Introduction to Samarium Cobalt Magnets

Samarium cobalt magnets are primarily made from samarium, cobalt, and other metals. These materials are blended in specific ratios and undergo processes like high-temperature melting, powder making, pressing, and sintering to form various grades of blanks. Then, based on users' required properties, selected blanks are machined into desired shapes and finally magnetized.

Production Process

AMT's Product Advantages

We produce a series of sintered samarium cobalt products in various shapes and performance levels. Our advantages include:

• Maximum size for a square block is 130mm×130mm×100mm, achieving full magnetic saturation

• Mass production of high-grade YXG-33H samarium cobalt products with a (BH)max of 30-33MGOe

• Mass production of samarium cobalt products with HK≥18KOe, featuring high HK and stability

• Production of planar multi-pole samarium cobalt products with a magnetizing thickness limit of generally 6mm

• Mass production of 1:5 pure samarium cobalt products

• Mass production of large-size radially magnetized magnet components for magnetic levitation high-speed motors and magnetic levitation blowers

• Customization of samarium cobalt magnets to users' special performance requirements and continuous development of new grades

• Production of products where the deviation between the magnetizing direction and the mechanical axis is within 1° (for magnetized products)

• Customization of ultra-high magnetic energy product YXG-35 samarium cobalt products: Br reaches 11.6-12kGs, and (BH)max reaches 32-35MGOe

• Customization of ultra-low temperature coefficient LTC(YXG-18) samarium cobalt products: Under RT-100℃, the Br temperature coefficient is -0.001%/℃

• Customization of high-temperature resistant HT500 samarium cobalt products, which can operate up to 500℃

• Production of various complex-shaped and multi-angularly magnetized samarium cobalt magnet assemblies, such as Halbach arrays

Our Industry Leadership

Our customers are worldwide, and many large companies from various countries have adopted our products, which are widely used in aerospace, rail transportation, high-temperature motors, microwave devices, magnetic power transmission, etc. We welcome new and old customers to consult and cooperate!

Conventional Sizes and Shapes

Conventional size and shape: Conventional Sizes and Shapes Schematic.pdf

Among the three dimensions noted above, only one or two maximum dimensions can be produced. M represents the magnetizing direction. Due to the extreme brittleness of samarium cobalt materials, the thickness of products with large outer diameters or large square sizes can't be too thin. Also, the walls of large annular products can't be too thin. The above introduces conventional-shaped products. Our company can also produce samarium cobalt products in various other shapes. Feel free to inquire with drawings.

Special Splicing Process

When multiple direction dimensions are required to be large, our company's special splicing process can be adopted.

Thickness Considerations

Due to the extreme brittleness of samarium cobalt materials, the thickness of products with large outer diameters or large square sizes can't be too thin, and the walls of large annular products also can't be too thin. Specific requirements should be determined based on factors such as drawings, shapes, and magnetizing directions.

Notes for Inquiry

When inquiring about prices, please provide detailed information such as dimensions, tolerances, performance grades, quantities, whether electroplating is needed, magnetizing methods, and other special requirements. For non-standard products, drawings should also be provided.
