6000 Aluminum vs 7000- What’s the Difference

Aluminium 7000 series vs 6000

When it comes to aluminum, there are two main series that are widely used for different applications. The first is the 6000 series, which is composed of magnesium and silicon. On the other hand, the 7000 series is composed of zinc and magnesium. Both of these series have their own strengths and weaknesses when it comes to manufacturing, so let’s take a closer look at the differences between the aluminum 7000 and 6000 series.

Strength Factor

The aluminum 7000 series has higher strength than the 6000 series. This makes it ideal for applications where strength is a priority, such as aerospace engineering. It also has greater corrosion resistance due to its higher zinc content compared to the 6000 series, which has higher levels of magnesium. However, this also means that the 7000 series is more expensive than the 6000 series due to its added zinc content.

Heat Treatment Factor

The heat treatment process for the aluminium 7000 series takes longer than that of the 6000 series because it requires a longer time period for cooling after heating up. As a result, this increases production costs because it takes more time to finish each product with heat treatment applied to them. This could be seen as an advantage or disadvantage depending on your needs; if you need something quickly, then you may want to go with the faster option (6000). But if you’re looking for something tougher, then you may want to opt for the 7000 series since it’s more resistant to corrosion and tougher overall.

Weight Factor

Aluminium 7000 is heavier than its counterpart – making it unsuitable for use in places where weight matters, such as shipping containers or lightweight structures like bridges. On the other hand, aluminum 6000 can be thinner and lighter while still having good strength compared to most metals – making it suitable in applications where weight matters, such as aero planes or ships.


For those looking into using aluminum in their projects, understanding what sets aluminium 7000 apart from 6000 can make all the difference in deciding which one will work best for your needs. Depending on your application, either one could be better suited than the other, so make sure to do research into both before making a final decision! Ultimately both have their advantages and disadvantages but understanding these differences will help you make an informed decision when choosing between the aluminum 7000 vs 6000 series!
