Fine Pure Iron Powder (≥99.8% Purity)

Redefining Precision: What Makes Fine Pure Iron Powder Exceptional?

Fine pure iron powder (≥99.8% Fe) is a specialized metallic powder with particle sizes typically ranging from 1 μm to 40 μm, engineered for applications demanding extreme chemical purity and microstructural homogeneity. Unlike conventional iron powders, this material undergoes advanced refining processes-including hydrogen reduction, water atomization, or carbonyl decomposition-to achieve total impurity levels below 0.1%. Key contaminants like carbon (≤0.003%), sulfur (≤0.005%), and oxygen (≤0.12%) are minimized to near-atomic thresholds.

Technical Insights: How It's Made

Our iron powder is manufactured through gas atomization, a process that involves melting high-purity iron and injecting it with inert gas (e.g., nitrogen or argon) to produce spherical particles.

Low oxygen content (<0.1%) to prevent oxidation during storage or processing.

High compressibility (6.5–7.2 g/cm³) for superior green strength in powder metallurgy.

For applications requiring even finer particles, we offer carbonyl iron powder (CIP), produced via thermal decomposition of iron pentacarbonyl, yielding spherical particles with diameters as low as 50 nm.

Storage & Handling Recommendations

Store in a cool, dry environment (<30°C, <40% RH) to prevent moisture absorption and oxidation.

Use inert gas purging for long-term storage of bulk quantities.

Avoid contact with oxidizing agents or acidic environments.

Competitive Edge: Why Our Fine Pure Iron Powder Outperforms

FAQs: Critical Technical Insights

Q: Can this powder be used for metal injection molding (MIM)?

A: Absolutely-our spherical 5–25 μm powders achieve >96% density after sintering with 0.3% linear shrinkage. Use binder systems optimized for low oxygen (<200 ppm).

Q: How does particle size affect EMI shielding?

A: Smaller particles (1–10 μm) provide 30% better GHz absorption due to higher domain wall density. For 1–3 GHz range, use 15–25 μm blends.

Q: Is inert gas required for storage?

A: For carbonyl grades (O₂ ≤0.05%), nitrogen suffices. Water-atomized powders (O₂ ≤0.12%) require argon to prevent surface oxidation.
