Aluminium foil

Classification of Aluminium Foil

Aluminium foil classified by thickness:

• T＜001 – light gauge foil (also called double zero foil)
• 1≤ T ≥0.001– medium gauge foil (also called single zero foil)
• T ≥0.1mm– heavy gauge foil

Aluminium foil classified by composite material:

• Flux clad aluminium foil
• Zinc coated aluminium foil
• Bare aluminium foil

Aluminium foil classified by alloy grade:

• 1xxx series: 1050, 1060, 1070, 1100, 1200,1350
• 2xxx series: 2011, 2024
• 3xxx series: 3003, 3104, 3105, 3005
• 5xxx series: 5052, 5754, 5083, 5251
• 6xxx series: 6061
• 8xxx series: 8006, 8011, 8021, 8079

How To Choose Aluminium Grade?

When we choose aluminium, it is important to note that choosing the right alloy is directly dependent on the properties and the specific using scenario. Before you purchase aluminium grade, it is vital to pay attention to flowing properties:

• Tensile Strength
• Thermal Conductivity
• Weldability
• Formability
• Corrosion Resistance

Applications of Aluminium Foil

Aluminum foil can be used for a wide range of applications:

• Automobile application
• Heat transfer (fin material, weld tube material)
• Packaging
• Packaging
• Insulation
• Electromagnetic shielding
• Cooking
• Art and decoration
• Geochemical sampling
• Ribbon microphones

Advantages of Aluminium Foil

• Aluminium foil has a shiny metallic luster, decorative.
• Non-toxic, tasteless, odorless.
• Relatively lightweight, the proportion is only one-third of iron, copper.
• Full-extension, thin, low weight per unit area.
• Blackout good, reflective rate of 95%.
• Protection and strong, so the package less susceptible to bacteria, fungi and insects infringement.
• High and low-temperature stability, temperature -73 ~ 371 ℃ without deformation sizing.

Why Use Aluminium Foil?

Aluminium foil is prepared in thin sheets and used in a wide range of applications, from everyday household foil to heavy-duty, heat-resistant industrial foil rolls. Aluminium foil is extremely pliable and can be bent or wrapped around objects with ease. Typical finishes are available in pack rolled (one side bright/one side matte), two sides polished and mill finish. Millions of tons of aluminium foil are used throughout the world to protect and package foods, cosmetics and chemical products. Aluminum is a durable and easily used material, making it an ideal option for several industrial applications.

How Do I Know Which Aluminium Foil To Use?

Standard Aluminium Foil – Great for wrapping lighter individual items and covering containers for storage. Our aluminium foil is 0.0005 – 0.0007 thick.

Heavy Duty Aluminium Foil – Is used in cooking situations for lining pans and cooking sheets. Great for moderate heat. The CHAL heavy duty foil is 0.0009 thick.

Extra Heavy Duty Aluminium Foil – Ideal for high heat situations and heavy wrapping situations. Great for lining grills and coming in direct contact with flames. To be used for wrapping heavy meats such as briskets and slabs of ribs. The CHAL extra heavy duty foil is 0.0013 thick.

Is It Safe to Use Aluminium Foil?

Aluminum is one of the most abundant metals on earth. It’s naturally occurring in most foods, including fruits, vegetables, meats, fish, grains and dairy products. Besides, some of the aluminium you eat comes from processed food additives, such as preservatives, coloring agents, anti-caking agents and thickeners.

Regardless, the aluminum content of food and medication isn’t considered a problem, as only a tiny amount of the aluminum you ingest is absorbed. The rest is passed in your urine feces. Furthermore, in healthy people, absorbed aluminum is later excreted in your urine.

So, the small amount of aluminium you ingest daily is considered safe.

Equipments For Making Aluminium Foil

3300mm + 2800mm  “1+1” hot mill

• MINO auto control system imported from Italy, with high machining accuracy (thickness tolerance±0.2mm).
• High rolling force on 3300 rough hot rollings, to realize the rotated rolling with the excellent control of thickness and flatness.
• The auto control system enables the precise machining on 2800 finishing rolling.
• Able to operate separately to improve efficiency and reduce cost.

2800mm Cold Roll Machine

• The oil cold rolling mill of aluminium alloy plate and strip which designed and refitted by Italy Mino, has abilities of large rolling force, wide width cold rolling, plate finishing and roughening rolling.
• By adopting the latest technology coupled with computer simulation and finite element method, the maximum rolling force can reach 3000 tons and the maximum rolling width can reach 2600mm.
• It is the only one ultra-wide all-in-one plate and coil machine in domestic can compare with SWA’s 1600mm mill and Alcoa’s 2600mm mill.

Cold Roll Mill

• From ACHENBACH. Electrical drive, AGC and AFC system integration from MINO Italy. Supporting with gauge tester and BETA laser velocimeter well control the accuracy, to ensure the thickness tolerance and flatness requirements.
• Disc scissor frame and blade imported from Germany, to guarantee the shearing precision, which can well meet the requirements of width tolerance and edge burr rate.
• The nitrogen protected annealing furnace imported by a Germany junker company, which can guarantee the surface quality.
