1. Working temperature for Neodymium ring magnets:from 80 centigrades to 200 centigrades.

2. Coatings: Ni, Zn, epoxy, gold, silver, Cu and so on(as per the requirements).

3. Can be magnetized according to the requirements of clients, thickness, diameter, muti-poles...

4. With precise tolerance.

5. Neodymium magnet has super strong magnetic force and high intrinsic coercive force.

Pros: Very strong hold when contacting another magnet or plain iron, very difficult to pull away (easy to slide however).Pretty strong hold between two of these even with a couple of mm in between.

Cons: Would like thicker (and more powerful) versions. Sure u can stack these together but sometimes it's not the same thing.

Other Thoughts: Good for attaching thick stacks of paper to refrigerators etc or pinching together papers or textiles.
