How to judge quality of aluminum cookware by colors

2018-03-26


Speaking of how to judge quality of aluminum cookware, people may have various answers based on their own life experience. Some may say, for example, that you should observe the surface to make sure there are no cracks, spots or other defects. Some people may tell you to feel the weight of a pot. Others may suggest knocking a pot by your fingers and hear the sound it gives off. All the tips above prove to be very useful. However, there is a much easier tip which you may have never heard of.

The secrete is, you can judge the quality of aluminum cookware simply by colors. Aluminum products can be roughly divided into two parts by processing methods--refined aluminium (soft aluminum) and cast aluminium (hard aluminum). Their colors include white, light yellow and other colors. White products have gone through casting or punching. Cast products, polished mechanically, have loose structures. Punched products, which have been washed and polished by mechanics and sand, have a thin layer of uneven natural oxidized layer that gets damaged very easily. Yellow aluminum products, however, has a layer of light yellow man-made film of five to 20μm. The film demonstrates strong corrosion resistance to alkali. Therefore, light yellow aluminum products boasts good look, easy cleaning, strong corrosion resistance and excellent wear resistance. That’s why aluminum cookware wins so much popularity.

In a word, if we judge the quality of aluminum cookware by colors, light yellow cookware should be the best. Haomei has decades of aluminum manufacturing experience and over ten years of export history. Welcome to contact us at april@aluminumhm.com or wechat/mobile 008615838029491 for more information.
