How does the addition of Terbium Metal improve the performance of NdFeB magnets?
Integrating this metal into NdFeB formulations significantly increases the intrinsic coercivity of the magnets. This means the end product can operate effectively at much higher temperatures without losing its magnetic properties, which is critical for electric vehicle motors and wind turbines.
What specific precautions should our facility take when handling and storing this material?
While corrosion is extremely slow at room temperature, the metal should be kept in its original argon-filled, vacuum-sealed packaging until immediately before use. Store the iron drums in a cool, dry, and well-ventilated warehouse, away from strong acids and oxidizing agents.
Can you customize the physical dimensions of the ingots to fit our specific vacuum induction melting furnaces?
Yes, we specialize in physical form customization. Our engineering team can cut and shape the standard lumps or ingots to match the exact crucible dimensions of your melting equipment, thereby reducing your preparation time and optimizing the melt rate.
What is the difference between the Vacuum Distillation and Metallothermic Reduction preparation methods you offer?
Metallothermic reduction is highly effective for producing the base metal with excellent structural integrity. Vacuum distillation is a subsequent, advanced purification step that vaporizes and removes trace volatile impurities, achieving the ultra-high 3N and 4N purity grades required for sensitive electronic and optical applications.
How do you verify the purity levels, and what documentation is provided with our shipment?
We utilize advanced analytical techniques such as Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to accurately quantify rare earth and non-rare earth impurities down to the parts-per-million level. Every shipment includes a comprehensive Certificate of Analysis (COA), and we can provide independent third-party lab reports upon request to ensure absolute compliance with your specifications.
