Aluminium 6082 vs 7075 – What’s the Difference

Aluminium 6082 vs 7075

When looking for a strong, lightweight material that can be used in a wide variety of applications, aluminium is often the top choice. But with so many different types of aluminum available, it can be tough to decide which one is best suited for your project. Two types of aluminum that are commonly chosen are 6082 and 7075. Let’s take a look at what makes them different and why you might choose one over the other.

What Is Aluminium 6082?

Aluminium 6082 is an alloy made up mostly of aluminum and manganese alloyed with a small amount of magnesium, silicon and chromium. Because it has such low density—just 2.7 g/cm3—it’s often used in projects where weight needs to be kept to a minimum, but strength is still required, such as car bodies or railway carriages. It’s also resistant to corrosion and weld able, making it ideal for outdoor projects like bridges or frames for outdoor furniture.Aluminium 6082 also has good machinability properties; however, it does not have the same level of strength as some other alloys like 7075. This means that if you need something that is strong enough to withstand high-stress loads, then 6082 may not be the best option.
 

 

What Is Aluminium 7075?

Aluminium 7075 is another popular aluminum alloy that is known for its strength-to-weight ratio; this alloy contains zinc as its primary alloying element, along with small amounts of magnesium, copper and chromium added for increased strength and durability. As a result, this alloy has excellent fatigue strength as well as good resistance to wear and tear from impact or abrasion. Additionally, this alloy has good machinability properties despite its high strength level; however, because it contains more copper than other alloys like 6061 or 2024, it tends to be more expensive than those options.Aluminium 7075 is an alloy that is primarily composed of aluminium, zinc and magnesium. It is known for being one of the strongest aluminium alloys, making it a popular choice for applications where strength is required. Aluminium 7075 also has good resistance to corrosion.
 

 

Difference between Aluminium 6082 and 7075

Composition

One of the main differences between aluminium 6082 and 7075 is their composition. Aluminium 6082 contains more silicon than 7075, while 7075 contains more zinc. This difference in composition gives each alloy different properties.

Strength

One of the most notable differences between 6082 and 7075 is their strength. Aluminium 6082 is stronger than 7075 in tension, while 7075 is stronger in compression. This difference is due to the different compositions of each alloy.

Uses

Due to their different properties, aluminium 6082 and 7075 are used in different applications. Aluminium 6082 is commonly used in structural applications, while 7075 is commonly used in aerospace applications.

Price

Another difference between these two alloys is their price. Aluminium 6082 price per kg is typically cheaper than 7075 due to its lower zinc content.

Conclusion:

When choosing between aluminum alloys 6082 and 7075, there are several factors that should be considered before deciding which one will work best for your project or application. Aluminum 6082 offers excellent corrosion resistance combined with low density, while 7075 offers a superior strength-to-weight ratio but comes at a higher cost due to its higher copper content compared to other similar alloys. Ultimately the decision should come down to what type of performance you need from your product and how much you’re willing to spend on materials costs in order to get it!
