Common sourcing questions
What is a samarium cobalt magnet?
Samarium cobalt (SmCo) is a rare-earth permanent-magnet material. Hangda focuses on Sm₂Co₁₇ grades for applications that require magnetic performance, temperature resistance and stability.
How hot can Hangda SmCo magnets operate?
The published maximum temperature depends on the grade. XGS 26-T550 is listed at 550 °C, with 9–11 MGOe measured at 550 °C. The final safe operating point depends on geometry, the magnetic circuit, reverse field and exposure conditions.
Can Hangda manufacture to a customer drawing?
Yes. Hangda provides customized magnet shapes and magnetic assemblies. Share dimensions, tolerances, material requirements, magnetization direction, quantity and operating conditions for a technical review.
Which quality certification is available?
The supplied quality management certificate is for GB/T 19001-2016 / ISO 9001:2015 and covers R&D, production and sales of SmCo rare-earth permanent magnetic materials, and sales of magnetic materials. The certificate states an expiry date of 14 November 2027, subject to its ongoing validity conditions.
What should I include in an RFQ?
Include your application, preferred grade or required magnetic performance, operating temperature, drawing revision, dimensions and tolerances, magnetization direction, order quantity, destination and target delivery date.
