Aluminum World offers a range of alloys designed to meet the specific requirements of different industries. Understanding the differences between various alloys can help you make better choices for your project. In this blog, we’ll take a closer look at three common aluminum alloys: 2024, 7075, and 6063. By analyzing their characteristics and application methods, we will better help you select the alloy materials that best suit your project or manufacturing needs.

2024 Aluminum Alloy

Aluminum alloy is an alloy based on aluminum with a certain amount of other alloying elements added. It is one of the light metal materials. The more popular aluminum alloys include 7075, 2024, 6061 and 6063. 2024 aluminum alloy is a kind of high-strength hard aluminum and belongs to the Al-Cu-Mg series aluminum alloy. It has high strength and good cutting performance, and can be used for drilling, tapping and other operations. However, its corrosion resistance is poor, and its corrosion resistance can usually be enhanced by polishing, sandblasting or anodizing and other related treatments on its surface.

7075 Aluminum Alloy

7075 aluminum alloy is a cold-processed forged alloy with high strength, much better than mild steel. The main alloying element is zinc, which has good mechanical properties and anodic reaction. The fine grains of this aluminum alloy allow for better deep drilling performance and enhanced tool wear resistance. It has good plasticity after solution treatment, good heat treatment strengthening effect, good strength below 150 degrees, and particularly good low-temperature strength, poor welding performance, and tendency to stress corrosion cracking. Primarily used in aerospace and defense applications, it is the first choice when a lightweight yet durable material is required.

6063 Aluminum Alloy

The main alloying elements of 6063 aluminum alloy are magnesium and silicon. It has excellent weldability, extrusion and electroplating properties, good corrosion resistance, easy polishing and coloring film, and excellent anodizing effect. It is a typical extrusion alloy. It is widely used in building profiles, irrigation pipes, pipes, rods and profiles for vehicles, benches, furniture, lifts, fences, etc.

What are the differences in their chemical and physical properties?

Among these alloys, a key difference lies in their composition. 2024 contains mainly aluminum, copper and a small amount of manganese, while 7075 mainly contains aluminum, zinc and small amounts of copper, magnesium and chromium. 6063, on the other hand, is primarily composed of aluminum, magnesium, and silicon. These compositional changes result in significant differences in strength, corrosion resistance, and weldability between alloys.

From the perspective of physical properties, both 2024 and 7075 are known for their high strength, but the latter is stronger than the former. However, 7075 is more susceptible to stress corrosion cracking. 6063 is an extruded alloy with excellent formability, making it a popular choice for complex shapes and profiles. In addition, 6063 has a good surface finish and is well suited for anodizing, offering a wide range of aesthetic options.

Application areas:

2024 aluminum alloy is widely used in the aerospace industry, aircraft structures (skin, frame, ribs, bulkheads, etc.), rivets, missile components, truck wheels, propeller components and other various structural parts. It is used in a wide range of applications because of its high strength, hardness, and good plasticity and cutting properties.

7075 aluminum alloy is primarily used in aerospace applications such as aircraft parts and gears due to its impressive strength-to-weight ratio. In addition, it can also be used for high-stress structural parts, blow molding (bottle) molds, ultrasonic plastic welding molds, golf heads, shoe molds, paper molds, mechanical equipment, mold processing, and used to make high-end aluminum alloy bicycle frames.

In contrast, 6063 is popular in architectural applications such as window frames, door frames and curtain walls, where its extrudability and good surface finish help create visually appealing designs. In addition, it is also used in various aluminum frames, aluminum radiators, electronic and electrical equipment and other fields.

Overall, knowing the differences between aluminum alloys 2024, 7075, and 6063 will allow you to make a more informed choice when selecting the right alloy for your project. Each alloy has its own unique chemical and physical properties, as well as different areas of application. By carefully considering these factors, you can ensure that you make the right choice and achieve the desired results on your aluminum-based project. You can also come to consult us.
