Round Ferrite Disc Magnets

Açıklama

Round ferrite disc magnets are solid circular magnetic components without a central bore. They suit projects that need a flat circular footprint and can accommodate the selected ferrite grade and thickness.

Choose the disc from the application geometry and magnetic requirement. The diameter alone does not determine holding force, especially when a coating, fabric layer or air gap separates the magnet from its target.

Solid ceramic discs for compact assemblies

Provide the disc diameter, thickness, magnetization direction and mating material. For an adhesive-mounted assembly, show the available bonding face and the surrounding pocket clearance. Confirm the adhesive and preparation method through an assembly trial.

Inspect samples for chipped edges, dimensional fit and the behavior of the complete assembly. Ferrite should not be drilled or cut casually during installation. If a hole is essential, review a ring design before finalizing the part rather than trying to modify a finished disc.

Drawing-led specification and customization

Send a drawing with dimensions, tolerances, magnetization direction and the required quantity. Describe the working gap, mating material, mounting method and environment. These inputs help distinguish a suitable magnetic component from a part that merely fits the space.

Confirm the material grade and any surface treatment on the quotation. Do not infer a temperature rating, pull force or coating performance from the photograph. Where a measured requirement matters, agree the test arrangement and acceptance criteria before sample approval.

Handling and sample validation

Protect magnets from impact and from uncontrolled contact with other magnets or metal parts. Support brittle edges during assembly, keep loose pieces away from children and use appropriate precautions around magnet-sensitive equipment.

The sample review should cover dimensions, pole orientation, visible damage and function in the intended assembly. Record the approved specification and test setup so later comparisons use the same gap, mating material and orientation. Ask Richarms to confirm drawing feasibility and the sample process before scheduling production.

Questions about round ferrite disc magnets

Is a ferrite disc the same as a neodymium disc?

No. They are different magnetic materials. Compare the complete assembly requirement rather than substituting equal dimensions.

Can I add a hole after delivery?

Specify a ring or another prepared geometry when a hole is needed. Secondary work on brittle magnets requires a suitable process.

Can a photograph establish magnetic strength?

No. A meaningful strength requirement needs a defined measurement method, geometry and operating gap.

What is needed before a custom quotation?

Provide the dimensioned drawing, grade or functional requirement, magnetization direction, mounting environment and order quantity.
