The difference between 2A11 and 6061 aluminum plate

Edit:admin Date: 2018-03-12 17:05
2A11 aluminum plate and 6061 aluminum plate are both heat treatable aluminum alloys, and the finished products of them are difficult to distinguish in appearance, but the price difference is huge. The average price gap is about 10,000 yuan per ton. What are the reasons? What is the difference between these two aluminum alloy products?
First, the hardness of 2A11 aluminum plate and 6061 aluminum plate is very different. 6061 aluminum alloy after heat treatment hardness of about 90HB, while the hardness of 2A11 aluminum plate can reach 120HB, 2A11 belongs to ultra-high strength aluminum alloy, also belongs to the high-end products in the aluminum plate, so few domestic manufacturers can produce it. While Mingtai Aluminum is one of the few privately-owned aluminum processing companies that can produce 2A11; and the processing requirements for 6061 aluminum are relatively low, and almost all manufacturers can produce it.

Second, the density is different. 6061 aluminum plate density is 2.7, and 2A11 because of high copper content, density in the vicinity of 2.78-2.79, according to the weight to calculate the product density. Formula: Thickness * Density * Length * Width = Weight.
Third, the use of them is different. 2A11 aluminum plate is mainly used in high-end products, such as: military, aerospace, high-precision molds, etc., and 6061 aluminum alloy is widely used, taking 6061 aluminum plate of Mingtai Aluminum as an example. The product is in the wheel hub of automobile card, mobile phone shell, and mobile phone. Card slots, subway light rail cars and other aspects have a wide range of applications.
