5182 Alloy Uses

Aluminum 5182 is used in a variety of industries due to its excellent properties. It is commonly used in transportation and automotive applications such as fuel tanks. It can also be used for chemical storage tanks due to its well-known corrosion-resistant properties. Additionally, it is often found in industrial machinery parts because of its high strength and machinability.

Corrosion Resistance

Aluminum 5182 is renowned for its corrosion resistance properties due to the presence of magnesium in its alloy composition. This alloy’s natural protective oxide layer makes it ideal for use in highly corrosive environments where stainless steel isn’t suitable. In addition to this natural protection against corrosion, aluminium 5182 can also be treated with anodizing or painting to further enhance its corrosion resistance capabilities.

Heat Resistance

aluminum 5182 has good heat resistance up to approximately 400°F (204°C). This makes it suitable for high-temperature applications such as exhaust systems or other components that may come into contact with hot air or liquids. Its heat resistance also means that it can be welded without compromising its mechanical properties or integrity when exposed to high temperatures over prolonged periods of time.

Heat Treatment

Aluminium 5182 can be heat treated using annealing processes which modify the material’s mechanical properties by changing the shape or size of the crystal grains within the metal structure. Annealing allows aluminium alloys like aluminum 5182 to gain increased strength while maintaining their formability and ductility characteristics which are important for many manufacturing processes, including welding and forming operations.


When machining aluminium alloys like aluminum 5182, it is important to utilize proper tooling methods due to their low cutting speeds compared to other metals like steel or stainless steel alloys. Utilizing specially designed tools specifically designed for machining aluminium will help reduce wear on your tools while increasing production rates and accuracy during your machining operations utilizing this material.


Welding techniques used on aluminum alloys like aluminium 5162 depend on the type of welding process utilized and any additional treatments required, such as anodizing or painting, after welding operations have been completed successfully. Some welding processes require special pre-heating steps prior to welding, while others require post-weld heat treatments after completion, which should be considered when selecting a welding process for this application-specific material type.


All things considered, aluminum five one eighty-two is a great choice for many types of fabrication projects requiring strong yet lightweight materials with excellent corrosion-resistant properties and good heat resistance capabilities when compared to other metals like steel alloys. With proper treatment before, during, and after fabrication processes, you will ensure success when working with aluminium five one eighty-two on your next project.
