Aluminum foil refers to paper made of aluminum foil backing paper and aluminum foil paper. It is often used to wrap food. Most of the tin foil we commonly use now is aluminum foil. So what is the difference between aluminum foil and tin foil?
Different definitions of aluminum foil and tin foil
What is aluminum foil?
Aluminum foil is a paper made by bonding aluminum foil backing paper and aluminum foil paper. It is soft and malleable, similar to paper, and does not rebound after deformation. It can be qualitative, guarantee shade, no falling, no light transmission, and no pollution, and the price is cheap.
What is tin foil?
The color of the tin foil is silvery white, and the ashes are golden yellow after burning. Its main components are tin and aluminum, which is an alloy of tin and aluminum. Its electrical and thermal conductivity are very good. It can also be fashioned into a lampshade to increase the brightness of the lamp. Tin foil is very good at insulating, and tin foil has a good finish and heat reflectivity.
Different materials and processes of aluminum foil and tin foil
Aluminum foil is made of metal aluminum or aluminum alloy through rolling equipment, and the general thickness is less than 0.025m. While tin foil is made of metal tin or tin aluminum alloy through rolling equipment.
Different physical and chemical properties of aluminum foil and tin foil
Aluminum foil has a melting point of 660°C and a boiling point of 2327°C. Its appearance is a silver-white light metal with ductility. It can form an oxide film to prevent metal corrosion in the humid air. Tin foil paper has a melting point of 231.89°C and a boiling point of 2260°C. It has the characteristics of good corrosion resistance and a low melting point. Its appearance is a silvery-white metal with a slight bluish tinge.
Different appearance characteristics of aluminum foil and tin foil
The tin foil looks much brighter than aluminum foil. The tin foil paper sold is usually stacked one by one, with cotton paper between each sheet, which is difficult to cut and expensive. While aluminum foil is stiff and easy to cut, and rolls are often used. Cartridge packaging is cheaper, so it has gradually replaced tinfoil and become the mainstream of the market.
Which is better, aluminum foil or tin foil?
Both aluminum foil and tin foil can be used to wrap ingredients for grilling to prevent the meat from scorching and maintain the flavor of the ingredients. So which one should you choose between aluminum foil and tin foil when grilling? Aluminum foil is better for grilling and wrapping ingredients.
Because tin foil is softer than aluminum foil paper, the melting point of tin foil is lower than that of aluminum foil. The temperature required for ordinary barbecued food and baked food is relatively high. Aluminum foil needs to melt at 660°C, while the melting point of tin foil paper is 231 ° C, above 160 ° C, it will start to melt. Thus, the role of aluminum foil is more extensive. Furthermore, because the aluminum foil is less expensive than tin foil, it is frequently utilized in place of tin foil in recent times.
What are the functions of barbecue aluminum foil?
Aluminum foil is often used in barbecues, it has two main functions:
1. Act as a container
Aluminum foil is comparable to a container that can stop additional grease from dripping over the charcoal fire and creating smoke. If the residual meat and grease on the grill and grill grid are not cleaned and are heated further, it is comparable to eating sticky foods. Utilizing foil paper to bake after wrapping helps to prevent issues like these.
2. Heat insulation
Aluminum foil and tin foil both have heat preservation and insulation properties. Wrapping the cooked components with tin foil allows you to hold the heat for a long time without producing too much condensation, which helps to keep the barbecue flavor.
