The melting point of cooking aluminum foil is 660 degrees Celsius, so it can be used for baking or other high-temperature heating methods and it is clean and hygienic. Aluminum foil is suitable for all types of food. These include outdoor grilling, grilling fish, oven-steaming vegetables and baking biscuits.
Generally speaking, it is used for roasting meat, fish and other foods, and when cakes have color requirements. The purpose of using aluminum foil is to facilitate the cleaning of the baking pan and to facilitate the heating of food faster.
Since the melting point of aluminum foil is 660 degrees, far exceeding the temperature of most household ovens, we of course can use it in oven. The current impact of aluminum on the human body actually refers to free aluminum ions, such as the alum used to make rice powder into rice noodles.
If such aluminum ions are taken in excess (note that the premise is excessive , this amount is not easy for ordinary people to reach), which will cause certain problems. Aluminum ions will not be precipitated only by heating.
Generally speaking, there are no strict thickness requirements on aluminum foil. The processing thicknes is usually less than 0.025mm, that is, less than 25 microns. The thickness of normal household aluminum foil is about 10-20 microns. If there is no special requirement when making it, aluminum foil of ordinary thickness is enough.
If it is only used to wrap food, you can buy 10 microns. If you use it for grilled fish, barbecue and other fatty or difficult-to-cook foods, you can buy about 20 microns. The common alloys are 1060, 1100, 3003, 8011, 8021,etc. The common tempers are H14, H16 and H18.
8011 household aluminum foil belongs to 8xxx aluminum foil. Its performance is better than that of pure aluminum foil. The common states are: H18, H16, H22, HO. It is mainly used in food packaging, pharmaceutical packaging, milk cover material, sealing foil,etc. 8011 aluminum foil is also used in cable foil, which is similar to 3003 aluminum foil, but it is not commonly used in electronic foil.
