Sematic Magnet – Magnet Manufacturer

VIBRA® Samarian Cobalt Magnets

VIBRA® Samarian Cobalt Magnets

High-performance rare-earth magnets engineered to withstand temperatures up to 350°C with superior thermal stability and natural corrosion resistance for critical industrial use.

Why Choose VIBRA® Samarian Cobalt Magnets?

Designed to protect your equipment and ensure product purity in demanding industrial environments

Unmatched High-Temperature Performance

VIBRA® SmCo magnets are designed for extreme environments where standard magnets fail. With the ability to operate continuously at temperatures up to 3500°C, they maintain their magnetic strength and stability in high-heat motors, sensors, and aerospace applications without the risk of demagnetization.

Naturally Corrosion-Resistant

Unlike Neodymium magnets which require plating to prevent rust, our Samarian Cobalt magnets offer excellent intrinsic corrosion resistance. This makes them the ideal choice for medical, marine, and vacuum environments where surface coatings might flake off or fail.

Comprehensive Inventory & Shapes

Sematic Magnet specializes in a vast array of configurations to fit your exact project needs. Whether you require Discs, Countersunk Discs, Rectangular Blocks, Rods, Bars, Rings, or Pot Magnets, we supply precision-engineered shapes ready for immediate integration into your assemblies.

FAQs About VIBRA® Samarian Cobalt Magnets

What are the main benefits of VIBRA® Samarian Cobalt magnets?
High heat resistance and corrosion immunity. Withstands up to 350°C and resists oxidation without a protective coating, ideal for harsh environments.
SmCo handles heat better; Neodymium is stronger at room temp. SmCo is stable at high temperatures and non-corrosive; Neodymium is stronger but loses performance above 80°C–150°C and rusts easily.
No, generally not required. They are naturally resistant to corrosion due to low iron content, eliminating the need for standard nickel or zinc plating.
Discs, Rings, Rods, Bars, and Pot magnets. We stock a wide inventory, including Countersunk Discs and Rectangular magnets, and offer advice for specific geometries.
Yes, handle with care. The sintered structure means they can chip or crack easily from shock or forceful contact. Not suitable for structural use.
