Introduction

Corrosion resistance casting aluminum alloys are new materials, which solve certain special problems of traditional casting aluminum alloy materials, and become a forging materials that are widely used in modern technology. Corrosion resistant casting aluminum alloys are mainly used in high level structures. They are mainly used in the fields such as aviation industry, aerospace industry and shipbuilding industry, and are also required in some non traditional applications. For example, they can be used in building structures, chemical industrial pipelines, molds, and so on.

Composition of Corrosion Resistant Casting Aluminum Alloys

Corrosion resistant casting aluminum alloys are mainly composed of Al-Si-Mg, Al-Si-Cu, Al-Cu-Mg, Al-Mg-Si, Al-Si-Mg+Lithium, Al-Cu-Mg+Lithium, etc. They are mainly aluminum-based alloys, containing trace amounts of iron and silicon. The silicon content is generally higher than that of ordinary casting aluminum alloys, so that the corrosion resistance of these alloys is stronger.

Properties of Corrosion Resistant Casting Aluminum Alloys

1. High corrosion resistance: Corrosion resistant casting aluminum alloys have higher corrosion resistance than ordinary casting aluminum alloys, so they can be used in corrosive environment.

2. High strength: Corrosion resistant casting aluminum alloys are higher than ordinary aluminum alloys in strength and hardness, which can reduce the requirements of surface hardening and heat treatment while keeping their good casting performance.

3. Good conductivity: Corrosion-resistant casting aluminum alloys maintain good contact resistance and thermal conductivity, so that they are more suitable for electric welding when manufacturing bulky articles.

4. Low cost: Casting aluminum alloys have good casting performance, which can improve the production efficiency and reduce the production cost.

Application of Corrosion Resistant Casting Aluminum Alloys

Corrosion resistant casting aluminum alloys are mainly used in the production of aircraft body parts and aircraft engines, ship hulls and ship engines, automotive and other industrial parts. They can also be used in some corrosion-resistant parts for oil and chemical pipelines. In addition, corrosion resistant casting aluminum alloys can be used to produce tools, particularly molds for product manufacturing.

Conclusion

Corrosion resistant casting aluminum alloys are a kind of aluminum alloy with high corrosion resistance and excellent application performance. This alloy has good strength, good thermal and electrical conductivity, and can also reduce the cost of many products. At present, corrosion resistant casting aluminum alloys are widely used in the fields of aviation and aerospace, ships, automobiles and many other industries, and have brought great development to the application field of aluminum alloy research and development.
