4x8 sheet aluminum for sale, also known as 4'x8' aluminum sheet, refers to a type of aluminum sheet with a width and length of 4 inches and 8 inches. There are many aluminum alloys, mainly due to their many properties, such as high strength, weight ratio and corrosion resistance. Another reason behind its popularity is its flexibility, which allows the manufacture of various alloys with slightly different properties.
The hardness of the aluminum sheet determines whether the bending cracks. The hardness of the aluminum sheet is too high, and it is easy to crack. The hardness of the aluminum sheet is related to the alloy and temper of the aluminum sheet.
Aluminum sheet alloy series that can be bent: Generally, the aluminum sheets of the 1 series, 3 series, and 5 series are often used for bending.
The 6 series and 7 series have high hardness and are generally made of medium-thick aluminum sheets, which are not used for bending. If you are bending, you need to be annealed to O temper before you can bend.
There is residual oil on the surface of 4x8 sheet aluminum for sale, which may cause oil spots and stickiness in severe cases. The real cause of oil stickiness is that the surface is not clean. The following measures can be taken to reduce the residual oil on the surface of the aluminum sheet.
First, during the rolling process of 4x8 sheet aluminum for sale, the intermediate purging and oil removal can greatly reduce the residual oil on the surface. If the oil baffle and splash plate are installed on the roll, it can block the oil coming from the roll neck and roll gap, and fully catch the rolling oil falling from the surface of the upper work roll.
Second, select the appropriate rolling speed and coiling tension.
Third, choose suitable rolling oil and prevent rolling oil pollution.
Fourth, the coiling void ratio during slitting should not be too small, and edge warping should be avoided, so as not to affect the effect of annealing and degreasing.
Fifth, choose a suitable annealing system, and the annealing temperature of the aluminum sheet should not be too high. The annealing time is longer, and step annealing can also be used.
Unit price of aluminum sheet = price of aluminum ingot + processing fee. The price of the aluminum ingots of the Yangtze River can be found online. If you want to know quickly, you can directly consult us. Different manufacturers have different processing fees for aluminum sheets, and different alloys and different tempers have different processing fees for aluminum sheets. Taking 1060 as an example, if the unit price of a 1mm thick 1060 4x8 sheet aluminum for sale is about 20 yuan/kg, that is, 20,000 yuan/ton. To calculate the price of a square 1mm thick 1060 aluminum sheet, it can be calculated by weight per square * unit price.
How much is a ton of 1mm 4x8 sheet aluminum for sale square?
Everyone must first know that the density of aluminum is 2.7. Therefore, how many squares is a ton of 1 mm aluminum sheet, and that is, 1/2.7/0.001 ≈370.
