In fact, the so-called tin foil is aluminum foil, not tin. "Tin foil" is just Hong Kong's name for aluminum foil. Moreover, the melting point of aluminum is 660 degrees, far exceeding the temperature of most household ovens, and will not melt during use. The melting point of tin is only 232 degrees, and many ovens can reach more than 250 degrees. If tin is used as a material, it will melt easily.
The main difference is that Aluminum foil has a higher melting point than tin foil, which is more suitable for grilling food.
Aluminum foil: It is made of metal aluminum or aluminum alloy by rolling equipment. The thickness of less than 0.025mm is called Aluminum foil, the thickness of less than 0.2mm is called aluminum foil, and the thickness of more than 0.2mm is called aluminum foil. The density of aluminum or aluminum foil is 2.70g/cm3. Melting point is 660°C. The boiling point is 2327℃, and the appearance is silver-white light metal, with ductility and malleability. It can form an oxide film to prevent metal corrosion in humid air.
Tin foil: It is made of metal tin by rolling equipment, which has excellent ductility and ductility. Therefore, it is easy to process into tin foil with a thickness of less than 0.025mm. It can even be processed by hand. The tin density is 5.75g/cm3. The melting point is 231.89°C and the boiling point is 2260°C. It has excellent ductility and malleability, good corrosion resistance and low melting point. The appearance is silvery white with blueish metal. When tin is heated above 160°C, it becomes brittle tin. The chemical properties are relatively stable and do not react with air at room temperature.
