Aluminium is one of the most widely used metals in the world, and for good reason. Its unique properties, including lightweight, corrosion resistance, malleability, and conductivity, make it an ideal choice for various applications across different industries. But not all aluminium is created equal, and when choosing between Aluminium 2007 and 7075, there are some key differences to consider. In this blog post, we’ll compare the two and help you understand which would best suit your needs.
Difference Between Aluminium 2007 and 7075
Chemical Composition:
The primary difference between the two is their chemical composition. Aluminium 2007 is an alloy containing copper as its main component and magnesium as a secondary element. 7075, on the other hand, is an aluminium alloy that contains zinc as its primary component, along with magnesium and copper. This difference in composition gives each alloy its unique properties and helps it fulfil specific needs.
Strength and Durability:
One of the key factors to consider when choosing between 2007 and 7075 is their strength and durability. Aluminium 7075 is a high-strength alloy often used in high-stress applications such as aerospace and defence industries. It has high yield and ultimate tensile strengths and is highly resistant to fatigue. Aluminium 2007, on the other hand, is not as strong as 7075 but is more durable and corrosion-resistant than 7075.
Machinability:
The machinability of both alloys also differs, with Aluminium 2007 being more machinable than 7075. This means it can be easily worked and shaped into different forms and is ideal for applications that require high precision and tight tolerance. However, 7075 is less machinable, and the machining process requires careful consideration and expertise to avoid defects and cracks.
Cost:
Cost is another factor to consider when choosing between the two alloys. Aluminium 7075 is a more expensive alloy due to its high strength, durability, and resistance to fatigue, making it suitable for high-stress applications. Aluminium 2007, on the other hand, is more affordable, making it a preferable choice for cost-sensitive industries.
Applications:
Choosing between the two alloys will largely depend on the application you have in mind. Aluminium 7075 is a popular choice for aircraft, aerospace, and defence industries due to its high strength and resistance. Aluminium 2007, on the other hand, is used in applications that require excellent corrosion resistance, such as marine and transportation industries.
Conclusion:
In conclusion, Aluminium 2007 and 7075 are excellent alloys with unique properties and benefits. Choosing between them will depend on your specific needs and application requirements. While 7075 is stronger and more durable, Aluminium 2007 offers better corrosion resistance and affordability. Whatever your needs are, it’s important to work with a reputable supplier who can help you make the right choice based on your requirements and budget.
