what is 3mm aluminum sheet


3mm aluminium sheet is 3mm thick aluminium sheet, which represents an aluminium sheet with a thickness of 3mm. In fact, 3mm thick aluminium sheet and 2mm thick aluminium sheet are common thickness, and are also commonly used thicknesses. Aluminium sheets of different alloys can be rolled into different thicknesses such as 2mm / 3mm by rolling mill. Aluminum alloys such as 1050, 1060, 1100, 3003, 5052, 5083, 5086, 5454, 5754, 6061, 6063 and 7075 can be processed to the above thickness. 3mm thick aluminium sheet retains the same aluminum characteristics as other thickness aluminium sheets.

Features of 3mm aluminium sheet:
The aluminium sheet has a low melting point and good casting properties, and its mechanical properties are closely related to its purity. Pure aluminum 3mm aluminium sheet has low strength, but maintains the characteristics of pure aluminum and has high plasticity. The alloy 3mm aluminium sheet not only maintains the characteristics of aluminum, but also significantly improves its hardness and strength. Close to or exceed high quality steel. Aluminum alloy has excellent ductility and can be processed by various methods. The formability of pure aluminum and aluminum alloys is affected by their chemical composition, grade and heat treatment.

3mm aluminium sheet price:
To know the specific 3mm aluminium sheet price, you need to sort out some issues first.
In theory, 3mm aluminium sheet price has nothing to do with the thickness, because we usually quote in metric tons. However, the smaller the thickness, the higher the price, but this is not absolute.
Generally speaking, 1xxx aluminium sheet is the cheapest, while 3xxx, 5xxx, 6xxx, 7xxx are more expensive in turn, because they are related to different processes and tempers.
3mm aluminium sheet price will be affected by some factors. Such as alloy, temper, surface treatment methods and delivery costs. Therefore, if you really want the 3mm aluminium sheet price, please send the complete details of the sheet to your supplier.

Share with you how to judge the quality of 3mm aluminium sheet:
Aluminium sheet is a very important industrial raw material, so the quality requirements are very strict. When we want to buy 3mm aluminium sheet, we should first judge the quality of aluminium sheet and the strength of aluminum sheet supplier.
The first is the chemical composition. If a large amount of aluminum or scrap aluminum is mixed into the 3mm aluminium sheet, its cost will be greatly reduced, but the chemical composition is not qualified, also the quality will not be qualified.
The second is processing technology. The inferior aluminium sheet greatly reduces the processing steps and the loss of chemical reagents. This can reduce costs, but the corrosion resistance is greatly reduced.
Third, we need to pay attention to the oxide film on the surface of the aluminium sheet when buying. For aluminium sheets with a thickness of less than 3mm, if the oxide film is thin and the thickness is insufficient, the aluminum surface is prone to rust and corrosion.
