De ce aluminiul este bun pentru a face ghivece?

Aluminiul în sine are caracteristicile unei greutăți ușoare, transfer de căldură bun, rezistență la oxidare și nu ușor de ruginit, astfel încât oala de aluminiu are avantajele unei greutăți reduse, transfer de căldură bun, economie de combustibil și economie de timp.
Aluminiul are o peliculă densă de oxid pe suprafața sa, which protects the aluminum inside from oxidation.

We should pay attention to the use of aluminum cooking utensils:

Do not use to hold acid, alcaline, pickled food, do not scratch the oxide film.

There is a difference between aluminum and aluminum alloys. Aluminum is used to make cooking POTS, soup POTS. Use is not a problem, because the temperature is low, will not precipitate aluminum ions. But can not do the wok, because the temperature is high, and there is oil, sare, sauce and vinegar, will precipitate aluminum, affecting health. But aluminum alloy can do wok, because aluminum alloy structure is stable, basically will not precipitate aluminum.
