8079 Color Coated Aluminum Coil

8079 color coated aluminum coil uses 8079 aluminum alloy as the base material. After surface pretreatment (such as cleaning and chromizing), organic coatings are applied onto the surface using a continuous roll coating process, followed by baking and curing to form a composite material.

8079 alloy is a commonly used anti-rust aluminum alloy similar to 8011, but its formulation provides superior durability, corrosion resistance, and heat insulation when rolled into ultra-thin foil. Therefore, it is widely used in pharmaceutical packaging, food containers, bottle cap sealing, home appliance panels, architectural decoration, and more.

Physical Properties

Advantages of 8079 PE/PVDF Color Coated Aluminum Coil

1. Excellent ductility and formability

8079 alloy has high elongation and does not easily crack during deep drawing, stretching, or stamping processes.

2. Strong coating adhesion

The coating is cured at high temperature and firmly bonded to the aluminum surface, ensuring no peeling or blistering.

3. Outstanding corrosion resistance

Even in humid, acidic, alkaline, or salt-spray environments, 8079 coated aluminum remains glossy and color-stable.

4. Superior decorative appearance

Available in diverse finishes: glossy, matte, wood grain, stone grain, brushed metal, etc.

5. Environmentally friendly

Free of harmful heavy metals and compliant with EU RoHS, suitable for food and pharmaceutical packaging.

Applications

• Pharmaceutical packaging: blister packs, aluminum-plastic sealing lids

• Food packaging: chocolate, milk powder, instant coffee, and other outer packaging

• Bottle caps: anti-theft caps, easy-open caps, pharmaceutical aluminum caps

• Architectural decoration: façade panels, roofing systems, ceiling panels, louvers

• Home appliances: refrigerator panels, microwave oven shells, decorative panels

• Transportation: interior trim panels, reflective panels, ship decoration components

Color Options

Common Coating Types

PE (Polyester Coating): Cost-effective, vibrant colors, excellent flexibility.

PVDF (Polyvinylidene Fluoride): Ideal for outdoor applications with high weathering resistance.

Epoxy / Special primers: Used for food and pharmaceutical inner packaging requiring specific barrier performance.

Comparison with 8011 Coated Aluminum Coil

Composition & Performance:

8011 coated aluminum coil usually has higher silicon content and may contain Mn and Mg, giving it higher strength and corrosion resistance.
8079 aluminum coil provides better elongation and puncture resistance.

Applications:

8011 aluminum is used widely in food packaging, pharma packaging, bottle caps, cable foil, etc.
8079 coil is preferred for pharmaceutical blister packs and lithium battery soft packaging due to its forming ability and barrier performance.
