Magnet pentru pierderea în greutate
The corrosion resistance of Neodymium magnet is considered poor, surface coating is highly recommended for Neodymium magnets. With the expansion of elevators, wind turbines and permanent motors application, the users need higher requirement on corrosion resistance of Neodymium magnet, as the glue cohesiveness of unplated magnet is much better than plated magnets, also unplated products are better in the security.
Now, more and more customers tend to use unplated magnets, upon this condition we have developed ultralow weight loss magnets after the continuous innovation and study. Normally, the weight loss test is over 150mg/cm² in the industry of Neodymium magnet, this will be different for magnets produced from different material formulation and manufacturing process.
A lot of our new magnets can reach to 1mg/cm², (Testing condition HAST standard for 168hrs), due to its very low weight loss, the corrosion resistance is excellent
US Standard:PCT (121℃±1℃), 2 atm, 95%RH, for 96 hours, weight loss less than 5-10mg/cm2
EU Standard:HAST (130℃±2℃), 3 atm, 95%RH, for 168 hours, weight loss less than 2-5mg/cm2
