7000 Series Aluminium vs. 6061 Aluminum

When it comes to aluminium, there are many different types and grades available. Two of the most popular types are 7000 series aluminium and 6061 aluminum. If you’re trying to decide which type is the best for your project, you may want to consider the differences between these two materials. Let’s take a look at how they compare in terms of properties, applications, and cost.



Difference Between 7000 Series Aluminium and 6061 Aluminum


First, let’s start with an overview of the two types of aluminum and their properties. 7000 series aluminium is an alloy that contains zinc and magnesium as its primary alloying elements. It is also known for its strength, durability, and corrosion resistance. On the other hand, 6061 aluminum is an alloy with magnesium and silicon as its primary alloying elements. This type of aluminium is known for its excellent machinability and weldability, as well as its good strength-to-weight ratio.

When comparing these two types of aluminum side-by-side, it’s important to note that 7000 series aluminium tends to be stronger than 6061 aluminum. Still, it is also more expensive due to its higher zinc content. Additionally, 7000 series aluminium tends to be more difficult to machine than 6061 because it has a higher melting point and lower ductility than 6061 does.


In terms of applications, both types of aluminum can be used in various ways depending on what you need them for. For instance, 7000 series aluminium is often used in high-stress applications such as aerospace components or heavy-duty construction projects. In contrast, 6061 is commonly used in light structures such as bike frames or furniture components because it has improved machinability compared to other alloys like 7075 or 2024.

Cost Comparison

Regarding cost comparison between these two types of metals, it really depends on where you purchase them from and what grade you need for your project since prices can vary greatly depending on those factors. Generally speaking, though, the 6000 series will be less expensive due to its lower zinc content. In comparison, the 7000 series will be more expensive per pound due to its higher zinc content costs associated with manufacturing this type of metal alloy.




At the end of the day, both 6000 series aluminium and 7000 series aluminium have their unique pros and cons, so choosing between them will ultimately depend on what type of application you need them for as well as how much budget you have available for your project since prices can vary significantly from one supplier to another. Keeping all these points in mind when deciding will help ensure that you get the best quality materials at the right price point for your needs!

Overall, when deciding between using either 7001 or 6001 aluminium for your next project, consider all factors, including cost efficiency , strength requirements , machinability , corrosion resistance, etc., before making any final decisions!
