Aluminium Grade 6061 for Car Body

The aluminum alloy for car body has become the most potential market for lightweight cars. The types of alloys involved in car body panels include 6016, 6022, 6111, 6181, 5754, 5182 and 5052. Among them, the inner body panels are basically made of 5182 alloy and 6181A alloy, while the outer body panels are mainly made of 6016, 6111 and 6022 alloys.

Aluminum alloys for automobiles are mainly divided into cast aluminum alloys and deformed aluminum alloys. Cast aluminum alloys are mainly used in engine cylinder blocks, cylinder heads, wheel hubs, brake parts, etc. Deformed aluminum alloys are mainly used for body panels, body frames, and engine radiator parts in automobiles.

Aluminum grade 6061 is often used to make automobile wheels. Since the car models are various, the diameters of the corresponding wheel hubs are also different. The cars can be generally divided into passenger cars and commercial vehicles. Among them, a passenger car refers to a vehicle with less than nine seats (including the driver's seat) whose main purpose is to carry passengers. Commercial vehicles refer to vehicles with more than nine seats (including the driver's seat) or with the main purpose of carrying goods.

For the 6061 aluminum sheet, the Mg2Si strengthened phase formed by its Mg and Si elements can significantly improve its mechanical properties. The 6061 alloy ingot can be homogenized at 565℃/4h-6h to make most of the Mg and Si solid-dissolved in aluminum, which not only reduces the forging temperature, but also improves the forging performance.

After special treatment (T6), 6061 alloy reaches medium strength, which is higher than 5 series alloys. Moderate strength is ideal for industry. Fenders ,hood outer panel and doors can be all made of 6061 aluminum plate. Welcome to leave message to inquire our 6xxx and 5xxx automobile cars.
