FAQ
Q1. How does NdFeB material composition influence corrosion resistance?
Answer:Grain boundary chemistry and rare earth content affect corrosion pathways. Certain compositions require more robust coating systems to achieve equivalent durability.
Q2. What limits achievable tolerances in sintered NdFeB magnets?
Answer:Material brittleness, sintering shrinkage variability, and grinding limitations set practical tolerance limits. Extremely tight tolerances require increased machining and inspection cost.
Q3. How does magnetic shielding in packaging prevent performance loss?
Answer:Shielding reduces stray fields that could attract external metal or interact with other magnets, preventing mechanical damage and unintended partial demagnetization during transport.
