HJ GROUP leads the industry with advanced electrolytic chromium coating technology, delivering high-performance TFS for demanding global markets:
Key Features
● Corrosion Resistance: Chromium oxide layer (0.2-0.5g/m²) provides superior protection against sulfide and chloride attack
● Surface Quality: Mirror-like finish (Ra ≤0.8μm) supports high-definition lithographic printing
Formability: Yield strength 240-340MPa with excellent deep-drawing capability
Sustainability: Tin-free composition reduces environmental impact while maintaining recyclability
2. Universal for food/non-food metal packaging (processed meats, dry goods, coatings, chemicals), supplied as loose parts for self-assembly with independent forming equipment.
