An aluminum alloy tanker manufactured by Chenglong Wei in Hubei Province was completed. Ordinary fuel tankers generally use carbon steel as the material to make tanks. This tanker is manufactured after the liberation of four tankers of eight tanks with advanced aluminum alloy materials. The cost of production will increase, but the functionality and advantages of this aluminum alloy tanker will increase infinitely. Aluminum is an early light metal material used in automobile manufacturing. It is also a relatively economical and practical light metal material for automotive use in structural materials. The proportion of aluminum is about 1/3 of that of steel, and aluminum alloys are recognized as the ideal material for lightweighting automobiles. From various perspectives, aluminum alloy tankers have the following advantages and characteristics: 1. Body weight can be reduced to improve tanker performance. The proportion of aluminum is about 1/3 of that of steel, and the aluminum alloy material has the characteristics of light weight, which can effectively reduce the body weight. 2. Can effectively reduce vehicle fuel consumption. Using aluminum alloy instead of traditional steel as the tank material can reduce the weight of the entire vehicle by 30% to 40%. Research shows that about 60% of the fuel used in automobiles is consumed in the weight of the automobile, and the mass of the vehicle body is reduced by 100 kg per kilometer. Fuel consumption will be reduced by 0.4 L to 0.8 L. Today, as oil prices have risen again and again, fuel economy is equal to saving money, and fuel-efficient vehicles have become a trend. 3. Compared with ordinary carbon steel tankers, aluminum alloy tank trucks have anti-corrosion function and can be loaded with corrosive materials. This is another major feature of aluminum alloy tank trucks. 4. Aluminum alloy tankers, environmentally friendly vehicles. The lightweight aluminum alloy tanker means that it reduces the fuel consumption and the amount of pollutants discharged from the vehicle. It also means that it is environmentally friendly. Because exhaust gas contains a lot of carbon dioxide, it is a major source of pollution to the environment. Therefore, the application of aluminum alloy materials for environmental protection Made a contribution.
