Classification of aluminum circle discs

February 17, 2020

Aluminum circle discs can be divided in a few ways: alloy, application, thickness, surface treatment and even color. Their alloys used to cover 1050, 1060, 1070, 1100, 3003, 3004 and 5052, but recently 6061 and 7075 has also been taken into account, for the application scope of the circles are being widened with development of the manufacturing process.

Application of the 1xxx discs includes cookware, kitchen utensils, containers and power battery. While 3xxx and 5xxx, boasting better performances in hardness, corrosion resistance and service life, are used in making higher end products such as pressure cookers and pots. The aluminum circle pressure cooker supplied by Haomei belongs to this group. The thickness is usually 4mm and more and diameter can be customized. Though these discs show stronger hardness, they are weaker in tensile strength and elongation, which generally reduces with the decline in aluminum content. The adding of certain alloying metals, however, can make up for this part. Take 5052 for example. Its content of magnesium offsets the loss of aluminum in elongation.

Based on inquiries of our clients, we have found that thickness has also become a key word in their demands. They might want 1mm, 3mm and 6mm etc. As a result, we have developed a 08mm 10mm thick aluminum circle to cater for special needs of clients in thickness. The thickness our production line can deal with is from 0.4mm to 10mm. The regular thickness gap is 0.5mm between two adjoining specifications, but in practice any thickness can be customized. In application, thin aluminum circle discs match disposable kettles, pots and other kitchenware which last only month, and thicker ones, like a 6mm circle sheet, usually lasts much longer after being made into daily objects.

By surface treatment methods there are mirror finish, anodized and color coated aluminum circles discs. An anticorrosion aluminum circle falls on this scope, for both anodizing and color coating aim to improve the corrosion resistance of metals. Anodizing is a method combining physical and chemical properties of aluminium. Aluminium circle pieces are kept in a chemical solution as the anode, during which a hard protective film comes into being. This extends the service life of an aluminum round sheet substantially. The color coating of aluminum discs function in the similar way. The only difference lies in the method. Here circle surfaces obtains a protective layer by paints sprayed onto them rather than chemical reactions.

Aluminum circle color changes can be realized by both anodized and color coating. With the former color on a circle surface is formed in a complicated chemical process, while with the latter paints of given colors, usually including pe, pvdf and pvc, are coated on the surface directly. Pre-painted aluminum circles, durable and corrosion resistant, are applied in fields of high pressure cookers and automobile decoration.

The most popular classification method in global market, however, is still based on application, since different end products indicate varied specifications. In other words, suppliers grasp a rough idea about specifications you need once you tell them the application, and can give you an offer on the spot. If you want kitchen utensils aluminum circle stock price, for instance, we know that you may want 1xxx or 3xxx products, and our sales manager will list you several specifications with prices for your reference.
