## Description

From the manufacturer Alnico magnets have been in production since the early 1930’s and are the most recognised form of magnet. They are strong, typically less brittle than most rare-earth magnets and can be magnetised to produce a strong magnetic field. While Alnico is not as strong as rare earth, they are still commonly used in the manufacturing of sensors, guitar pickups, loudspeakers and many other everyday household objects. Widely used in manufacturing and engineering industries for their strength and depth of magnetic field, horseshoe magnets are often used to solve many problems that would otherwise require a very costly solution.

## Features

- IDEAL FOR ENGINEERING & MANUFACTURING. This magnet is popular in engineering and manufacturing industries due to its strength, operating temperature, and corrosion resistance properties.
- RESISTANT TO CORROSION. Resistant to corrosion with a 500-degree Celsius operating temperature makes this magnet ideal for high-temperature and underwater/sub-sea applications.
- PROTECTIVE COATING. Protective epoxy coating.
- SPECIFICATIONS. 30mm x 20mm x 20mm. 20mm x 7.3mm individual pole faces. 4.5mm hole. 4.5kg pull.
