Aluminum pan selection, use and precautions

(1) Features
Alloy aluminum pan lightweight, durable, fast heating, thermal uniformity, no rust, but should not be used to cook acidic or alkaline foods and salty foods, otherwise, the aluminum cookware will be a substantial dissolution of contaminated food.
Alloy aluminum products are mainly two natural hair color and hard anodized aluminum and aluminum alloy materials. Surface color can be divided into white, pale yellow, black and other colors. White aluminum casting and stamping products are divided into two kinds. Cast aluminum products (known as traditional steel pan around 10-20 dollars) by surface car light and mechanical polishing treatment, surface white, but loose metal structure, there are some casting defects. Stamping aluminum products, the surface washed, sanding and polishing machine, the surface of the natural oxide film thickness of only 0.01-0.15 μm, thin, uneven, easily scratched or worn machinery. The yellow aluminum products is stamping anodized to the surface of a layer of pale yellow artificial oxide film. General oxide film thickness 5-20μm, uniform and compact, under the strong base effect, the film does not destroy its 100 seconds, while the black oxide film can be as thick as 30 microns -50 microns, surface temperature up to 2500 degrees Celsius, strong acid and strong a base, the surface oxide film is not damaged. Therefore, the best black aluminum, it has a beautiful, easy to remove dirt, corrosion resistance strong, wear resistance characteristics.
Daily life, many people like to use an aluminum pan pot scourer to highly polished, although experts say this is wipe the stains on the pot, but also wipe the surface of aluminum cookware has a protective effect of the oxide film . Therefore, the use of aluminum pots, aluminum pots and other aluminum cookware, do not wipe the surface of the pale yellow film.

(2) Select
In the selection of alloy aluminum pan or pot, the pot should be noted that positive body straight round, bottom of the pot, lid and inside and outside bright, no dark, black scars or cracks, and to check parts of the structure, such as rivets, ring top portion is solid, Have pitting, trachoma.

(3) protect the pot
Avoid using steel wool scrubbing. Coke bottom overtime boiled, soaked with a scouring pad to clean. Time rarely serve food in the pot.
