By optimizing the magnet’s composition, microstructure and surface treatment, our company has developed a series of low- weight- loss magnet , the weight loss of which can be lower than 1-5mg/cm² after the corrosion HAST test(130 ℃，2.7atm，100% humidity 7/14/20/30days), Our low weight loss of magnet reaches the current highest international standard.
