Grade 34 SmCo Magnets

Grade 34 SmCo Magnets are deployed in high-tech and harsh-environment sectors:
Aerospace/Defense：Satellite gyroscopes, missile guidance systems, and jet engine sensors (FAA-compliant fuel systems).
Medical：MRI gradient coils (0.1 T/m precision) and surgical robotics due to biocompatibility and thermal stability.
Energy：Downhole drilling sensors (175°C+ environments) and wind turbine generators.
Electronics：Traveling wave tubes (10–40 GHz operation) and high-temperature micro-motors.

1. Stable at High Temperatures
Grade 34 SmCo Magnets operate up to 350°C with a Curie temperature of 800–850°C. Maintain stable magnetic output in extreme heat — ideal for aerospace sensors, industrial monitoring, and high-temperature motors.

2. Strong Magnetism in Compact Sizes
Energy product: 32–34 MGOe (256–272 kJ/m³). Delivers strong magnetic force in small structures — helps reduce component size and weight for space-constrained applications.

3. Naturally Corrosion-Resistant
Unlike neodymium magnets that require protective coatings, SmCo magnets resist corrosion by nature. No extra plating needed — reliable in moisture, chemicals, and long-term exposure.

4. Reliable in Extreme Environments
Performs consistently from low temperatures up to 350°C. Built for aerospace, energy, and industrial applications with wide temperature swings and environmental stress.

Custom Shape and Dimension
Manufacturers can provide customized Grade 34 SmCo Magnets according to customer drawings and application requirements.
Available designs include:Block magnets, disc magnets, ring magnets, arc magnets.

Custom Coating Solutions
Although Grade 34 SmCo Magnets have natural corrosion resistance, additional surface treatments can be provided for special environments.
Nickel (Ni)​​: Enhances solderability for PCB integration and provides a polished finish for medical devices
Parylene​​: Used in vacuum or biocompatible environments (e.g., MRI components) to prevent particulate shedding
Epoxy/Stainless Steel Cladding​​: Protects against mechanical wear in industrial settings (e.g., oil drilling sensors)
Gold/Zinc​​: For high-frequency applications (e.g., microwave tubes) requiring low electrical resistivity

Custom Magnetization Direction
According to product structure, manufacturers can provide different magnetization methods. Axial magnetization, radial magnetization, multi-pole magnetization.

Packaging

Standard packaging includes individually wrapped magnets using anti-static foam or plastic materials, then placed into cartons or wooden crates.
For bulk orders, magnets are palletized with moisture-resistant barriers to improve storage stability. Vacuum-sealed packaging options are available for special requirements.
Shipping packaging can be customized according to customer requirements and complies with relevant transportation regulations.
Packaging options include: Anti-static foam packaging, plastic protection, cartons, wooden crates, pallet packaging.
For defense-related shipments, packaging can comply with ITAR requirements.

Maintaining Magnetic Performance in High Temperature Environments
Many industrial customers face magnetic performance degradation when using standard magnets in high-temperature applications. Grade 34 SmCo Magnets provide stable performance up to 350°C, helping reduce equipment failures caused by thermal conditions.

Reducing Maintenance Requirements
Customers operating equipment in humid or corrosive environments often require additional protective measures. The intrinsic corrosion resistance of Grade 34 SmCo Magnets reduces dependence on surface protection and improves product reliability.

Supporting Compact Equipment Design
Modern industrial equipment requires smaller and lighter components. The high energy product of Grade 34 SmCo Magnets allows manufacturers to achieve strong magnetic performance while maintaining compact designs.

1. What are Grade 34 SmCo Magnets?
Grade 34 SmCo Magnets are high-performance samarium cobalt permanent magnets from the Sm₂Co₁₇ series, designed for applications requiring strong magnetic performance and high-temperature stability.

2. How does Grade 34 SmCo compare with NdFeB magnets?
Grade 34 SmCo Magnets generally have lower magnetic strength than high-grade NdFeB magnets, but they provide better temperature resistance and corrosion resistance, especially in environments above 300°C.

3. Can Grade 34 SmCo Magnets be customized?
Yes. Manufacturers can customize dimensions, shapes, coatings, magnetization direction, and packaging according to OEM requirements.

4. Why are Grade 34 SmCo Magnets more expensive?
The higher cost is mainly due to the use of samarium and cobalt materials, along with complex sintering and aging manufacturing processes.

5. Can Grade 34 SmCo Magnets operate in low-temperature environments?
Yes. Grade 34 SmCo Magnets can maintain stable performance in cryogenic environments, with operating capability from approximately -65°C to 350°C.

6. How should Grade 34 SmCo Magnets be machined?
Because SmCo magnets are hard and brittle, machining usually requires diamond tools or EDM processing.

7. What information should buyers provide for quotation?
B2B buyers should provide magnet size, shape, magnetic requirements, operating temperature, coating requirements, quantity, and application environment.

8. Can suppliers provide samples before mass production?
Yes. Sample production and testing are commonly available before bulk manufacturing.

9. Do Grade 34 SmCo Magnets need coating?
Generally, they do not require coating due to their corrosion resistance, but special coatings can be added for specific applications.

10. Which industries commonly purchase Grade 34 SmCo Magnets?
Major industries include aerospace, defense, medical equipment, energy systems, electronics, and high-temperature industrial equipment.
