Aluminum Circles/Discs
Aluminum circle is also known as aluminum disc, which is a perfect material for making aluminum round metal. It is usual with thickness from 0.3mm-10mm, and a diameter from 100mm-800mm. It is widely used in electronics, daily chemicals, medicine, culture and education, auto parts, and other industries. Mainly, 1xxx and 3xxx aluminum circles are used for making kitchen utensils, cookware such as non-stick pans, saucepans, pizza pans, pressure cookers, and other hardware such as lampshades, water heater casings, etc. Our aluminum circles are made in accordance with international standards ASTM B209, ASME SB 221, EN573, and EN485.
CHAL Aluminium Corporation focuses on the research and development of aluminum, we cooperate with famous academic institutions and industry associations. Our researchers and academic partners are involved in the business and technology development of aluminum product processing and production. We develop and design solutions to improve the performance of aluminum technically and economically. CHAL Aluminium Group has 5 R&D centers in China.

Why Choose Aluminum Circle/Disc to Make Cookware?
As for aluminum circle for cookware, it is vital to pay attention to flowing properties, 1xxx and 3xxx series aluminum circle has good tensile strength property, good formability, it is easy to bend. Good corrosion resistance properties can ensure cookware use for a long time. Furthermore, it requests the aluminum disc/circle has good flatness, no oil stain, and no scratches on the surface.
What is the Price of an Aluminum Circle/Disc?
In recent years, the use of aluminum circles/discs has increased. The demand for aluminum circles/discs in the market is relatively large. It is a kind of product obtained through deep processing of aluminum plates, the surface is bright and beautiful, and it can be shaped and do the surface treatment. So, it is not expensive.
The price of aluminum circles/discs has something to do with the thickness. Generally speaking, circles of a common thickness (between 1.0mm and 8.0mm) have similar prices under the condition that they entail similar manufacturing processes. Such aluminum circles/discs can be obtained through relatively simple processes. Nevertheless, if the thickness surpasses 8mm, the price will go higher because the circles have to go through hot rolling, which involves raw material loss and the application of extra equipment. Therefore, it makes sense to think that the aluminum circles/discs price is related to thickness. In spite of this, there are exceptions. As said above, the price of an aluminum circle is also influenced by its manufacturing process. Not all thin circles (thickness below 8.0mm) are produced through cold rolling, some entail hot rolling, which increases their cost and eventually impacts their price.
