This is an ultra-thin circular magnet made of rare earth ndFeb.Rare earth Ndfeb is the most powerful permanent magnet in commercial use, and it is also relatively cost-effective. The magnet is 4mm in diameter and only 0.5mm thick. Ultra-thin round magnet we generally choose thickness magnetization, the surface coating color is silver white, it used nickel - copper - nickel three layer plating, but Epoxy,Zinc,Gold,etc coatings are available to choose.

The other thickness of 4mm magnet:

4mm diameter x 1mm thick

4mm diameter x 1.5mm thick

4mm diameter x 2mm thick

4mm diameter x 3mm thick

4mm diameter x 4mm thick

4mm diameter x 6mm thick

4mm diameter x 8mm thick

4mm diameter x 10mm thick

The appilication of 4mm x 0.5mm neodymium round magnet:

It is widely used in CDDVD-ROM, generator, motor, servo motor, microphone, alarm, stage sound, permanent magnet mechanism vacuum circuit breaker, nuclear magnetic resonance instrument, medical instruments, magnetic health care products, toys, automatic mahjong machine, magnetic locks, doors and windows magnetic, stationery magnetic, etc.

We not only have these size, our torelance is 0.05mm, you can contact us and provide your requiry of magnet, we will made the sample for you.
