The aluminium sheet rate fluctuates constantly due to factors such as market supply and demand, the international economic situation, and the cost of raw materials. Generally speaking, the current rate of aluminium sheet is about $2,000-2,500 per ton. At the same time, the aluminum sheet rate with different specification will also be not the same, so when we quote for aluminium sheet product, we need the check the specification of aluminium sheet first.

 
The main reasons for the different aluminium sheet rate of different specifications are as follows:
1. Thickness and size: Aluminium sheet of different specifications require different amounts of raw materials, energy, and labor costs during the production process, and these factors will affect the price of aluminium sheets. Generally speaking, the price of aluminum sheet with thicker thickness and larger size will be relatively higher.
2. Surface treatment: Some aluminium sheet with special requirements, such as anodizing and coating, will increase production costs and lead to price increases.
3. Quality standards: Aluminum sheets of different specifications may need to meet different quality standards, such as hardness, tensile strength, surface flatness, etc., which will also affect the price.
4. Processing technology: Aluminium sheets of different specifications may require different processing technologies and equipment, which will also affect their costs. For example, some aluminum sheet of special specifications may require customized molds or special cutting, bending and other processes, which will increase production costs.
 
The main reasons why the aluminium sheet rate changes over time are as follows:
1. Raw material prices: The production of aluminium sheet requires the consumption of raw materials such as aluminum ingots, and the fluctuation of raw material prices will directly affect the price of aluminum sheet.
2. International economic situation: The global economic situation, political factors, trade policies, etc. will have an impact on the price of aluminium sheet.
3. Market supply and demand relationship: Changes in market demand, overcapacity or insufficient supply and other factors will lead to fluctuations in the price of aluminum sheet.
 
Combining the above factors, the aluminium sheet rate is a dynamic change process, which is affected by multiple factors. Therefore, the rate of aluminium sheet of different specifications will be different, and the prices will also change over time.
