The price of 2mm thick anodized aluminium sheet is not stable, for the conditions needed for a quotation are not enough. If you need to get the price of a product from an aluminium sheet supplier, you should at least provide quotation elements of alloy, temper, thickness, size and surface treatment. As we can see, the long phrase “2mm thick anodized aluminium sheet” include only thickness (2mm) and surface treatment method (anodized), excluding alloy, temper and size, thus it’s impossible for a responsible supplier to give you an offer. The other way proving to be easier to obtain a price is to tell a supplier the end usage of an aluminium sheet you need, like 2mm (thickness) anodized aluminium sheet (surface and product type) for insulation (use), then your supplier would recommend specifications based on your local conditions, from which you can just pick out the most cost efficient one.
Some people might believe that the phrase is really long enough. Definitely it’s long, but it’s not enough. Almost all alloys of aluminium sheets, from 1xxx to 7xxx, can be made into 2mm. 8xxx is an exception, since it’s more frequently made into thin aluminium foil rolls less than 0.2mm thick. Based on your requirement above, you get 1050, 1060, 1070, 1100, 2024, 2a04, 3003, 3004, 3005, 3105, 3105, 5005, 5052, 5083, 5754, 6061, 6082, 7075 and so on. These are only the common alloys. And tempers for these alloys ranging from O to H112, and T1 to T651! If you think you can just mix a specification based on what I said, you are too naive, for there’s no such a product like 2mm 1050 T6 anodized aluminium sheet. The reason is that 1050 can not be made by T states. Therefore, you need to make a study before sending an inquiry, or else you will make a fool of yourself without realizing it, and your suppliers would find out immediately that you are a green hand whose money is easy to get.
