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.
