Aluminium is one of the most popular materials used in the manufacturing industry. It has several remarkable properties, including lightweight, corrosion-resistant, and high strength-to-weight ratios. Two of the most common types of aluminium are 2007 and 2011. Both are widely used in various industries, but what is their difference? In this blog post, we will explore the characteristics of aluminium 2007 and 2011 and compare them to help you understand which one is best suited for your application needs.
Difference Between Aluminium 2007 and 2011
Chemical Composition:
One of the primary differences between aluminium 2007 and 2011 is their chemical composition. Aluminium 2007 contains zinc and copper, whereas Aluminium 2011 contains copper as its main alloying element. Aluminium 2011 also has a small quantity of magnesium, making it ideal for machining or cutting operations. On the other hand, aluminium 2007 is used in applications that require high strength and corrosion resistance.
Mechanical Properties:
Aluminium 2007 and 2011 also differ in their mechanical properties. Aluminium 2007 has better tensile strength, making it ideal for high-pressure applications. Aluminium 2011, on the other hand, has better machinability, which makes it perfect for manufacturing precision components. Additionally, aluminium 2011 has lower ductility than aluminium 2007, malleability, and higher fatigue strength.
Applications:
Aluminium 2007 and 2011 have various industrial applications. Due to its high strength, aluminium 2007 is often used in construction, automotive, and aerospace industries. Aluminium 2011 is commonly used in electronic hardware and other precision parts because of its superior machinability. It is also widely used to produce screw machine parts, fittings, bushings, and hydraulic valve bodies.
Surface Finishing:
Aluminium 2007 and 2011 have different surface finishing properties. Aluminium 2007 is more susceptible to pitting and corrosion, while aluminium 2011 is more resistant. To improve the corrosion resistance of aluminium 2007, you need to apply a protective coating such as anodizing or painting. Aluminium 2011 does not require a coating, making it ideal for components that will be in contact with corrosive environments.
Cost:
Another thing you must consider when choosing between aluminium 2007 and 2011 is their cost. The cost of aluminium in 2007 and 2011 varies depending on availability, market demand, and usage. However, generally speaking, aluminium in 2011 was less expensive than in 2007. If budget concerns your project, then consider Aluminium 2011.
Conclusion:
In conclusion, both aluminium 2007 and 2011 have their advantages and disadvantages. The choice between the two depends on your application needs. Aluminium 2007 is excellent in high-pressure and high-corrosion environments, while aluminium 2011 is best for applications that require precision machining and involve corrosive environments. These two types of aluminium have different chemical composition, mechanical properties, applications, surface finishing, and costs. Understanding their characteristics will help you choose the best type of aluminium suited for your project.
