Eclipse Magnetics Alnico Rectangular Bar Magnets are durable permanent magnets designed for technical, industrial, laboratory and educational applications where a clearly defined magnetic axis and stable magnetic performance are required.
Manufactured from high-quality Alnico 2 or Alnico 5 material, each rectangular magnet is precision-ground for consistent dimensions and magnetic strength. The magnetic poles are clearly identified by a notch or dimple, helping with correct orientation during installation, testing and experimental work.
The range includes five variants with lengths from 20mm to 75mm and magnetic field strengths of either 750 or 1100 Gauss. The Alnico 2 models provide 750 Gauss, while the Alnico 5 versions provide a stronger 1100 Gauss field.
Supplied in matched pairs, these rectangular bar magnets provide consistent magnetic characteristics and are suitable for applications including sensors, relays, magnetic filtration systems, laboratory equipment, educational demonstrations and general engineering use.
With operating capability up to 550°C, these magnets are particularly well suited to applications where dependable magnetic performance is required at elevated temperatures.
