This is sintered neodymium magnet, it is the third generation rare earth magnet.
It is the most powerful and strongest magnet in World at present.
We can provide the sintered neodymium magnet is teflon coating.
The magnet for teflon coating
This coating have many advantages:
1. First, wearable, good for anti-attrition.
2. Second, high working temperature, this coating can working under 380℃ temperature the highest.
3. Three, anti-rust, this coating have better protection for magnet rust than Ni, Zn and other coating.
The Ni or Zn coating magnet, the coating can be peeled under thick hydrochloric
acid, but for Teflon coating, it will not peel under any circumstance, except by physics
destroy(such as by sandblast).
4. Fourth, This coating costs not expensive, only a little higher than Ni coating.
In one word, it can used in very badly circumstance with a long time life and can save much more costs.
