NdFeB Rare Earth Super Magnets Governor Magnet Wear Resistant Rare Magnetic Metals
Our NdFeB magnets stand out in governor applications due to their exceptional features:
Smooth Coating and High Durability:
Our magnets feature an ultra-smooth coating that minimizes resistance, ensuring they are highly wear-resistant and can withstand high temperatures.
High Remanence and Strength:
With a significant remanence and superior strength, our magnets maintain their magnetic properties even at elevated operating temperatures, making them resistant to demagnetization.
Unmatched Cost-Effectiveness:
Among all magnet materials available, our NdFeB magnets offer the best value for money.
Our annual production capacity is 3,000 tons, and we have a strategic partnership with Chinalco, China’s leading rare earth miner. This partnership ensures a complete production chain and a robust quality assurance system.
