Core Characteristics of 8079 Ju'un aluminio
The excellent performance of 8079 aluminum foil stems from its precise chemical composition ratio and advanced production process. Its core characteristics meet the needs of various high-end application scenarios, distinguishing it from ordinary aluminum foil models. The specific advantages are as follows:
-
Precise Chemical Composition Ratio: The main component is aluminum (balance), with silicon (Wa) content of 0.05~0.30%, iron (Fe) content of 0.7~1.3%, cobre (Cu) ≤0.05%, zinc (Zn) ≤0.10%, single other impurity ≤0.05% and total other impurities ≤0.15%. No manganese (Mn) element is added, balancing strength and ductility, suitable for high-end packaging and deep processing needs.
-
Excellent Mechanical Properties: The tensile strength can reach 65-100N/mm², and the elongation is ≥15%, which is far higher than the ordinary aluminum foil standard. It can still maintain good toughness in the thin gauge (such as 7μm), not easy to break or puncture, and can meet the deep processing needs such as stamping and bending of complex shapes, especially suitable for high-demand scenarios such as pharmaceutical PTP aluminum foil.
-
Outstanding Surface and Barrier Properties: Adopting high-precision foil rolling process, the surface is smooth and free of defects, clean of oil, with pinhole number ≤150 pieces/m², which is much lower than the industry average level; it has excellent moisture-proof, air-tight and light-shielding properties, with oxygen transmission rate (OTR) <0.1cm³/(m²·24h·atm), which can effectively isolate moisture, oxygen and light, and extend the shelf life of packaged products.
-
Good Processing and Adaptability: It supports various processing methods such as tandem rolling, slitting and heat sealing. With high surface dyne value, it is suitable for subsequent processes such as printing and lamination, and can meet the needs of packaging marking and composite molding without additional treatment; it can provide various states such as O state (Soft State), H22 and H24 to adapt to the processing requirements of different industries.
-
Safe, Environmentally Friendly and Economical: It meets food-grade and pharmaceutical-grade standards, non-toxic and tasteless, with no harmful impurities precipitated, suitable for direct contact with food and drugs; 100% reciclable, retaining 95% of the original metal value during recycling, and the recycling energy consumption is only 5% of primary aluminum production, balancing environmental protection and cost control; compared with 1235 ju'un aluminio, although the unit price is slightly higher, the total packaging cost can be reduced by about 10% by reducing the loss rate.

8079 Aluminum Foil Production Process (Controllable Quality, Traceable)
We adopt industry-leading production processes, strictly follow ISO quality system standards, and conduct full-process control from raw materials to finished products to ensure that each batch of 8079 aluminum foil has stable quality and up-to-standard performance. The production process is as follows:
-
Raw Material Screening: Select high-purity aluminum ingots and high-quality alloy raw materials, strictly control impurity content to ensure that raw materials meet 8079 alloy composition standards; at the same time, 0-40% qualified scrap can be added to balance environmental protection and cost control; during melting, strictly control melt hydrogen content ≤0.12ml/100gAl to avoid air hole defects in finished products.
-
Melting and Casting Forming: Put the screened raw materials into the melting furnace, melt them into melt at high temperature, and after degassing and filtering treatment, cast into ingots to form blanks, ensuring uniform composition, no impurities and no air holes of blanks, laying the foundation for subsequent rolling.
-
Hot Rolling and Cold Rolling: Hot roll the ingot blank to 3.0-5.0mm thick slab at 320-360℃, control convexity rate ≤1.0%; then perform two passes of cold rolling, when the thickness reaches 0.8-1.5mm, perform intermediate annealing treatment at 310-360℃ for 2-4h, and finally cold roll to 0.24-0.30mm aluminum foil blank.
-
High-Precision Foil Rolling: Use high-precision foil rolling mill to roll the aluminum foil blank to the target thickness (0.006-0.2milímetro) according to the specified reduction, and tandem rolling can be performed to make double thin-gauge aluminum foil; during rolling, control roll crown 60-100%, roughness 0.04-0.085μm, add 6-12% high dyne value additive, and oil temperature ≥40℃ to ensure smooth surface, uniform thickness and up-to-standard pinhole rate of finished products.
-
Slitting and Inspection: According to customer needs, slit the aluminum foil to the specified width and length, strictly control edge flatness during slitting, no burrs and no deviation; finished products are inspected in multiple dimensions such as appearance, espesor, mechanical properties and pinhole number, and unqualified products are eliminated to ensure 100% up-to-standard products leaving the factory.
-
Packaging and Warehousing: The inspected 8079 aluminum foil is packaged in moisture-proof and dust-proof way, marked with product information (grade, specification, batch, production date) for traceability; after warehousing, it is stored in classification, with moisture-proof and sun-proof treatment to ensure the storage quality of products.
