Formula: Nd₂Fe₁₄B
Form: Rod
Material: Neodymium/Iron/Boron
Commodity: Alloys
Type:
Rare Earth Magnet
Neodymium Iron Boron Alloy Rod (Nd₂Fe₁₄B) combines exceptional magnetic performance with robust mechanical strength, making it suitable for high-load magnetic assemblies and precision-engineered devices. Its composition supports high remanence and strong resistance to demagnetization, essential for stable long-term performance. Industries such as renewable energy, electric mobility, and aerospace employ these rods in applications requiring compact yet powerful magnetic sources. Specific uses include magnetic couplings in wind turbine generators, high-torque motors, and advanced propulsion systems. In research, they enable the study of magnetic field optimization, mechanical stress tolerance, and advanced motor designs. Their synergy of mechanical integrity and high magnetic output ensures lasting value in both innovation-driven projects and large-scale industrial deployment.
