From aerospace engineering and construction to medical implants for repairing injuries, aluminium 2097 is a key element in innumerable technological innovations. Its ability to retain its shape when exposed to high temperatures means it is also ideal for vehicle parts, kitchenware, and cookware. Such versatility of cement aluminium 2097 is one of the go-to elements for manufacturers worldwide.

Corrosion Resistance

The addition of copper makes aluminium alloy 2097 highly resistant to corrosion. This means that parts made from this material can be used in outdoor environments without fear of rusting or corroding over time. Its low density also helps reduce the risk of corrosion as it makes the parts less likely to accumulate moisture or build up deposits.

Heat Resistance

Aluminium alloy 2097 has very good heat resistance, which allows it to withstand temperatures up to 200°C before experiencing any permanent deformation or loss of strength. This makes it suitable for use in high-temperature applications such as automotive components, aircraft components, heat exchangers and more.

Heat Treatment

To further increase its strength properties, aluminium alloy 2097 can be subjected to various heat treatments such as annealing or solution heat treatment. These processes allow the metal’s crystalline structure to become more organized, which increases its hardness and tensile strength while maintaining its ductility.


Aluminium alloy 2097 can be machined easily using conventional tools such as drills and taps, but extra caution should always be taken when machining this material due to its soft nature. It is also important to use cutting fluids when machining this material to minimize tool wear and improve surface finish quality.


Aluminium alloy 2097 can easily be welded using gas tungsten arc welding (GTAW) or shielded metal arc welding (SMAW) techniques, but extra care must be taken when selecting the right filler rod or wire for the job due to its tendency to crack during welding if not done properly. AWS ER4043 should be used for best results when welding this material together since it has been specifically designed for welding aluminium alloys like this one.


As you can see, aluminium alloy 2097 is an extremely versatile material with many beneficial properties which make it suitable for a wide range of applications, including automotive components, aircraft components, heat exchangers etc. Thanks to its excellent corrosion resistance and good heat resistance properties coupled with ease of machinability and weldability, it’s no wonder why so many engineers rely on aluminium alloy 2097 for their projects!
