錫箔とアルミ箔–Comparison between Aluminum and Tin
Aluminum foil and tin foil are both thin metal packaging materials, which are widely used in many aspects of life. Tin foil and aluminum foil have their own characteristics, some similarities, and many differences.

錫箔とアルミ箔

Differences in composition

What is tin foil?

Tin foil is a thin sheet made of tin metal, usually made of pure tin or tin alloy, and may also contain aluminum to form tin-aluminum alloy. Tin foil has high plasticity and heat resistance and is widely used in many fields.

What is aluminum foil?

Aluminum foil is a hot stamping material that is directly rolled into a thin sheet with metal aluminum. It has a very thin thickness. The hot stamping effect of aluminum foil is similar to that of pure silver foil, so it is also called fake silver foil. Aluminum foil has a soft texture, good ductility, and a silvery-white luster. If the rolled thin sheet is mounted on offset paper with sodium silicate and other substances to make aluminum foil, it can also be printed..

Comparison of melting points of aluminum foil and tin foil

Aluminum and tin are two different metals, and there are also obvious differences in melting points.

Melting point of aluminum foil

Melting point temperature: The melting point of aluminum foil is relatively high, reaching 660℃. This means that during regular cooking and heating, aluminum foil can remain stable and is not easy to melt. Due to the high melting point and good physical properties of aluminum foil, it is often used in oven cooking, 食品包装, and occasions that require high temperature treatment.

Melting point of tin foil

Melting point temperature: The melting point of tin foil is relatively low, generally between 215℃ and 231.89℃. The melting points of tin foil of different thicknesses and materials may vary. Tin foil is mainly used in food packaging, 医薬品の包装, and cosmetic packaging, but its use is subject to certain restrictions in occasions that require high temperature treatment, such as oven cooking.

Tin vs aluminum foil density comparison

Density is a basic property of a substance. There is a big difference in density between two different metals, aluminum foil and tin foil.

Density of aluminum foil

The density of aluminum foil is about 2.70g/cm³. This value is the density of aluminum or aluminum alloy after being processed into aluminum foil, which is similar to the density of pure aluminum. As a rolled product of metal aluminum or aluminum alloy, aluminum foil inherits the lightness of aluminum, making aluminum foil widely used in packaging, building insulation and other fields.

Density of tin foil

The density of tin foil is relatively high, ranging from about 5.75 to 7.31g/cm³. Different data may give slightly different values, which may be due to factors such as the purity and processing method of the tin foil. The high density of tin foil gives it better ductility and corrosion resistance, but it also makes it relatively heavy. Tin foil is also used in packaging, 電気, construction and other fields, but due to its high cost, it is usually used in occasions with high performance requirements.

The density of aluminum foil is significantly lower than that of tin foil, which makes aluminum foil more advantageous in occasions where lightweight materials are required. Due to the difference in density, aluminum foil and tin foil also have different application fields. Aluminum foil is widely used in food packaging, building insulation, electronic component protection and other fields due to its light weight, plasticity and cost-effectiveness; while tin foil has more professional applications in electrical, chemical, medical and other fields due to its high ductility, corrosion resistance and good conductivity.

Differences in physical properties between tin foil and aluminum foil

Aluminum foil has a silvery-white appearance and good ductility. In humid air, aluminum foil can form an oxide film to prevent metal corrosion, which further enhances its durability.
Tin foil also has good oxygen and moisture insulation properties and plasticity, but its stability at high temperatures is not as good as aluminum foil.
