactured from high-quality strontium ferrite material, these magnets offer excellent magnetic stability, corrosion resistance, and long-term durability, making them ideal for both industrial and automotive motor designs.
Available in FB9B and FB12B grades, these arc magnets can be customized in shape, size, and magnetization pattern (2-pole or multi-pole configurations). With a maximum operating temperature of 250°C and a residual magnetic flux density of 450mT, they deliver consistent performance under demanding conditions, even in elevated-temperature environments.

Frequently Asked Questions
Order Information Requirements
We will help you with your order. Usually we ask for the following information:
- Product material, size, grade, surface coating, quantities required. If available, provide a sketch or drawing with dimensions and tolerances
- Delivered magnetized or unmagnetized? Magnetization direction?
- Information on intended application and usage
Can you do OEM and ODM?
OEM and ODM are acceptable. Please inform us of your requirements for reference.
What about the sample lead time and charge?
For OEM or ODM projects, it typically takes 1-2 weeks to calculate charges. For available or in-stock items, samples are shipped within 5-10 days. Final charges depend on your confirmation of the project draft.
How can I place an order?
You can contact us by email with your order details or place orders online.
What's the order procedure?
First, we discuss order and production details via email. Then we issue a Proforma Invoice for your confirmation. Full payment or deposit is required before production begins. Production typically takes 15-25 days for non-stock items. Before completion, we coordinate shipment details and balance payment. After payment settlement, we prepare your shipment.
How can I pay you?
After confirming our PI, we request payment via T/T (HSBC bank), PayPal, or Western Union. L/C, D/A, and D/P are also available.
Can we visit your factory?
Factory visits are highly appreciated. We will send an invitation once your schedule is confirmed.
