0.5 mm aluminium sheet price

0.5mm aluminium sheet price is higher than prices of thicker aluminum sheets, for the production of 0.5mm sheets entails more rolling steps. The production procedure consists of melting and casting ingots-heating, hot rough rolling, hot finishing rolling, straightening, shearing, sawing, sampling, testing, inspection and acceptance, packaging and warehousing. Thick aluminum plates can be obtained by only rough rolling and finishing rolling, but thinner sheets can not be acquired unless by continuous rolling steps. Ordinary finishing rolling machine only yield sheets as thin as 1.7mm, if you need thinner ones like 0.5mm alu sheets, preciser rolling steps are adopted.

The thickness of a 0.5mm aluminium sheet is near to that of aluminium foil, the thickest of which is 0.2mm. The production of aluminium foil include extra rolling steps: rolling, precise rolling, second precise rolling etc. And the price for aluminum foil rolls are no less than $2750/mt in the market. Therefore, extra manufacturing processes add to the the 0.5mm aluminum sheet price.

Specific prices of 0.5mm aluminum sheets are also related to alloys of a sheet. Almost all 8 series of alloys can be made into 0.5mm sheet, especially those of 8000 series, which are usually raw materials for aluminium foils. 6000 and 7000 sheets are seldom less than 0.6mm thick. It’s not that current technology does not reach that level, but that most of their applications decide the thickness must be bigger than 0.5mm, mostly than 1mm. For the two series of aluminium sheets are hard in strength and excellent in mechanical properties, and they are frequently applied to weight bearing panels for cars, vehicles, planes and so on. The 0.5mm sheets are usually of 1xxx, 3xxx or 5xxx series. Thin as they are, they bear no weight in applications, and their basic corrosion resistance and hardness are enough for regular conditions. This is a good thing, for aluminium sheets of these alloys are usually cheaper than 6000 and 7000 alloys. Of course, no precise offers could be given until you send details.
