T4 MR Grade Electrolytic Tinplate Coils with BA/CA Temper for Food and Aerosol Can Manufacturing

T4 MR Grade Electrolytic Tinplate Coils represent high-quality tin-coated steel materials specifically engineered for premium packaging applications. These coils feature a precise electrolytic deposition of pure tin on cold-rolled low-carbon steel substrates, creating exceptional corrosion resistance and manufacturing versatility. The MR grade designation ensures superior material purity and consistency, while the T4 temper provides optimal balance between formability and strength for intermediate drawing applications. Available in both Bright Annealed (BA) and Clean Annealed (CA) surface finishes, these coils accommodate various production requirements and end-use specifications. With thickness ranges from 0.15mm to 0.47mm and customizable tin coating weights, this material meets international standards including JIS G3303, DIN, and ASTM specifications.
