Advantages of Samarium Cobalt Magnets

Temperature stability
The defining characteristic of samarium cobalt magnets is their exceptional temperature stability. These magnets can operate at higher temperatures compared to other types of magnets, without significant loss of magnetic strength.

 


Corrosion resistance
Samarium cobalt magnets are known for their resistance to corrosion, which enhances their durability and longevity. This corrosion resistance means samarium cobalt magnets do not need to be plated to protect them, unlike neodymium iron boron.

High magnetic strength

Samarium cobalt magnets exhibit extremely high magnetic strength, surpassing many other types of permanent magnets. This characteristic makes them ideal for applications where a strong and stable magnetic field is crucial, such as in sensors, magnetic couplings, and certain types of motors.

Low temperature coefficient

Smco magnets have a low-temperature coefficient of magnetic remanence and coercivity. This means that their magnetic properties are less sensitive to temperature changes compared to other magnet materials.

Long operational life

The robustness and stability of samarium cobalt magnets contribute to their long operational life. Their resistance to demagnetization, corrosion, and temperature variations ensures that they can maintain their magnetic properties over an extended period.

 

Applications of Samarium Cobalt Magnets

 

Sensors

Samarium cobalt magnets are used in sensors. These sensors are concerned with converting a magnetic field into electrical signals. The sensors are usually used in aerospace and automobiles.

01

Generators

Samarium cobalt magnets are used in generators. The samarium cobalt magnet provides the magnetic field for the generator. These generators are reliable and can be used in wind turbines.

02

Refrigerators

Samarium cobalt magnets are fast becoming popular in the refrigeration industry. Massachusetts Institute of Technology is currently researching how magnets can be used as refrigerants.

03

Nuclear Magnetic Resonance Spectrometer

Samarium cobalt magnets are also used in NMR spectrometers. In NMR spectrometers, magnets are used to investigate the spin of protons and neutrons. NMR spectrometers are used to study both the physical and chemical properties of organic compounds.

04

Medicine

Samarium cobalt magnets are used in medical equipment that require high temperatures for sterilization. This is because samarium cobalt magnets are stable under high temperatures. They are also used for medical implants.

Samarium Cobalt Magnets Features & Characteristics
 
01/

Rades & materials
We carry a large inventory of licensed, samarium cobalt magnet materials in standard and premium grades for reduced production and lead times. We offer sintered smco magnets in grades that range from 16 mgoe to 33 mgoe.

02/

Sizes & shapes
Standard samarium cobalt magnet shapes include discs, blocks, rings, and arc segments in a variety of sizes and grades. Non-standard shapes can also be custom fabricated to blueprint specifications from raw stock.

03/

Temperature considerations
Samarium cobalt magnets exhibit magnetic properties that are very stable with temperature, and can be used in applications where temperatures reach up to 572°f (300°c). They perform well for applications where the stability of magnetic characteristics is critical.

04/

Manufacturing methods
Samarium cobalt magnets are extremely brittle, so they are prone to chipping and cracking. Therefore, special machining techniques involving diamond-grinding must be used to machine this material prior to magnetization. We are fully equipped to machine these materials to your project’s specialty requirements.

05/

Surface treatments
The corrosion resistance of samarium cobalt is very good, therefore coatings to prevent corrosion or oxidation are generally not required.

06/

Magnetizing & assembly considerations
Smco magnets are anisotropic, and can only be magnetized in the orientation direction. Magnetizing fields in excess of 50 koe are required to saturate these materials.

We Recommend the Following Treatments for Samarium Cobalt Magnets

SmCo Magnets are very strong and brittle, requiring appropriate handling and packing to ensure safety and prevent damage. Most receiving departments are not familiar with the strength of Samarium Cobalt magnets and this can result in injury or broken parts. All personnel that may come in contact with this alloy should be made aware of the dangers of handling these magnets. The brittle nature of the alloy can lead to flying chips if the magnets are allowed to impact each other or a solid surface. Larger magnets can become a pinching hazard if caution is not exercised. We urge all customers to discuss handling techniques pertinent to their magnets with a our team member.

FAQ
 

 

Q: How many types of samarium cobalt magnets are there?

A: There are two types: Smco5 (1:5 type) and sm2co17 (2:17 type), each with distinct composition and performance characteristics.

Q: What is the main difference between smco5 and sm2co17?

A: Smco5 typically has higher magnetic strength, while sm2co17 offers better temperature stability and corrosion resistance, suitable for harsher environments.

Q: How do smco5 and sm2co17 differ in magnetic performance?

A: Smco5 has higher magnetic strength, with energy product ranging from 16-25 mgoe, while sm2co17 can reach up to 20-35 mgoe and is better for high-temperature applications.

Q: How strong are SmCo magnets?

A: SmCo magnets have high magnetic strength, though not as high as the strongest neodymium magnets. Their strength is sufficient for most applications where temperature stability and corrosion resistance are also important factors.

Q: Do SmCo magnets need a protective coating?

A: Generally, SmCo magnets do not require a protective coating due to their inherent corrosion resistance. However, for specific applications or environments, a coating might be applied for additional protection or for aesthetic reasons.

Q: How do I choose between a smco and a neodymium magnet for my application?

A: The choice between smco and neodymium magnets depends on several factors, including the required magnetic strength, temperature conditions, exposure to corrosive elements, and budget constraints.

Q: How should custom samarium cobalt magnets be handled and stored?

A: 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.

Q: What are the lead times for custom samarium cobalt magnet production?

A: 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.

Q: How do I choose the right grade of samarium cobalt magnet?

A: 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
