1. What is Aluminum-Silicon Alloy?

Aluminum-Silicon alloy is a kind of aluminum alloy, mainly composed of aluminum and silicon elements, and the silicon content is usually between 5% and 30%. It has excellent casting properties and good mechanical properties, so it is widely used in structural parts that require lightweight and good corrosion resistance.

Main Features And Advantages:

Lightweight: The density of aluminum-silicon alloy is about 2.7 g/cm³, which is about one-third of steel, so it can effectively reduce the weight of the whole vehicle when used in automobile manufacturing.

Good castability: Al-Si alloy has good fluidity and less tendency to thermal cracking during solidification, so it is suitable for castings with complex shapes.

High strength and wear resistance: The silicon content of Al-Si alloy makes it have high wear resistance and is suitable for automotive parts with high workloads.

Excellent corrosion resistance: Silicon alloy has good corrosion resistance to the atmosphere, seawater, and chemical media, and is particularly suitable for automotive engines and heat exchangers.

Good thermal conductivity: Aluminum-silicon alloy has high thermal conductivity, which helps to improve the heat dissipation performance of heat source components such as engines, and improve the efficiency and reliability of engines.

2. The Role of Aluminum-Silicon Alloy In The Development of Lightweight Automobiles

Due to its excellent properties, aluminum-silicon alloy is widely used in many important parts of automobiles, especially in the die-casting process. The die-casting process can accurately control the shape and size of parts, reduce subsequent processing, improve production efficiency, and reduce manufacturing costs.
