When choosing the right type of metal for your project, countless options are available. But two of the most popular choices are 2014 Aluminium and 7075 Aluminium. Both are known for being strong, lightweight, and corrosion-resistant – but which one is right for you? In this blog post, we’ll take a closer look at the key differences between these two types of metal and help you make an informed decision.
What is 2014 Aluminium?
First of all, let’s take a closer look at 2014 Aluminium. This type of aluminium is an alloy of copper, magnesium, and silicon. It is a popular choice for applications that require good strength and high toughness, such as aircraft fittings and structural components. One of the main benefits of 2014 Aluminium is its high tensile strength, around 450 MPa. This makes it an excellent choice for projects that need to withstand a lot of stress or pressure.
What is 7075 Aluminium?
On the other hand, 7075 Aluminium is an alloy made up of zinc, magnesium, and copper. It is known for its high strength-to-weight ratio and excellent fatigue resistance. Many aerospace and defence applications use 7075 Aluminium because it can withstand highly stressful environments, such as extreme temperatures and high-altitude conditions. It has a tensile strength of around 572 MPa and is often used in rifle receivers and other high-stress applications.
Difference Between 2014 Aluminium and 7075
Cost
When it comes to cost, there is a slight difference between these two types of aluminium. 2014 Aluminium is often slightly cheaper than 7075 Aluminium because it contains less expensive metals. However, the cost difference is typically negligible unless you work on a large-scale project.
Corrosion Resistance
Another key difference is the level of corrosion resistance. 7075 Aluminium is more corrosion-resistant than 2014 Aluminium due to the higher amount of zinc in the alloy. This makes it a better choice for projects exposed to harsh environments, such as saltwater or acidic conditions. However, both types of aluminium are still highly resistant to corrosion compared to other metals, such as steel.
Ultimately, the choice between 2014 Aluminium and 7075 Aluminium depends on the specific requirements of your project. If you need a high-strength metal that can withstand extreme stress and fatigue, 7075 Aluminium may be the better choice. However, if your project requires good toughness and high tensile strength, 2014 Aluminium could be a more suitable option.
Conclusion
In conclusion, 2014 Aluminium and 7075 Aluminium are excellent choices for various projects due to their strength, lightweight, and corrosion resistance. While they have some similarities, they also have some key differences that must be considered before making a final decision. Ultimately, the choice between these two types of aluminium depends on the specific requirements of your project, so it’s important to consider all of the factors at play before making a decision.
