You are here]() ## Browse magnetic alloy systems Start with NdFeB or SmCo, then the grade and powder process. ### Bonded NdFeB powder directions Choose isotropic or anisotropic powder according to the intended bonded-magnet process. For an anisotropic request, include the alignment process and the conditions used for magnetic evaluation. #### Isotropic bonded NdFeB magnetic powder Magnetic grade, particle distribution, passivation and bonded process. [Ask about this material]() Nd-Fe-B alloy; grade-specific composition #### Anisotropic bonded NdFeB magnetic powder Alignment and bonded process, particle profile and magnetic test basis. [Ask about this material]() Nd-Fe-B alloy; grade-specific composition ### Samarium-cobalt alloy families Keep the 1:5 and 2:17 alloy families distinct. SmCo5 is a nominal identity; the 2:17 family can include Fe, Cu and Zr. Compare the actual grade composition, particle profile and magnetic acceptance method. #### SmCo5-type alloy powder Actual alloy composition, powder form and magnetic acceptance method. [Ask about this material]() SmCo5 nominal; actual grade to confirm #### 2:17-type samarium cobalt alloy powder Actual composition, powder route, particle profile and magnetic test basis. [Ask about this material]() Sm2(Co,Fe,Cu,Zr)17 family; grade-specific ## Questions before sampling **What should I send for an NdFeB powder inquiry?** Include the magnetic grade or reference datasheet, isotropic or anisotropic requirement, particle distribution, passivation and bonded-forming process. Any magnetic figures need the specimen and test conditions. **How do I specify a samarium-cobalt powder?** Start with the 1:5 or 2:17 family, then the actual grade composition and required powder form. Include the particle profile and magnetic acceptance method used by your process. ## What to include in your request A material name or reference datasheet is enough to start. Add any requirements you already know. - NdFeB or SmCo grade and composition basis - Isotropic or anisotropic powder requirement - Particle profile, supplied surface state and process - Magnetic test conditions, quantity and documents ### Quantity, samples and documents Nike has no fixed minimum order. Tell us the quantity you need; we’ll check supplier pack sizes and any minimums. We’ll check the proposed grade, sample options, delivery timing and available batch documents. Include any essential COA, TDS or SDS requirements.
