What are the characteristics of 1200 aluminum foil?

1200 aluminum foil is commercial pure aluminum foil and belongs to the 1xxx series of aluminum alloys. The following are its main features:

Elemental composition
Aluminum content: Typically a minimum of around 99.0%, providing high purity.
Other elements: small amounts of impurities such as iron (up to 0.50%) and silicon (up to 0.10%).

Mechanical behavior
Softness and ductility: Due to its high purity, 1200 aluminum foil is very soft and ductile, making it easy to roll, stretch and shape.
Strength: Relatively low strength compared to other aluminum alloys.
Tensile Strength: Typically ranges between 30-70 MPa (depending on tempering condition).
Yield Strength: Usually low, around 10-35 MPa.

physical properties
Density: approximately 2.71 g/cm3.
Melting point: approximately 660°C (1220°F).
Conductivity: High, approximately 61% IACS (International Annealed Copper Standard).
Thermal Conductivity: Excellent, suitable for heat exchangers and similar applications.

Corrosion resistance
Corrosion resistance: Very good due to the formation of a protective oxide layer on the surface.
Suitability: Suitable for environments where corrosion resistance is important, such as packaging, insulation and protective coverings.

surface treatment
Reflectivity: High reflectivity, making it useful in decorative applications and as a light reflector.
Appearance: Can have a glossy or matte finish, depending on the finish.

Packaging: Widely used in food packaging (e.g. wrappers, containers) due to its non-toxic and barrier properties.
Insulation: Used for thermal and sound insulation.
Electrical: Suitable for electrical applications due to its high conductivity.
Household*: Commonly found in household aluminum foil, used for cooking and packaging.

Formability
Formability: Due to its softness and ductility, it has excellent formability, making it easy to process into various shapes.

Availability
Thickness and Width: Available in a variety of thicknesses (from microns to millimeters) and widths to suit different applications.

recyclability
Recyclability: Fully recyclable, making it an environmentally friendly material.

Overall, 1200 aluminum foil is valued for its purity, excellent formability, high conductivity, and good corrosion resistance, making it widely used in a variety of industrial and household applications.
