Type: ultra-Thin Micron-Tolerance Electrolytic Tinplate (ETP) Coils, Strips & Sheets.
Model: T5/DR7/DR8 High-Temper
Params: 1. High-Hardness Bending Cracking - SOLVED: Bridges the metallurgical gap of high temper/double-reduced hardness (T5, DR7, DR8) and ultra-thin gauges (0.17mm - 0.19mm), ensuring tight-radius bending without structural splitting.
2. Knife-Edge Maritime Rusting - ELIMINATED: Advanced online post-slitting blade-cut oil-spraying passivation completely prevents edge corrosion, custom-engineered for high-humidity transit and tropical storage.
3. Decorative Surface Flaws - PREVENTED: Enforced via a strict "5-ZERO" screening protocol to guarantee 100% certified ZERO joints, ZERO notches, ZERO wavy edges, ZERO overlap ribbons, and ZERO rust spots on premium appearance faces.
4. Tooling Wear & Material Jamming - MINIMIZED: Rigid micron-level geometric controls with thickness tolerance at ±0.005mm, width tolerance at ±0.05mm, and burrs restricted under ≤0.05mm to maximize progressive die lifespan.
5. Global Sourcing Compliance - GUARANTEED: Certified under the French Bureau Veritas (BV) ISO 9001 quality framework, delivered in standardized single-coil individual protective packaging with batch-traceable Mill Test Certificates.
Material: Prime Quality Electrolytic Tinplate (ETP) Base Metal with 2.8/2.8 Tin Coating Weight.
Applicable Industry: High-End Hardware Manufacturing,packages, and Premium Consumer Electronic Enclosures.
