Aluminum Alloy The common features of this type of metal are low density, high chemical activity, and very stable compounds with oxygen, sulfur, carbon and halogens. Among them, aluminum and aluminum alloys are the most widely used in industry. At present, its output has exceeded 1% of the total output of non-ferrous metal materials.
The main alloying elements in the series of aluminum alloys represented by aluminum bits are magnesium and silicon, which have medium strength, good corrosion resistance, weldability, and good oxidation effect. It is widely used in various industrial structural parts that require certain strength and high corrosion resistance, such as manufacturing trucks, tower buildings, ships, trams, railway vehicles, furniture, etc.

Introduction
Heat treatment can strengthen the alloy and has good formability and can be Weldability, machinability and, at the same time, it has medium strength and can still maintain good operability after annealing. The main alloying elements of the alloy are magnesium and silicon, and form a phase. If it contains a certain amount of manganese and chromium, it can neutralize the bad effects of iron. Sometimes a small amount of copper or zinc is added to improve the strength of the alloy without significantly reducing its corrosion resistance. There is also a small amount of copper in the conductive material. , to offset the adverse effects of titanium and iron on conductivity, zirconium or titanium can refine the grains and control the recrystallized structure. In order to improve the machinability, lead and bismuth can be added. When solid dissolved in aluminum, the alloy has artificial age hardening properties.
It is the main alloy of the alloy. It is a high-quality aluminum alloy product produced by heat treatment and pre-stretching process. Although its strength cannot be compared with the series or series, it has many magnesium and silicon alloy properties and has excellent processing performance. , excellent welding characteristics and electroplating properties, good corrosion resistance, high toughness and no deformation after processing, dense material without defects and easy to polish, easy coloring film, excellent oxidation effect and other excellent features.
