At present, automobile lightweighting is a general trend. The lightweight design of automobiles adopts modern design methods and effective means to optimize the design of automotive products or use new materials. Under the premise of ensuring comprehensive performance indicators of automobiles, it can achieve weight reduction, energy saving and emission reduction. Comprehensive indicator of safety. To make the vehicle weight light, the aluminum alloy is a perfect material.

The chassis is the main frame of the vehicle’s underbody. The power section of all vehicles, including the engine, axles, gearbox, differential, etc., and suspension system are mounted on the chassis. The function of the chassis is to support and install the automobile engine and its various components and assemblies to form the overall shape of the car, and to receive the power of the engine to make the car move and ensure normal driving. At the same time, a good chassis can guarantee the safety of the driver’s life. 6061 aluminum sheet plate is a new material for processing automobile chassis.

The chassis of the car occupies a large part of the overall weight of the car. How to effectively reduce the weight of the car body while ensuring safety. The material of the car chassis has high performance requirements for the 6061 aluminum plate. Automotive lightweight has the following advantages: 1. Lightweight. All aluminum is at least 100kg lighter than conventional steel. Improve power, fuel economy, and control. 2. Corrosion resistance. The durability of use is higher than that of steel. 3. More secure. Aluminum absorbs twice as much energy as ordinary steel.
