This round base magnet, or cup magnet, is made of grade 8 ceramic magnet encased and embedded inside of a steel cup. The steel cup is chrome plated for rust proof. The magnet and the steel cup form a magnetic circuit so the holding force is quadruped to 100 LBS with direct touch to a 3/4" thick low carbon steel plate. The steel cup also provides protection to the magnet so it becomes much more durable, allowing for use in more demanding applications.
The outer diameter of the magnet is 3.2" (80 mm) with 0.27" (6.5 mm) center hole (for a #8 bolt). The total thickness is 0.39" (10 mm).
This magnet can be used as magnetic holding, lifting, antenna mounting, positioning, retrieving and much more.
Round base magnets are also known as cup magnets.
The product quality is assured by ISO 9001 quality control systems.
- MAGNETIC STRENGTH (GRADE 8) - Chemical compound of permanent ferrite magnets is SrO-6 (Fe2O3), a combination of strontium carbonate and iron oxide. These type of ceramic magnets are graded on a scale of 1-8 with 8 providing the strongest magnetic applications.
- MAGNETIC APPLICATIONS - Ceramic magnets are used in magnetic assemblies designed for lifting, holding, retrieving, and separating. Good for tool racks, cabinet fixture, magnetic car mounting, fishing, and other creative use.
- AS COMPARED TO NEODYMIUM - Good balance of magnetic strength, resistance to demagnetization, anti-corrosive properties, and economical. However, ferrite is much more brittle to use especially on direct contact with another heavy object when attracted.
- PULL FORCE - Listed pull force results are lab tested for industry standards against a steel plate in horizontal position. Actual performance may vary depending on the variables like friction, gravity, lubrication, and surface. For horizontal applications, the performance will be close to the listed pull force. For vertical placement, performance may vary 15-30% of the listed pull force.
- WARNING: Magnetics are strong and may pinch your fingers when have two more magnets close together. Keep away from children, supervision is advised. Keep magnets away from pacemakers. Ceramic magnets are brittle and may crack or fragment into pieces when colliding with another object with great force.
