Sematic Magnet – Magnet Manufacturer

VIBRA® Alnico Magnets

VIBRA® Alnico Magnets

The ultimate choice for extreme heat environments. VIBRA® Alnico magnets offer superior temperature stability up to 500°C and excellent corrosion resistance for specialized industrial applications.

Why Choose VIBRA® Alnico Magnets?

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

Unmatched High-Temperature Performance

VIBRA® Alnico magnets are the industry leader for thermal stability, retaining their magnetic strength at temperatures up to 500°C. This makes them indispensable for sensors, high-temperature tooling, and electric motors where Neodymium or Ferrite magnets would permanently demagnetize.

Superior Durability & Corrosion Resistance

Composed of Aluminum, Nickel, and Cobalt, these magnets possess excellent natural resistance to oxidation. They do not require surface coating or plating, ensuring long-term reliability even when exposed to lubricants, solvents, or oil in harsh automotive and aerospace environments.

Extensive Shape Versatility

Sematic Magnet offers a vast inventory of classic and complex configurations, including Horseshoes, Bars, Rods, Channels, and Rotors. Whether you need Cast Alnico for higher energy or Sintered Alnico for precise mechanical strength, we provide the exact geometry your project demands.

FAQs About VIBRA® Alnico Magnets

What are VIBRA® Alnico magnets best used for?
They are used in high-heat sensors, meters, and sensitive instruments. Their stability ensures consistent performance in speedometers, guitar pickups, and aerospace sensors requiring precise magnetic fields.
They can operate effectively at temperatures up to 500°C. This is the highest operating temperature of any standard permanent magnet material available on the market today.
No, they have excellent natural resistance to rust and corrosion. The nickel content provides inherent protection, making them safe to use in oil, solvents, or humid air.
Cast allows complex shapes; Sintered offers better mechanical strength.Cast Alnico is generally stronger magnetically, while Sintered Alnico is preferred for small, intricate, and structurally stronger parts.
We stock Horseshoes, Rods, Bars, Discs, and U-channels. Sematic Magnet maintains a wide range of these traditional shapes, often used in educational and industrial settings.
