CMS MAGNETICS - 5-Pack RB60 C8 Ceramic Ferrite Round Base Magnet with Anti-Corrosion Chrome Plated Steel Cup and 50 LB Pull Force - Cup Diameter: 60.4mm, Center Hole: 6.9mm, Thickness: 8.9mm

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.
This listing includes five cup magnets made of grade 8 ceramic magnet encased inside of a steel cup. The steel cup is chrome plated with a shiny finish. The magnet and the steel cup form a magnetic circuit which triples the holding power to 50 LB direct pull on a solid steel surface. The steel cup also provides protection to the magnet so it becomes much more durable. The outer diameter of the magnet is 2.4" (60 mm) with 0.27" (6.5 mm) center hole (for a ¼" screw). The total thickness is 0.35" (8 mm). This magnet can be used for magnetic holding lifting antenna mounting positioning retrieving and much more. Cup magnets are also known as round base magnets sometimes. The product quality is assured by ISO 9001 quality control systems.Not the magnets you played with as children 15-20 times the force of those old time magnets.
