1235 Aluminum Foil For Lamination
1235 Aluminum Foil For Lamination, as one of the pure aluminum foil series products, has good rust resistance, formability and solubility. The cutting will not deform, the adhesive is not easy to fall off, and the printing effect is excellent. 1235 Aluminum Foil For Lamination is used as raw material. After post-compounding, printing, bonding and other processes, it has the characteristics of good heat preservation, strong adhesion and anti-aging.Aluminum foil 1235 is an aluminum foil with aluminum content not less than 99.35%, and can process 1235 aluminum foil with a thickness of 0.018-0.5 mm. Due to its excellent anti-rust properties, formability and weldability, this product is widely used in cables, tapes, batteries. in foil.
Since the soft texture of aluminum, good ductility and silvery white luster, if the rolled sheet is mounted on offset paper with sodium silicate and other substances to make aluminum foil, it can also be printed. However, the aluminum foil itself is easily oxidized and the color becomes darker, and the color will be faded by friction and touch, So it is not suitable to hot stamp the covers of books and periodicals that have been preserved for a long time.
The 1235 alloy billet with a thickness of 4 ~ 6mm is produced by the twin-roll continuous casting and rolling mill, the Fe content is controlled at 0.2 ~ 0.45wt%, the Si content is controlled at 0.05 ~ 0.15wt%, and the remaining alloy elements are controlled at the nominal composition of the 1235 alloy The cast-rolled strip is cold-rolled once to a thickness of 0.5-0.7 mm; the cold-rolled strip is then subjected to high-temperature annealing in the temperature range of 400-500 ° C for 4-8 hours, and after annealing, the two strips are annealed. Secondary cold rolling to a finished thickness of 0.28 ~ 0.35mm.
