Understanding Rolled Product Aluminium Grades and Aloys: 5005, 5052, 5251, 5083

Different grades of aluminium contain unique mechanical characteristics such as strength, corrosion resistance, and weldability. As a result, comprehending these differences will allow you to select the most suitable option for your projects, ensuring optimal performance and longevity. Whether it involves constructing small boats, vehicle and tip truck bodies, or architectural structures, identifying the most appropriate alloy ensures efficient utilisation of resources and enhanced performance.

Capral offers a range of aluminium alloys for rolled products, including 5005, 5052, 5251, and 5083, each with unique properties that cater to different applications. The 5000 series is alloyed with magnesium, making it corrosion-resistant but non-heat treatable. For example, 5005 has excellent weldability and good cold formability, widely used for silos and caravan sidings. Meanwhile, 5083 has excellent weldability and corrosion resistance, making it best suited for small boats and tread plates.

5005 is a medium-strength general-purpose alloy with good weldability, formability, and corrosion resistance. It is extremely popular and is the most commonly used grade of aluminium in sheet and plate form. It is suitable for decorative anodising and is often used in architectural applications.

5052 is a medium-strength alloy with excellent corrosion resistance, particularly in marine atmospheres. One of the more popular alloys, 5052, has good weldability. It is significantly stronger than 5005 alloy and is widely used in small boats.

5251 is a medium-strength, non-heat-treatable alloy often used as an alternative to 5052. It has excellent corrosion resistance and weldability. However, its lower magnesium content makes its mechanical properties slightly lower.

5083 is known for exceptional performance in extreme environments. 5083 is resistant to attack by seawater and general industrial environments. It has the highest strength of the non-heat treatable alloys but is not recommended for use in temperatures over 65 degrees.
