Customized High-Quality SmCo Magnets

Stanford Magnets can supply a wide range of customized Samarium Cobalt Magnets according to requests.

* Stanford Magnets can help optimize performance and cost with SmCo magnets in grades from 16 to 32 MGOe and temperatures up to 350°C/662°F.

SmCo rare earth magnets are often used in high-temperature applications needing high magnetic performance and where magnetic stability over a wide range of temperatures is important.

Stock Samarium Cobalt magnets are also available to reduce development and production lead times.

SmCo Magnets Description

Samarium Cobalt Magnets are another type of permanent magnet. A big advantage of SmCo magnets is that they can operate at temperatures up to 300 degrees Centigrade.

SmCo Magnets Specifications

Available Grades of Samarium Cobalt Magnets

Related: SmCo Magnets Grade Info

Many grades of Samarium Cobalt exist to support a variety of industrial and commercial applications. The range of Samarium Cobalt Magnet grades is typically 16 to 32 MGOe. These ranges allow for balancing cost, magnetic performance, and operational temperature resistance.

Corrosion Resistance

Related: SmCo Magnets Coating Info

SmCo Rare Earth magnets are very resistant to corrosion and do not normally require any surface treatment.

Temperature Effects

Samarium Cobalt Magnets can operate at temperatures up to 500°F (260°C), making these rare earth magnets ideal for high heat applications.

Magnetization Options

Although most commercial magnets are anistropic, which means they have a preferred direction of magnetization, various pole configurations can be achieved without conflicting with a Samarium Cobalt Magnet’s orientation.

Compliance and Intellectual Property Considerations

Samarium Cobalt Magnets manufactured by Stanford Magnets are compliant with Intellectual Property Rights, Environmental Restrictions, and Conflict Mineral usage.

SmCo Magnets Handling and Storage

SmCo Magnets are very strong and brittle, requiring appropriate handling and packing to ensure safety and prevent damage.

SmCo Magnets Manufacturing Methods

Samarium Cobalt Magnets are typically manufactured by a powdered metallurgical process utilizing rigid steel or rubber molds.

SmCo Magnets Applications

SmCo Magnets are widely used in applications in which high operating temperature and high corrosion and oxidation resistance are crucial.

Why Choose Us


What are custom samarium cobalt magnets?
Custom samarium cobalt magnets are specially designed and manufactured to meet unique specifications for size, shape, magnetic orientation, and strength, tailored for specific applications that standard magnets cannot accommodate.
Why choose samarium cobalt for custom magnets?
Samarium cobalt magnets offer several advantages, including high magnetic strength, exceptional temperature stability (with operating temperatures up to 300°C), and resistance to oxidation without the need for protective coatings. These properties make them ideal for aerospace, military, high-temperature industrial applications, and medical devices.
Can the shape and size of samarium cobalt magnets be customized?
Yes, samarium cobalt magnets can be customized into a wide variety of shapes and sizes, such as discs, blocks, rings, cylinders, and more complex geometries. However, the material's brittleness requires careful handling and machining.
What are the limitations when customizing samarium cobalt magnets?
The main limitations are related to the material's brittleness, which makes it challenging to machine into complex shapes without risking damage. Additionally, samarium cobalt magnets are more expensive than other types, such as neodymium or ferrite magnets, due to the cost of raw materials.
What are some common applications for custom samarium cobalt magnets?
Custom SmCo magnets are used in various high-performance applications, including aerospace and defense systems, satellite systems, medical instruments requiring high magnetic fields in compact spaces, motors and generators in extreme temperatures, and sensor systems.
How do I choose the right grade of samarium cobalt magnet?
Samarium cobalt magnets come in different grades, indicating their maximum energy product and temperature stability. The choice of grade depends on the application's specific magnetic strength and temperature requirements. Manufacturers can provide guidance on selecting the appropriate grade for your needs.
What are the manufacturing processes for custom samarium cobalt magnets?
The manufacturing process typically involves powder metallurgy, including sintering and pressing the samarium cobalt alloy into a desired shape, followed by a heat treatment process. Precision machining may be used for final shaping, given the material's brittleness.
Can the magnetic orientation of samarium cobalt magnets be customized?
Yes, custom samarium cobalt magnets can be magnetized in various orientations during the manufacturing process, including axial, diametrical, radial, and multi-pole configurations, to suit specific application requirements.
What coatings are available for custom samarium cobalt magnets?
Although samarium cobalt magnets have excellent corrosion resistance and often do not require coatings, they can be coated for additional protection or aesthetic reasons. Common coatings include epoxy, nickel, zinc, and others.
How should custom samarium cobalt magnets be handled and stored?
Despite their strength, SmCo magnets are brittle and should be handled carefully to avoid chipping or breaking. They should be stored in a dry, mild environment, and measures should be taken to minimize the risk of snapping together or coming into contact with ferrous materials.
What are the lead times for custom samarium cobalt magnet production?
Lead times can vary based on the complexity of the design, the specific grade of SmCo alloy used, the quantity ordered, and the manufacturer's production schedule. It's crucial to discuss and confirm lead times with your supplier during the planning stages.
Are there minimum order quantities for custom samarium cobalt magnets?
Yes, minimum order quantities may apply, depending on the manufacturer's policies and the specific requirements of the custom magnet, including its size, shape, and complexity.
