CMS MAGNETICS - 8-Pack RB36 C8 Ceramic Ferrite Features
-
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.
About CMS MAGNETICS - 8-Pack RB36 C8 Ceramic Ferrite
CMS MAGNETICS Round Base Cup Magnets (Pot Magnets) Magnet Material: Ceramic Ferrite (Fe2O3) Magnet Strength: Grade 8 (strongest of the ferrite type magnets) Cup Material: Chrome Plated Stainless Steel SPECIAL PROPERTIES: Advantages - Both the ferrite magnets and chrome plated stainless steel cups are resistant to corrosion, thus providing a long lasting solution for your applications as compared to the metallic neodymium magnets. - Magnet is stronger with the ferrite side facing outwards towards the object it will magnetically attract. Disadvantages - Magnet is weaker if installing the stainless steel cup side facing outwards but will better protect the ceramic ferrite inside. - Ferrite can be brittle and may chip if not careful when placing attracting heavy metal objects towards it. It is suggested that object placement should cover the outer protective steel cup perimeter PULL FORCE: Horizontal vs Vertical Placement Pull force is the force that’s required to pull a magnet away from a steel plate vertically, such as from the underside of a steel beam or table. If you aren’t using your magnet in a vertical application, but in a horizontal application, such as to the front of a refrigerator or filing cabinet, it will not hold its listed pull force. The magnetic force will pull the magnet straight towards the steel door as gravity tries to pull the magnet down to the floor. Friction between the magnet and door is what prevents it from sliding all the way down to the floor. This is referred to as shear force. It will have a much smaller maximum value, somewhere between 15 and 30% of the pull force, but is too difficult to predict as there are too many variables between the two materials and any lubrication there might be on the surfaces. APPLICATIONS: - Do-it-yourself (DYI) projects - Magnetic tool holder for tool rack organization - Cabinet holding base fixture - Retrieving objectives - Fishing - Treasure hunting - Car signs holding
