- 6061 aluminum is a flexible alloy that can be heat-treated. It is often used for general structural purposes.
Choose 5454 Aluminum if you want good resistance to corrosion in tough places. Pick 5052 Aluminum if you need something that forms easily. Go for 5083 Aluminum if you need the strongest type. Use 6061 Aluminum when you want a flexible choice for everyday structures.
Quick Overview of Aluminum Tempers
What Are Aluminum Tempers?
Aluminum tempers such as H32, H34, and O indicate the heat treatment and mechanical methods applied to an aluminum alloy. These tempers influence its strength, hardness, formability, and several other qualities.
These tempers play an essential role in the Aluminum Association’s way of naming temper! A letter (like H or O) indicates the type of treatment. The following numbers (like 32 or 34) explain the specific process used. I am excited about the H32, H34, and O tempers. We will explore how they are different and where they can be applied. Together, we will discover how these tempers can influence the performance of aluminum alloys, such as 5454!
The Common Tempers of Aluminum
H Temper (Strain-Hardened): The “H” label shows that the aluminum is stronger because it has undergone strain-hardening methods. These methods include cold working, like rolling or drawing. The extra numbers tell us more about how much it has been hardened and whether it has received any heat treatments for stability.
- First digit (like H3): This shows strain hardening and heat treatment done.
- Second digit (like 2 or 4): This tells us the hardness of the material. A higher number means the material is more rigid (for example, 4 is tougher than 2).
O Temper (Annealed): The “O” in O Temper means the aluminum has been fully annealed. This process involves heating the aluminum and then cooling it slowly. It helps to remove any internal stresses, making the aluminum very soft and easy to shape.

How to Choose Between H32, H34, and O Tempers
- Choose H32 if you want a good balance of strength, formability, and corrosion resistance. This is great for things like pressure vessels or marine structures. It works well where you need moderate forming and durability. For instance, use 5454-H32 in high temperatures for marine use.
- Choose H34 when you need more strength and hardness. This is good for heavy-duty marine or industrial parts but still needs some formability. A good example is 5083-H34, which is used in shipbuilding.
- Choose O if you need the best formability. This is important for deep-drawn parts or complex shapes, where strength isn’t as important. A good case would be 5052-O, which is used for fuel tanks.
