10 Things You Need to Know About Rolled Aluminium Products

Rolled aluminium products are a commonly used material in today's industrial and manufacturing processes. They come in various forms such as plates, sheets, coils, and foils. The material is easy to work with, lightweight, durable, and corrosion-resistant, making it a popular choice for a range of applications.

However, there are certain things that you need to know about rolled aluminium products before you use them. In this article, we will cover the top 10 things that you need to keep in mind when using rolled aluminium products.

1. Aluminium Grades.

Various grades of aluminium are used to manufacture rolled aluminium products. Each grade has its chemical composition and mechanical properties, including its ability to withstand deformation and corrosion resistance. Grades such as 1050, 6061, and 7075 are commonly used for various applications.

2. Temper of Aluminium.

The temper of rolled aluminium products refers to its hardness, strength, and flexibility. The temper is achieved by heat treatment processes such as annealing, quenching, and tempering. Temper designations include O, H, and T, with H and T being the most commonly used.

3. Surface Finish.

Rolled aluminium products come in various surface finishes, from smooth to textured. The surface finish is an important consideration for applications where aesthetics are crucial, such as decorative cladding, signage, and architectural features.

4. Thickness Tolerance.

The thickness of rolled aluminium products is critical to their performance. The thickness tolerance is defined as the allowable deviation from the nominal thickness, and it can affect the strength, deformation, and formability of the product. It is essential to use products with a tight thickness tolerance to ensure consistent performance.

5. Width and Length Tolerance.

The width and length tolerances of rolled aluminium products should also be considered. The width tolerance refers to the allowable deviation from the nominal width, while the length tolerance refers to the allowable deviation from the nominal length. Tighter tolerances are recommended for applications where precise dimensional control is required.

6. Flatness.

Rolled aluminium products must be flat to be used in various applications. Flatness is defined as the deviation of the product's surface from a perfect plane, and it can impact the product's appearance, stability, and performance. It is crucial to use products with the desired flatness specifications.

7. Weldability.

Many applications require the welding of rolled aluminium products. The ability of the product to be welded depends on its chemical composition and mechanical properties. Some alloys can be easily welded, while others require special techniques and equipment.

8. Corrosion Resistance.

Rolled aluminium products are known for their excellent corrosion resistance. However, their resistance to corrosion varies depending on their chemical composition, surface finish, and environmental factors. Factors such as humidity, temperature, and pollutants can affect the product's corrosion resistance.

9. Workability.

Rolled aluminium products are easy to work with using conventional techniques such as cutting, bending, and forming. The ability of the product to be worked depends on its mechanical properties and thickness. Thicker products require more force to work, while thinner products may be prone to deformation.

10. Sustainability.

Rolled aluminium products are sustainable due to their recyclability, lightweight, and energy efficiency. Aluminium is 100% recyclable without losing its properties, and its lightweight reduces transportation costs and carbon emissions. Its energy efficiency also contributes to reducing greenhouse gas emissions.

In conclusion, rolled aluminium products are an essential material in modern-day manufacturing and industrial processes. Before using them, it is crucial to considering factors such as grades, temper, surface finish, thickness tolerance, width and length tolerance, flatness, weldability, corrosion resistance, workability, and sustainability to ensure their optimal performance and reliability.
