Star Trace as a leading magnetic equipment manufacturer has a good stock of Ferrite Magnet which has the composition of Iron oxide and barium or strontium carbonate. The Ferrite Magnets exhibit strong magnetic properties and resist demagnetization. They are available in an array of shapes and sizes to provide for the umpteen number of industries that make use of Ferrite Magnets.

The ferrite Magnets manufactured by us is highly appreciated by our customers for its accurate composition and efficient working. These magnets are formulated by using topnotch quality chemicals by our skilled professionals.

Features

• Inexpensive yet strong; a good balance between strength and affordability
• Does not demagnetize easily
• Can be magnetized with multiple poles if necessary.
• Do not rust

The only caution that has to be taken note of it that Ferrite Magnets are brittle though strong. Dropping them will shatter it into pieces. Our ferrite magnets are used in motors, magnetic couplings, for sensing, loudspeakers, crafts, therapy, novelties, and toys.

Ferrite Permanent Magnets:
Ferrite Permanent Magnets are Composed of Strontium carbonate and iron oxide. They are charcoal gray in color and usually appear in the forms of discs, rings, blocks, cylinders, and sometimes arcs for motors.

Manufacturing Ferrite Permanent Magnets:
A powdered mixture of strontium carbonate and iron oxide is injected into either a wet press or dry press for forming. During this pressing process, a magnetic field is applied in the direction of preferred magnetization to orient the material and increase the magnet's performance potential. This magnet is considered "oriented". If not exposed to a magnetic field at time of formation, it is called "non-oriented" (Isotropic).After the molding process, the material is then sintered at about 1010OC. This process is similar to that of kilting ferrite pottery, thus the popular name "Ferrit" magnet.Lastly, the magnet is finish-ground to size with a diamond-bladed grinding wheel, magnetized, and inspected for shipment.

Attributes Of Ferrite Permanent Magnets:
High intrinsic coercive force Tooling is expensive Least expensive material compared to alnico and rare earth magnetsLower service temperature than Alnico, greater than rare earth Finishing requires diamond cutting or grinding wheel Lower energy product than alnico and rare earth magnetsLimited to simple shapes due to manufacturing process Most common grades of ferrite are 1,5 and 8 (1-8 possible)Grade 8 is the strongest ferrite material available
