What Is Aluminum Alloy?

This is an aluminum alloy that was produced in Japan in 1935. Initially, it was a popular choice for manufacturing military aircraft, but its application has expanded significantly, and today it can be found in a variety of products such as bicycles and rock climbing equipment.
 
While 7075 is primarily made of aluminum, it is an alloy, which means it contains a variety of other elements. Among its ingredients are silicon, copper, magnesium, tin, and manganese (which we’ll cover in more detail later). Due to the unique way its structure is formed, 7075 aluminum alloy has modified properties, exhibiting excellent strength and durability.
 

Composition

Here’s the breakdown of 7075’s composition:

  • Aluminum: 87.1–91.4% 
  • Zinc: 5.1–6.1%
  • Copper: 1.2–2.0%
  • Manganese: 0.0–0.3%
  • Silicon: 0.0–0.4%
  • Iron: 0–0.5%
  • Magnesium: 2.1–2.9% 
  • Chromium: 0.18–2.0%
  • Titanium: 0–0.2%
  • Other elements: 0.05–0.15%

Properties and Characteristics

If you want to understand how 7075 compares to other aluminum alloys, you'll find that it has high strength, moderate corrosion resistance, and relatively poor weldability. Its high zinc and chromium content also gives it good ductility and toughness. The following table shows several variations of 7075 and how their properties compare:
Variant Strength Corrosion Resistance Weldability Ductility
7075-O Low Medium Good High
7075-T6 High Average Poor Medium
7075-T73 High Good Poor High
These properties make 7075 aluminum alloy popular in demanding applications such as aerospace.
 
Choosing an Aluminum Grade

When you are weighing the different aluminum grades, there are several factors to consider that will help you choose the best aluminum for the job:
 
1. Strength: Consider, can your design accommodate the volume of material needed to achieve the strength level you’re after?
2. Fatigue resistance: There are more fatigue-resistant aluminum grades than others, but there are also materials that are more fatigue-resistant in general than aluminum as a whole. Understand the grade you need, and start there.
3. Machining: Not every alloy can handle all types of machining methods, so be sure to check that the grade you choose can handle forging and other processes.
4. Structure: If you plan on building or assembling parts, be aware that some grades of aluminum alloy are not suitable for welding (other grades are better).
5. Corrosion: Some aluminum grades have poor corrosion resistance, while others are quite resistant and can withstand long-term exposure to moisture and corrosive environments.
6. Damage resilience: Some aluminum profiles have a higher elongation at the breaking point than others, which is critical for life-critical structures
7.Cosmetics: If aesthetics are important, take a look at the quality of surface finish you can get with different grades.
