Answers to Frequently Asked Questions

1.Can you customize permanent magnets according to specific requirements?
Sure. Custom made available.
2.What are the temperature and corrosion resistance properties of your magnets?
Max working temperature and corrosion resistance properties are based on different materials and grade, The maximum working temperature of alnico permanent magnet is more than 550 ° C, Samarium cobalt magnet is more than 500° C and ferrite magnet is about 250 ° C , Neodymium magnet is about 60-260° C and rubber magnet are about 100° C , but the actual value will still vary according to the size and shape of the material. AlNiCo magnets, Ferrite magnets and SmCo5 magnets have good corrosion resistance properties, SM2CO17 composition have some iron s, which can easily rust under harsh conditions. Therefore, it is necessary to electroplate the magnet. NDFEB magnets have poor corrosion resistance, and their finished products generally require electroplating treatment, such as NICUNI, ZN, EPOXY plating, etc.
3.How do you ensure the quality of your permanent magnets?
In order to ensure the quality of permanent magnets, the factory strictly follows the corresponding ISO or ts16949 quality management system for inquiries, quotations, order reviews, raw material procurement, and production process control.
4.What is the typical lead time for ordering permanent magnets?
Normally, our delivery date is 21-30 days
5.Do you provide technical support for integrating permanent magnets into our products?
Yes, we can provide technical support for integrating permanent magnets into your products. Permanent magnets are widely used in various applications, and proper integration is crucial for achieving optimal performance.

7.What certifications do your permanent magnets comply with?
Our permanent magnets comply with various certifications depending on the specific type and application. Some common certifications for permanent magnets include ISO 9001, ISO 14001, 45001,RoHS (Restriction of Hazardous Substances), and REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals). These certifications ensure that our magnets meet international quality standards, environmental regulations, and restrictions on hazardous substances. If you have specific certification requirements or need more detailed information, please let us know, and we will provide you with the relevant details.
8.What is your minimum order quantity for magnets?
Our minimum order quantity for magnets may vary depending on the type, size, and specific requirements. Generally, for standard sizes and types of magnets, the minimum order quantity is typically around 100 to 1000 pieces. However, for customized or special magnets, the minimum order quantity may be higher. We understand that every customer's needs are unique, so please provide us with your specific requirements, and we will do our best to accommodate your needs and provide you with the most suitable solution.
