2197 Aluminium Mechanical Properties

The mechanical properties of Aluminium 2197 depend on its composition, but generally, it has a tensile strength of around 240 MPa (35 ksi) and a yield strength of around 230 MPa (33 ksi). It has an elongation at a break value between 10% and 12%. Additionally, it has a Brinell hardness between 50 HBW and 70 HBW, depending on its composition.

2197 Aluminium Physical Properties

Aluminium 2197 has a density of approximately 2.71 g/cm3, slightly higher than pure aluminium’s density at approximately 2.7 g/cm3. Its thermal conductivity ranges from 150 W/mK to 180 W/mK, while its electrical conductivity ranges from 25% IACS to 35% IACS depending on the alloy’s composition. Its melting point is between 545°C to 622°C, while its boiling point is approximately 2462°C. Furthermore, this alloy can be heat treated for additional strength if needed, although this should be done cautiously as too much heat treatment can reduce its ductility significantly.

2197 Aluminium Chemical Properties

Aluminium 2197 is an interesting material that has unique chemical properties. While it is similar to other aluminium alloys in its ability to be cast and machined, it also stands apart in its higher level of corrosion resistance and heat tolerance, making it particularly suited for industrial applications. Its extreme malleability makes it suitable for treatment at low temperatures without degradation so that it can be easily formed into many desired shapes. Its high electrical and thermal conductivity can be a great asset in sensitive vehicle components or electrical connectors. It’s no surprise that Aluminium 2197 is the preferred alloy among engineers worldwide.

2197 Aluminium Uses

The properties of this alloy make it very useful for many applications, including aerospace engineering, where it is often used for engine parts such as pistons, cylinders, connecting rods or crankcases, and aircraft frames due to its low weight yet high strength ratio. It is also commonly used in automotive applications such as wheels, body panels and exhaust systems because of its corrosion resistance. Finally, it can also be used in the military thanks to its excellent formability, which makes it ideal for creating gas masks or armoured vehicles.

2197 Aluminium Corrosion resistance

Aluminium 2197 is a structural grade aluminium that has been extremely well-received in the engineering community for its amazing finish, dependable strength, and impressive corrosion resistance. It is particularly suited for outdoor applications as it can withstand harsh environments with high wear and tear. The particles clustered closely on Aluminium 2197 also ensure that it stands up to frequent use, making it a reliable material for applications exposed to weather conditions such as rain, snow or extreme temperatures. Add to this the fact that this grade of aluminium is easily formable and resists stress-corrosion cracking; then it’s no wonder that engineers are increasingly looking towards the possibilities of using Aluminium 2197 in their designs.

2197 Aluminium Heat resistance

Thanks to its high heat resistance, aluminium alloy 2197 is popularly used in a range of modern industries. It can be used in the automotive and aerospace industry, as well as industrial applications where heat resistance plays an important role in product safety. In particular, the combination of strength, corrosion resistance, and heat resistance make aluminium 2197 a perfect choice for high-temperature applications like piping systems that carry hot liquids and motorsports vehicles like planes, boats, and cars. Not only does this alloy provide superior protection for equipment and components exposed to extreme temperatures, but it also offers superior overall performance with little risk of damage from oxidation or corrosion.

2197 Aluminium Heat treatment

Aluminium 2197 is known for excellent formability and machinability, used widely within the aerospace industry. Heat treatment of this alloy can be divided into two parts: solution heat treat and ageing treatment. In the solution heat treatment, Aluminium 2197 is heated up to above 925°C and water quenched, which allows the alloying elements to hold mostly in a supersaturated solid-solution state. After that, an ageing treatment takes place when it is held at 195°C until the plane strain creep properties of Aluminium 2197 reach their optimum strengths. Overall, by highly controlling heating and cooling rates during the heat treatment process, engineers can maximize these features of Aluminium 2197 for forming exceptional components in the aerospace industry.

2197 Aluminium Machining

Machining aluminium 2197 is an intricate process best handled by a qualified machinist with experience in this material. It requires a high degree of precision and accuracy to work with aluminium’s malleable yet brittle nature. A CNC machine is necessary for most machining tasks, as it allows for greater control over the creation of parts and components from raw stock. The ability to precisely control the machine also comes in handy when cutting intricate shapes and creating certain finishes, as both require special attention. To be successful when machining aluminium 2197, choose quality tools with sharp edges and use coolants to minimize heat buildup while operating the machine and to reduce stress on delicate components. By adopting these practices, you can ensure that your finished product meets all the requirements.

2197 Aluminium Welding

Aluminium 2197 welding is a specialized yet necessary process in many industrial applications. It requires heat to join two individual pieces of aluminium alloy together. It must be done with precision to ensure the strongest hold possible and minimize any potential safety risks that could occur otherwise. Whereas traditional welding processes use an electric arc to melt the metal, Aluminium 2197 Welding uses what is known as a “cold weld” process that uses pressure rather than heat. This creates strong bonds between even large parts without warping or loosening them over time. As such, it has become increasingly popular for various construction applications and more across the world.


All in all, aluminium 2199 is an incredibly versatile material that offers excellent formability while still providing good strength and corrosion resistance, making it suitable for various uses across various industries, including aerospace engineering, automotive manufacturing, appliance manufacturing and military applications, among others. This alloy can be machined thanks to its good machinability, making it even more versatile than other alloys with similar properties, such as steel or titanium. As such, aluminium 2917 should be considered when looking for materials with these characteristics since it offers several advantages over other materials while still being cost-effective compared to more expensive options like titanium alloys or carbon fibre composites.
