Ferrite, Flexible Rubber or Neodymium: Choosing a Fridge Magnet Backing
The metal front gets the attention, but the magnet on the back decides whether the piece stays on the fridge. For custom metal fridge magnets you can choose ferrite, flexible rubber or neodymium backing. This guide explains how each one is used and what to confirm before production.
The three backings at a glance
| Backing | What it is | Often chosen for |
|---|---|---|
| Ferrite | A rigid ceramic magnet, usually a disc or block on the back | Everyday souvenir and promotional magnets |
| Flexible rubber | A thin magnetic sheet cut to the outline or to part of the back | Flat designs where a low profile matters |
| Neodymium | A small, strong rare-earth magnet | Heavier or thicker metal pieces, or backs with only a small flat area |
How well a magnet holds depends on the magnet size, the weight of the metal part and the surface it sits on, so we confirm the backing on the physical sample instead of quoting a pull figure.
Start from the metal part
A thick 3D zinc-alloy magnet is heavier than a flat 2D piece of the same size. The rear construction must leave enough flat area for secure magnet attachment, and any rear marks have to fit around it. Send the size and thickness you have in mind and we suggest a backing on the proof.
Plan the back together with the front
- Where the magnet sits and how large it is
- Whether the back has a recess for the magnet
- Any logo, text or barcode you want on the back
- Whether the piece will hang on a fridge, a whiteboard or another steel surface
Check it on the sample
The physical sample takes 10–14 working days, plus 7 working days if we create the design. It shows the finished weight, the backing and how the piece holds on a steel surface. Approve the backing together with the front before mass production, which takes 30–60 days depending on quantity and finish.
Packing for retail
Retail projects may add a backing card, barcode and protective pack. Strong neodymium magnets should be packed so pieces cannot snap together and mark plated or painted surfaces.

FAQ
Which magnet backings can I choose?
+
Ferrite, flexible rubber or neodymium. Tell us your preference or ask us to suggest one for your design.
Can you tell me the pull strength?
+
We confirm the hold on the physical sample with your actual metal part, because its size, weight and the surface all affect it.
What is the minimum order?
+
From 100 pcs per design. Unit price drops significantly at 500 pcs and again at 1,000+ pcs.
