Similarities between aluminum 1235 og 8079 folie.

Uses and applications

Aluminiumsfolie 1235 og 8079 aluminum foil are commonly used in packaging, including food packaging, pharmaceutical packaging and cosmetic packaging. Their value lies in their barrier properties, which can protect the contents from moisture, light and air.
8079 is more commonly used in pharmaceutical packaging.

Fysiske egenskaper

Both types of aluminum foil, 1235 og 8079, have excellent formability and can be easily converted into thin gauges. They are both highly resistant to corrosion and suitable for long-term storage of products.

Environmental benefits:

Both 1235 og 8079 aluminum foils are recyclable, meeting the growing demand for sustainable packaging solutions.

Appearance

Both types of aluminum foil typically have a shiny, reflective surface that is aesthetically pleasing and enhances barrier properties by reflecting light and heat.

Differences between 1235 og 8079 aluminiumsfolie

1. Alloy composition:

1235 aluminiumsfolie: Made primarily of 99.35% pure aluminum. This high aluminum content gives it excellent electrical conductivity and corrosion resistance.
8079 aluminiumsfolie: It contains other alloying elements, primarily iron (Fe) and silicon (Si), which are added to improve specific properties such as strength and flexibility. A typical composition might include about 0.05-0.30% Fe and 0.05-0.30% Si.

2. Mekaniske egenskaper:

1235 aluminiumsfolie: Due to the high purity of the aluminum, it tends to be softer and more flexible. It has a lower tensile strength than 8079.​​
8079 Aluminum Foil: Due to the addition of alloying elements, it has higher tensile strength and flexibility than 1235. This makes 8079 more suitable for applications that require stronger performance under pressure, such as packaging sharp items.

3. Barrier properties:

1235 Aluminum Foil: Has excellent barrier properties and is suitable for general applications.
8079 Aluminum Foil: Compared with 1235, it has excellent barrier properties, especially in terms of moisture resistance and air permeability, making it an ideal choice for more demanding packaging applications.

4. Processability:

1235 Aluminum Foil: Due to its softness, it is easier to process, making it a good choice for applications that require easy forming.
8079 Aluminum Foil: Slightly more difficult to process, but has better strength and puncture resistance.

5. Cost:

1235 Aluminum Foil:
Typically cheaper due to the higher aluminum content and simpler composition.
8079 Aluminum Foil: Typically more expensive due to the addition of alloying elements and enhanced properties.

1235 aluminum foil is ideal for general packaging and electrical applications due to its high purity, flexibility, good corrosion resistance and cost-effectiveness.
8079 aluminum foil stands out due to its added alloying elements, which provide enhanced strength, flexibility and excellent barrier properties for more demanding packaging needs.
