SmCo5 Magnets(XGS6~XGS26)
(BH)max values of regular SmCo5 magnet are between 14 and 24MGOe. SmCo5 is made of only Samarium and Cobalt and exhibits better corrosion resistance and machinability.
Main applications:
1. Aerospace
Used for satellite attitude control, aircraft navigation systems and high-temperature motors, withstanding extreme temperatures (-270℃~350℃), ensuring stable operation in space environments, and strong radiation resistance.
2. Defense and military
Applied to missile guidance, radar systems and submarine motors, high coercivity prevents demagnetization, corrosion resistance adapts to the marine environment, and ensures long-term reliability of equipment.
3. Industrial motors and generators
Core components of high-temperature motors (such as electric vehicles and wind turbines), lightweight design improves energy efficiency, and maintains strong magnetic properties at high temperatures (operating temperature can reach 300℃).
4. Medical equipment
MRI, micro-surgical robots and implantable devices, non-toxic materials meet biosafety standards, and magnetic field stability supports precision imaging and operation.
Customization process
Provide one- stop service from design to product application.
1. Demand communication:
The customer contacts the salesperson and details the customized expectations of SmCo Magnets, such as magnetic properties, size, shape, application and special properties, etc. The salesperson will record them accurately and start the customization process.
2. Solution design:
Select raw materials, determine processes, set quality control, prepare technical drawings and performance reports according to needs, submit them to customers for review, and build a high-quality solution together.
3. Sample production:
The solution is determined, the best SmCo materials are selected, and samples are carefully made through multiple precision processes to meet the needs.
4. Sample testing and feedback:
The samples are sent to professional laboratories for high-precision testing of magnetism, size and other aspects, and detailed reports are given to customers to help them evaluate.
5. Batch production:
If the samples are qualified, they are made in batches according to the order quantity, strictly abide by the process and quality control, and ensure that each batch is consistent, stable and efficient.
6. Packaging and delivery:
After production, the products are professionally packaged and delivered according to customer requirements, with quality documents, instructions and after-sales information attached, and considerate service to the end.

FAQ
Q1: What are the advantages of Shanghai Yangci in the manufacturing of samarium cobalt magnets?
A1: Shanghai Yangci has been deeply involved in the field of samarium cobalt magnets for many years, and its main advantages include:
Mature process: using industry-recognized sintering technology and precision processing equipment to ensure that magnetic properties (such as coercivity and remanence) meet international standards (such as ISO 9001).
Strict quality inspection: from raw material procurement to finished product delivery, the entire process follows ASTM/IEC specifications, and the product qualification rate is stable at more than 99%.
Flexible customization: It can produce non-standard sizes, special coatings (such as nickel-copper-nickel composite coatings) and multi-pole magnetization products to meet the needs of medical equipment, industrial motors and other scenarios.
Q2: How to ensure the high temperature stability of samarium cobalt magnets?
A2: Samarium cobalt magnets have excellent temperature resistance. We further ensure their performance in the following ways:
Material selection: Mainly promote Sm₂Co₁₇ formula, Curie temperature reaches 850°C (industry high-end standard), and magnetic loss is less than 5% under -50°C to 300°C environment.
Process optimization: Vacuum sintering combined with segmented heat treatment reduces material internal stress and improves oxidation resistance.
Actual test: Each batch of products undergoes high temperature cycle test (300°C/500 hours) and provides third-party test reports.
Q3: Do you accept small batch customization?
A3: Yes, we provide flexible order services:
Small batch production: The minimum order quantity can be as low as 1 piece, and the sample delivery cycle is about 10-15 working days.
