Overview - Ferrite (Ceramic) Disc Magnets

Ferrite, (also known as  Ceramic)  disc magnets are round coin-shaped ceramic ferrite magnets of varying diameter and thickness. They are almost always manufactured as axially magnetised ceramic ferrite magnets.

Our ferrite disc magnets would be supplied as axially magnetised ferrite disc magnets unless we state otherwise. They  have been magnetised along the central axis so the poles are at either end of the disc (a North on one side; a South on the other side).

Ferrite disc magnets can be stacked on top of each other to create taller magnets which can offer more potential performance. As the ferrite discs height increases the performance will also increase until extra height starts to give less benefit per magnet addition. Eventually the performance plateaus off as the height increases, at which point a larger diameter disc magnet may be needed if more performance is required.

Starting with thinner magnets then increasing height is a good test method when you are unsure what performance and/or magnet size you require. Ferrite disc magnets can be glued in place as required. They do not like being press fitted - too more compaction force risks breaking, chipping or shattering the magnets. The ceramic ferrite disc magnets give more pull force when attracting another magnet than when attracting a ferromagnetic (e.g. mild steel) part.

Unplated Ferrite Disc Magnets

The ferrite disc magnets are unplated as standard. It is possible to plate the ferrite disc magnets and to produce custom magnet shapes and even diametrically magnetised ferrite disc magnets upon request. We can also produce alternative grades of ferrite upon request - we supply custom magnets.

"We were delighted with the service provided by Eclipse Magnetics; from the initial site survey through to delivery."

Adrian Seeley, Production Supervisor at AB MAURI UK & Ireland

"I cannot begin to tell you how much it has helped our operation, the magnetic filtration unit has been a real problem solver it has surpassed all our expectations. Its cured a 30 year plague!"

Maintenance Manager at EXL Tube (Steel Ventures)

"This technology is economical, reliable and efficient. I believe that magnetic filtration technology is the future."

John Smith, MMTCI

"Magnetic filtration has dramatically cleaned up our fluids and improved the surface finish we can offer. It extracts around 50Kg per day of ferrous waste."

Facilities Manager, Milacron Machines (Sub-Contract Machining)

"We chose Eclipse Magnetics to supply our housed grid because they are a respected and well-established brand. They offered us a very competitive price, and the process of ordering and installation was straightforward and reliable."

Pat Richards, Chief Engineer at Simpsons Malt

“We are delighted with the Automag installation; it’s solved all the problems we were having previously with downtime and maintenance costs. The filter means that we are able to use recycled water, which is saving us £1000 per week!”

Kenneth McRae, Principle Engineer at Vallourec

"Here at Qualflow, we base our business on a philosophy of make the product simple to use, reliable and cost-effective. Eclipse Magnetics’ neodymium magnets offer the strongest magnetic performance, and are nickel plated, making them a cost effective.."

Justin Lawler Ph.D. MBA, Chief Technology Officer at Qualflow Systems Ltd

"The Ultralift Plus magnetic lifter from Eclipse Magnetics is the perfect solution for the pick-up and transportation of the ultrasonic calibration blocks in our facility"

John Crossley, NDT Technology Lead at the Nuclear AMRC

"The result is an aesthetically pleasing system, which is effective in trapping metal contaminants and is easy to clean..."
