How to Identify Different Grades of Aluminium

Aluminium is an incredibly versatile material used in a wide variety of industries and applications. Different aluminium grades are suitable for other uses and purposes, so it’s important to understand the differences between them. This blog post will provide an overview of how to identify the different grades of aluminum.

Aluminum grades can be identified by two main criteria – alloy composition and temper designation. The alloy composition is usually shown as a four-digit number that identifies the major alloying elements present in the material. For example, “6061” would indicate that aluminum contains magnesium, silicon, and some other minor elements. The temper designation is usually presented as a letter code (e.g., T4 or T6). This indicates how strong the material is and how it has been treated during manufacturing.

Understanding these two factors is essential in order to correctly identify aluminum grades. It’s also important to consider other factors, such as formability, machinability, and weldability, when choosing which grade is best suited for your particular application. Some common grades include 1050A (99% pure), 3003 (for general-purpose use), and 6061-T6 (for high-strength applications).

In addition to understanding the alloy composition and temper designation, you should also familiarize yourself with other specifications related to aluminum grades, such as tensile strength, ultimate shear strength, elongation at break point, etc. These are all important factors to consider when selecting a grade for your project or product.


Aluminium is one of the most commonly used materials in modern life due to its versatility, durability, and affordability. When selecting an aluminum grade for a specific application or product, it’s important to understand how to identify different aluminium grades based on their alloy composition and temper designations. Knowing these key factors will help you choose the right grade for your project or product needs while also considering other specifications, such as tensile strength or ultimate shear strength that may apply in your particular situation.
