Isotropic vs Anisotropic Powder
The magnetic orientation of individual particles determines what you can do with the powder:
- ✓Isotropic — particles randomly oriented — magnets made from it can be magnetized in any direction; lower energy product (4–8 MGOe); the standard for most bonded applications
- ✓Anisotropic (HDDR) — particles crystallographically aligned — 1.5–2× stronger when magnetized along the alignment axis but requires field-oriented pressing or molding
- ✓Our recommendation — start with isotropic; move to anisotropic only if your application needs the extra performance and can tolerate the process constraints
Handling & Storage
Magnetic powders are reactive — handle and store properly:
- ✓Oxidation — reactivity depends on grade, size distribution and surface treatment; obtain the current safety data sheet and follow its specified handling controls rather than using a particle-size cutoff as a safety rule
- ✓Storage — use the supplier-specified atmosphere and sealed packaging; confirm the stated 6–12 month reference against the selected grade and storage conditions
- ✓Safety — wear respiratory protection — NdFeB dust is harmful if inhaled; consult our MSDS before handling
- ✓We can help — if you lack powder-handling infrastructure, we also supply finished bonded magnets from our own powder — one less thing to manage

Frequently Asked Questions
Can you supply powder or only finished magnets?
Both. Most of our powder production feeds our own bonded magnet lines, but we supply powder directly to qualified customers with appropriate handling capability. Tell us your application — we'll recommend whether powder supply or finished magnets better serve you.
What's the difference between melt-spun and HDDR powder?
Melt-spun (rapidly solidified) powder is isotropic — good for general bonded magnets. HDDR (hydrogenation-disproportionation-desorption-recombination) powder is anisotropic — 1.5–2× stronger but must be magnetized along its alignment axis. HDDR costs 30–50% more and requires field-orientation in your process.
Do you provide MSDS and safety documentation?
Yes — MSDS, transport classifications (UN and IATA where applicable), and handling guidelines accompany every powder shipment. NdFeB powder is classified as flammable solid for fine grades — we ship with appropriate declarations and packaging.
What particle size do I need for injection molding?
Injection molding requires fine powder (D50 5–20μm) to flow through nozzles and fill thin-wall molds without segregating from the polymer carrier. Coarser powder (D50 >50μm) works for compression bonding where the powder is mixed with minimal binder and pressed in a die.
