Unlock the Potential of Elemental Excellence
1. Purity (Minimum 99.5% Fe)
Our pure iron powder undergoes rigorous refining to minimize contaminants like carbon (C), sulfur (S), phosphorus (P), oxygen (O), nitrogen (N), and trace metals.
Why it matters: High purity prevents unwanted chemical reactions (e.g., excessive oxidation), ensures consistent behavior during sintering or melting, guarantees reliable magnetic properties, and avoids weakening final products-critical for sensitive applications like magnetic components or chemical processes.
2. Particle Size Distribution (Customizable: -100 Mesh, -325 Mesh, etc.)
We offer standard and tailored particle sizes, specified by the percentage passing through mesh screens (e.g., 90% min. -325 mesh means 90% of particles are <44 microns).
Why it matters: Particle size directly impacts flowability, packing density, surface area, and sintering efficiency. Fine powders (e.g., -325 mesh) boost surface area for reactions but are harder to handle; coarser powders (e.g., -100 mesh) flow better and compact easily-ideal for automated production.
3. Apparent Density (2.5 – 3.5 g/cm³ Typical)
Measures how densely powder packs under non-pressing conditions.
Why it matters: Critical for powder metallurgy (PM) and metal injection molding (MIM). Consistent apparent density ensures uniform die filling, leading to consistent part weight and dimensions after compaction and sintering.
4. Flow Rate (e.g., <35 sec/50g)
Measures the time for 50g of powder to flow through a standard funnel.
Why it matters: Essential for automated PM/MIM lines. Good flow ensures fast, uniform die filling, reducing defects and maximizing production efficiency.
5. Chemical Composition (Beyond Purity)
Tight control over residual elements ensures performance:
Carbon (C): <0.03% – Excess forms brittle carbides, harming magnetic properties.
Oxygen (O): <0.3% – Low oxygen prevents oxides that weaken sintering, density, and corrosion resistance (vital for high-performance magnets).
Sulfur (S) & Phosphorus (P): <0.03% each – These elements embrittle iron, reducing ductility.
Nitrogen (N): <0.03% – Minimizes nitrides that disrupt mechanical properties.
Acid insolubles: <0.2% – Reduces inert impurities (e.g., silica) that weaken parts.
6. Physical Form
Particles are typically irregular (for strong compaction and sintering) or spherical (on request, for superior flow). Our powder is "reduced" (low oxygen/surface activity) to minimize oxidation during storage.

2. Electronics & Magnetics
Use: Core material for soft magnetic composites (SMCs).
Result: Efficient high-frequency motors, transformers, and EMI shielding.
3. Chemical Processing
Use: Reducing agent for wastewater treatment (e.g., removing hexavalent chromium) and fertilizer synthesis.
Result: Purified effluents, high-yield chemical reactions.
4. Pyrotechnics & Welding
Use: Fuel in sparklers/thermite; additive in welding electrodes.
Result: Combats iron deficiency anemia in populations.
FAQ
Q: What is Foreign Trade-Express?
A: Foreign Trade Express is a one-stop intelligent foreign trade network marketing SaaS system platform.
Q: Q: Reduced vs. atomized iron powder-what's the difference?
A: A: Reduced powder (from iron oxide reduction) has irregular particles (good compaction); atomized powder (molten iron broken into droplets) is spherical (superior flow). We offer both.
Q: Q: Can it make strong structural parts?
A: A: Pure iron parts have moderate strength/ductility. For high strength, mix with alloying elements (Cu, Ni, Mo).
Q: Q: Is pure iron powder magnetic?
A: A: Yes-strongly ferromagnetic, making it key for SMCs.
Q: Q: How to prevent rusting?
A: A: Seal containers tightly; store in dry areas. Use desiccants or inert gas for long-term storage.
Package
Pure iron is typically packaged with rust-preventive oil, wrapped in plastic film, and secured with plastic or metal straps. It is then placed on wooden pallets or in wooden crates, sometimes using moisture-proof paper or vacuum packaging for extra protection during transportation and storage.
