【Concept 】
Made of aluminum pots and pans
=======================
【Features Terminology】
Lightweight / durable / fast heating / thermal uniformity / no rust
=======================
【 Material taxonomy terms 1 】
Refined aluminum ( soft aluminum ) / aluminum ( duralumin )
=======================
【2 Press Color classification terms】
White / Light Yellow / other colors
-----------------
[ White ]
Casting / stamping
---------
( 1 ) cast aluminum products
The vehicle light mechanical polishing surface treatment, surface white, but the metal loose tissue , there is a certain casting defects . Stamping of aluminum products , the surface washed , sanding and mechanical polishing treatment , the surface of the natural oxide film, a thickness of only 0.01-0.15 μm, thin and uniform , it is easy mechanical abrasion or wear.
---------
( 2 ) yellow aluminum products
Stamping anodized , so that the surface of a layer of pale yellow artificial oxide film. Thick oxide film generally 5-20μm, uniform and compact , under the action of the alkali , 100 seconds of their film is not damaged. Therefore, the best pale yellow aluminum products , it has beautiful, easy to remove dirt, corrosion resistance strong, wear resistant characteristics.

【Reaction Terminology 】
Aluminum pan in use will be black
Usually the water surface appears very clean, in fact , it contains a lot of things have been dissolved , the most common is the calcium salt, magnesium salt, followed by iron . Different sources of water contained in the iron more or less, which is to make the aluminum pan blackened iron "culprit ."
Since aluminum is more active than iron , aluminum pan and hit the water containing iron , aluminum and iron to replace out , replacing iron attached to the aluminum pan out , the aluminum pan will be darkened .
However, this chemistry " trick " to become successful , there must be three conditions:
1 iron salt water more .
2 boil water for a long time.
3 aluminum pots must be new, because the old aluminum pan surface , a thin layer of aluminum oxide , which makes the inside of the aluminum layer of aluminum oxide have no chance , " spotlight ", " magic " of course change does not become .
Since the black substance is iron , it can be removed without the black . If you want to restore luster aluminum pan , you can use vinegar to remove these black ; cook a few tomatoes and other acidic foods , but also be able to iron dissolved.
Can also be placed in a fresh apple disaster , add water , boil for a quarter of an hour , then rinse with water, the aluminum pan will become bright as new.
Cookware Cooking hinder human health
Russian medical researchers confirmed after years of research , the use of aluminum pots cooking food hamper human health. According to Russia's " Tribune " reported that Moscow Erisman Health Sciences Institute researchers found that aluminum in the human body can damage the body responsible for cell energy conversion of adenosine triphosphate , thus impeding human cell energy conversion process . The researchers believe that making use of aluminum pots acid or alkaline foods , it is easy to make aluminum dissolved in food .
