Performance 18-12*1mm Ring Neodymium Magnet
Product Description
Neodymium magnet (also known as NdFeB, or Neomagnet), a type of rare-earth magnet ,
is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal
crystalline structure. This material is currently the strongest known type of permanent magnet.
We could produce the neodymium magnet with teflon coating
The characteristic of teflon coating:
1. 0.08mm-0.1mm
2. SST (Salt Spray Test) 120 hours
3. Environmental, it could work in the application which had requirement to the water quality
4. Wearable, good for anti-attrition.
5. High working temperature, this coating could work under 380°C temperature highest.
6. It could work in acid circumstance or alkaline circumstance
As a manufacturer, we can provide goods directly without the intermediate links, so the price is 5%-15% lower than the average.
Latest technologies and equipments were adopted and upgraded continously ,also reduce production cost to ensure low price!
