The main materials of car fuel tanks are iron and aluminum alloy. In recent years, with the development of automobile lightweight trend, more and more automobile manufacturers choose aluminum alloy to manufacture car fuel tanks. 5052 aluminum and 5754 aluminum alloys are usually considered to be the aluminum alloys of choice for car fuel tanks. So can 3003 aluminum alloy be used in car fuel tanks? Yes, in addition to 5052 aluminum and 5754 aluminum, 3003 aluminum alloy is also a commonly used material of choice for car fuel tanks.
3003 aluminum belongs to the AL-Mn series alloy. It is a widely used rust-proof aluminum with excellent corrosion resistance, good welding performance, good formability, medium strength, and is cheaper than the 5 series aluminum alloy, so it is very suitable for use in car fuel tanks. In addition, 3003 aluminum is also commonly used in ships, vehicle materials, automobile and aircraft panel weldments, pressure vessels requiring strict fire protection, refrigeration units, television towers, drilling equipment, transportation equipment, passenger car skins, wide curtain wall panels, wide roof panels, etc.
Good corrosion resistance: 3003 aluminum alloy has good corrosion resistance to the atmosphere, seawater, organic acids, gasoline, neutral inorganic salt water solutions, etc., ensuring the safety of fuel use. Medium strength: The strength of 3003 aluminum alloy is 20% higher than that of 1 series aluminum alloy, and the strength can be further improved through cold working. Good weldability: 3003 aluminum alloy is not only highly weldable, but can also be fused to other aluminum alloys. It will not cause the weld to break or leak when subjected to strong impact. Light weight, meeting lightweight needs: Compared with traditional iron fuel tanks, aluminum alloy fuel tanks are much lighter and can save energy. The price of 3003 aluminum alloy is more advantageous than that of 5 series aluminum alloy, and it is especially suitable for small car fuel tanks.| Alloy | 3003 aluminum alloy |
