What is An All-aluminum Body?

When it comes to the all-aluminum body of a car, the most well-known feature is its lightness. Besides the expensive top-of-the-line runs that use a lot of carbon fiber, car lightweight designs mostly rely on a large proportion of aluminum.

The concept of all-aluminum body refers to that the body structure part of the car is mainly made of aluminum alloy, not only does which allow for the existence of some non-aluminum parts, but aluminum is also present in the form of alloys.

In fact, aluminum alloy is not a certain kind of alloy, and there are many kinds of aluminum alloy. The internationally accepted rule is to distinguish aluminum alloy types with a four-digit and one-letter status code. For example, the 6063-T5 commonly used in the construction industry, whose first number is 1, which represents pure aluminum with a purity of more than 99%; the numbers 2-8 represent alloys of aluminum and copper, manganese, silicon, magnesium, magnesium and silicon, zinc and other elements, respectively; the number 9 is the standby group. The numbers that follow are used primarily for differentiation, so the specific logic is no longer repeated. In a word, each formula of aluminum alloy has a special label to correspond to specific characteristics.

Currently, series 5 and 6 are mainly used in the manufacture of automobile all-aluminum body, all of which are of low density, tensile strength, and good fatigue resistance. They have higher strength performance far below the weight of steel and are widely used in Audi's ASF all-aluminum body. In addition, the 2 series and 7 series also have a small number of applications. The copper and aluminum alloy of 2 series with high hardness can be used in somebody sheet metal parts; the 7 series is mainly used in aerospace and military industries, which are ultra-hard, corrosion-resistant and wear-resistant materials with an impressive price.
