Aluminum alloys have a series of excellent characteristics such as low density, high specific strength and specific stiffness, good elasticity, good impact resistance, and relatively high recycling rate and recycling rate, so they have received widespread attention. The density of aluminum alloy is low, only 2.7g/cm3, and the density of aluminum is only 1/3 of that of steel or iron. It can effectively reduce the weight of the vehicle itself when used in automobiles.

At present, the aluminum alloys used for automobile body panels mainly include 2000 series, 5000 series and 6000 series alloys. The 2000 series alloy belongs to the Al-Cu-Mg series and is an aluminum alloy that can be strengthened by heat treatment. It has excellent forgeability, high strength and good weldability. The strengthening phase is CuMgAl2 and CuAl2. Mg in the 5000 series alloy It is the main alloying element, which is dissolved in the aluminum matrix to form a solid solution strengthening effect. It is an aluminum alloy that cannot be strengthened by heat treatment. The main alloying elements in the 6000 series alloys are Mg and Si, which form the Mg2Si phase, which belongs to the heat treatment-strengthened aluminum alloy. Al-Mg-Si alloy has high strength, good plasticity and excellent corrosion resistance. Compared with the steel plate, the yield strength and tensile strength of the 6000 series-T4 plate are similar, and the value of the hardening coefficient n even exceeds that of the steel plate. This kind of aluminum alloy profile with complex cross-sectional shape not only has the characteristics of light weight, high strength and good impact resistance, but also has good extrusion forming performance and is easy to manufacture, so it will be widely used in automobiles.
Commonly used aluminum alloys for aluminum alloy tankers include 5000 series magnesium aluminum alloy and 6000 series aluminum magnesium silicon alloy. 5000 series magnesium-aluminum alloy is mainly used as tank material, and 6000 series aluminum-magnesium-silicon alloy is often used for other accessories and frame. The design of the frame diagonal supports, longitudinal beams, and beams fully considers the different stress values of each part during driving, and carries out targeted design and optimization plans for each part. Under the premise of meeting the driving requirements of various road conditions of the vehicle, the The whole vehicle is lighter and bears better force.
The single vehicle price of aluminum alloy tank truck is higher than that of carbon steel structure tank truck, but after the scale effect is realized, the total investment in equipment has dropped significantly. Taking a semi-tank as an example, the price of an aluminum alloy semi-tank is about 100,000 yuan higher than that of a carbon steel semi-tank. Compared with the carbon steel structure tanker, the vehicle load capacity is increased by 7 tons. Under the condition that the total vehicle ton remains unchanged, the on-board quality of every 4 aluminum alloy semi-trailers is equivalent to that of 5 carbon steel semi-trailers. The cost of purchasing 4 aluminum alloy semi-trailers is 400,000 more than that of purchasing 4 carbon steel structure semi-tanks, but if the total vehicle ton remains unchanged, one more carbon steel structure semi-tank (including tractor) is purchased, and the price (including purchase) Taxes, etc.) in the range of 600,000 to 650,000 yuan. The cost savings are obvious.
Due to the light weight of the top of the aluminum alloy tanker, the center of gravity of the whole vehicle is low, and it is not easy to roll over, which enhances driving safety; the aluminum alloy material has good electrical conductivity, and static electricity is not easy to accumulate, which reduces the possibility of vehicle flash explosion accidents; It has good corrosion resistance and can form a dense aluminum oxide coating on its surface to prevent the erosion of atmosphere and moisture. After rubbing, the surface will automatically regenerate an oxide film to ensure the service life of the vehicle; since the aluminum alloy will not rust, it eliminates the possibility that the bottom of the oil will react with the tank due to water content and pollute the oil; the environmental protection performance of the aluminum alloy Well, aluminum alloys are recyclable, and when the virgin metal is replaced with aluminum alloy scrap, the recycling rate can reach 95%.
