Ultra-Precision 0.18mm MR Electrolytic Tin Plate Coils for Extreme Rust Resistance
QuanJiang's MR-grade Electrolytic Tin Plate (ETP) & Tin-Free Steel (TFS) Coils redefine rust prevention in industrial packaging. Engineered with nano-crystalline tin layering (1.1–5.6 g/m²) and chromate passivation, these 0.18mm precision coils deliver unmatched protection against salt spray, acids, and humid environments.
✔ Triple-Layer Rust Barrier
Electrolytic tin matrix (pore-free density)
Chromium oxide nano-film (0.2µm)
DOS oil coating (transport protection)
✔ Cold-Rolled Precision
±0.01mm thickness tolerance
TS230-TH620 hardness options
✔ Multi-Industry Adaptability

Q: Why 0.18mm for aerosol cans?
A: 30% thinner than standard 0.25mm, reducing weight while maintaining 120psi burst strength.
Q: Certification for food contact?
A: Complies with FDA 21 CFR 175.300 & EU 10/2011 (tin migration <0.2ppm).
Q: How does chromium enhance rust resistance?
A: Forms amorphous oxide layer blocking O₂/H₂O penetration at molecular level.
Q: Lead time for 50-ton orders?
A: 20 days with MILL CERTIFICATE and SGS test reports.
Q: Recycling compatibility?
A: Direct EAF feed – coatings vaporize at 1,550°C.
