As one of the most common types of metal used in manufacturing, Aluminium has become a critical component in numerous industries, from aerospace to automotive. However, with so many different aluminium alloys available, it’s important to understand their properties to select the right one for your project. In this blog post, we will compare two popular alloys, Aluminium 2007 and Aluminium 7075, to help you make an informed decision.
Difference Between Aluminium 2007 and 7075
Composition
Aluminium 2007 and 7075 both contain Aluminium, but they have different compositions. Aluminium 2007 contains 99.7% aluminium, while 7075 contains 99.0% aluminium. Aluminium 2007 contains 0.3% copper, while 7075 contains 5.8% zinc.
Strength
Aluminium 2007 is a soft metal, while 7075 is much harder. This difference in hardness is due to the different compositions of the two metals. Aluminium 2007 is primarily composed of Aluminium, while 7075 is a mix of Aluminium and zinc. Zinc makes 7075 much harder than Aluminium 2007.
Uses
Aluminium 2007 is typically used for applications that require high ductility, such as electrical conductor applications. 7075 is typically used for applications that require high strength, such as aircraft parts.
Cost
Aluminium 2007 is typically cheaper than 7075 due to the lower cost of Aluminium relative to zinc. However, the price difference between the two metals will vary depending on the current market prices of Aluminium and zinc.
Corrosion Resistance
Aluminium 2007 has good corrosion resistance due to the presence of copper in its composition. Copper forms a protective oxide layer on the surface of the metal that prevents further corrosion. 7075 does not contain copper and therefore does not have the same level of corrosion resistance as Aluminium 2007.
Conclusion
To sum up, Aluminium 2007 and 7075 are excellent alloys with unique properties that make them best suited for particular applications. Aluminium 7075 is stronger but more difficult to machine, has higher density and is more expensive. Meanwhile, Aluminium 2007 offers excellent machinability and is cheaper but with lower overall strength. Ultimately, the decision between the two alloys should depend on the specific requirements of your project. However, with this information, you are now better equipped to decide which of the alloys is best suited for your project.
