Ultra High Purity Iron (5N–6N Grade) Supplier
Ultra High Purity Iron (5N–6N grade, Fe ≥ 99.999%–99.9999%) represents the highest level of iron purity currently achievable in industrial supply. Compared with industrial pure iron (2N–3N) and high-purity iron (4N), ultra pure iron offers extremely low impurity levels (≤10 ppm for 5N, ≤1 ppm for 6N), ultra-low gas content, and unparalleled chemical stability.
Huaxiao-Alloy supplies 5N and 6N ultra pure iron in multiple forms—ingots, foils, granules, powders, wires, rods, and sputtering targets—to meet the demanding requirements of semiconductors, PVD coating, nanotechnology, and advanced research laboratories.

5. Why Choose Huaxiao-Alloy Ultra Pure Iron?
Purity guaranteed – 5N–6N iron with ppm/sub-ppm impurity levels
Custom solutions – ingots, foils, targets, powders, and wires
ISO-certified supply chain – reliable quality and global traceability
Cleanroom packaging – vacuum sealing and inert-gas protection
Technical expertise – supporting R&D, semiconductor, and aerospace sectors
5N iron has Fe ≥ 99.999% (impurities ≤10 ppm), while 6N iron reaches Fe ≥ 99.9999% (impurities ≤1 ppm). 6N is typically used in semiconductor and nanotechnology applications where ultra-trace purity is essential.
4N (99.99%) iron is sufficient for most electronic and magnetic parts. 5N–6N iron is required when impurity levels must be nearly eliminated—such as in thin-film deposition, semiconductor manufacturing, or high-level R&D.
Yes. Huaxiao-Alloy provides ultra pure iron sputtering targets with Fe ≥ 99.999% or 99.9999%, available in planar or rotatable designs, with cleanroom packaging and full COA.
Purity is verified through ICP-MS/ICP-OES analysis for metallic elements and LECO inert-gas fusion for O/N/H content. Third-party certification is available upon request.
We provide vacuum-sealed, inert-gas-filled packaging with cleanroom handling to prevent contamination.
