Advanced Chrome-Coated Electrolytic Tin Plate for High-Performance Food & Industrial Can Manufacturing

Advanced Chrome-Coated Electrolytic Tin Plate for High-Performance Food & Industrial Can Manufacturing

        QuanJiang's SPTE/TFS Chrome-Coated Electrolytic Tin Plate redefines corrosion protection for metal packaging. Combining a chromium underlayer with electrolytic tin plating, this material delivers dual-barrier defense against aggressive contents (acids, oils, chemicals) while enabling superior paint adhesion. Certified to JIS G3303, DIN, ASTM, and GB standards, it excels in food safety and industrial durability.

Breakthrough Features

✔ Hybrid Coating System

• Chromium layer: Enhances paint bonding (3× stronger vs. standard tinplate)

• Electrolytic tin: Sacrificial corrosion protection for acidic/alkaline products

✔ Precision Hardness Grading

• DR7.5-DR10: Engineered for high-stress components (can ends, pressure vessels)

• T1-T5: Balanced formability for deep-drawn cans

✔ Eco-Conscious Production

• Chromium reduction technology: 40% less chromium vs. conventional TFS

• Fully recyclable: Meets ISO 14000 sustainability standards

Technical Specifications

Competitive Advantages

• Supply Chain Efficiency: 50,000 MT/month capacity; 30-day lead time at 50MT MOQ

• Processing Versatility: Optimized for welding, stamping, and high-speed printing

• Cost Savings: Chrome layer eliminates need for primer in 70% of paint applications

Industry Applications

FAQ

Q: How does chromium enhance tinplate performance?

A: Chromium forms a microcrystalline barrier that prevents under-film corrosion while enabling direct printing without primers.

Q: When to choose DR10 over T5 temper?

A: DR10 (73+ HR30T) for pressure-bearing can ends; T5 (65 HR30T) for deep-drawn bodies requiring formability.

Q: Compliance for EU food contact?

A: Exceeds EC 1935/2004 migration limits – chromium release <0.01mg/kg.

Q: Minimum order flexibility?

A: 50MT base MOQ; sample coils available (3-5kg) with SGS test reports.

Q: Packaging for humid climates?

A: VCI rust-proof paper + desiccant capsules in sealed wooden crates.
