What influences aluminium circle price
The aluminium circle price fluctuates day by day. However, it does not change randomly. The price has something to do with aluminum ingot price, rolling way, alloy, surface treatment process etc.
As a raw material for all aluminium products, aluminum ingot price is closely related to the price of electricity, relation between demand and supply of oxide aluminium, demand of aluminium sheet roll products and even economic situation. Any changes in these complicated factors result in fluctuation of the price of aluminium round sheets.
Rolling way refers to whether the aluminium disc circles are made by cold or hot rolling aluminum process. Hot rolled circles are more expensive because the process costs extra time and money. Needless to say, their performances overshadow cold rolled pieces as well, especially in elongation.
Alloy refers to the aluminium grade of which a circle is made of, regularly incorporates 1050, 1060, 1070, 1100, 3003 and 5052. 3xxx and 5xxx circle price is higher than 1xxx sheets of the same size and surface treatment methods, for they contain more alloying metals that function to improve the sheet’s hardness and corrosion resistance. For example, 1060 aluminum circle price is lower than that of 3003 circle for cookware.
Surface treatment methods for aluminium circles mainly include anodizing and color coating, both of which prove to be costly. Anodizing is an electrolytic process stimulating the birth of a hard protective layer on the sheet surface, and color coating a physical process of coating PE or PVDF paint on the surface. Both processes are used in production of high-end products like alu disc for pressure cookers.
The factors above are key elements impacting the price of aluminum circle sheets. In addition, other aspects, such as delivery cost, currency exchange rate and so on, cause fluctuation of the price, too. Foreign purchasers are advised to learn something about China aluminium index market before putting orders to aluminum discs suppliers.
