Industrial Customized Neodymium Ring Magnets
1.High corrosion resistance and low weight loss products
There are two main standards of low weight loss test as follows:
1). USA PCT: 121±1℃, 2 atm, 95% RH, 96 hours, weight loss less than 5~10mg/cm2
2). Europe HAST: 130±2℃, 3 atm, 95% RH, 168 hours, weight loss less than 2~5mg/cm2
Due to special material formulation and manufacturing process, the corrosion resistance is so excellent that magnets can reach the strict testing requirements above. These magnets are widely used in elevator, wind generator, military and aerospace industries.

Neodymium is a metal which is ferromagnetic (more specifically it shows antiferromagnetic properties), meaning that like iron it can be magnetized to become a magnet, but its Curie temperature (the temperature above which its ferromagnetism disappears) is 19 K (−254 °C), so in pure form its magnetism only appears at extremely low temperatures. However, compounds of neodymium with transition metals such as iron can have Curie temperatures well above room temperature, and these are used to make neodymium magnets.
