Medium-temperature phosphating achieves membrane layer quality similar to that of high-temperature phosphating at a lower temperature (typically 70 ± 5°C), and has become the mainstream process for surface treatment of steel wires before drawing.

Hold the three major international system certifications of ISO 9001, ISO 14001 and ISO 45001. We own over 20 patented technologies
Dense film layer, CuSO₄ test ≥3 min, comparable to high-temperature phosphating.
Treatment time 5–15 min, 3–5× faster than room-temperature phosphating.
Small free acid fluctuation, easy to manage, low risk of bath breakdown.
Fine crystal structure, no graying or slag inclusion, consistent quality.
Temperature 50–70°C, acid ratio 1:10–1:15, easy to operate.
Works as both a coating primer and a standalone anti-corrosion finish — one film, multiple uses.
We provide comprehensive wire production chemical solutions to global customers—from high-performance phosphating solutions to advanced dry wire drawing lubricants.
