Also known as ceramic magnets, ferrite magnets offer excellent value for money when pull strength is not the most important factor. They have a high resistance to corrosion and demagnetisation, can operate in temperatures up to 180C and are commonly used in conveyor systems, switches and manufacturing. VERSATILE MAGNET FOR SEVERAL APPLICATIONS. Commonly used in Conveyor Systems, Switches, Speakers, Arts, Crafts, Science, and DIY. HIGH OPERATING TEMPERATURE. Can operate in temperatures up to 180 degrees Celsius. RESISTANT TO DEMAGNETISATION. Excellent resistance to demagnetisation. RESISTANT TO CORROSION. They have a high resistance to corrosion without any extra coating. STRONG RARE EARTH MAGNET. 4.5kg maximum pull from the magnetic surface when in flush contact with a mild steel surface of equal thickness to the magnet. SPECIFICATIONS. 75mm x 50mm x 10mm. Each magnet's north and south poles are on opposite 75mm x 50mm rectangular faces.
