5xxxserien

The 5xxx series refers to a group of aluminum alloys characterized by their primary alloying element being magnesium. These alloys offer a good combination of strength, corrosion resistance, and weldability, making them suitable for a variety of applications. The most common alloys within this series include 5005, 5052, 5083, and 5086.

Alloy 5052 is particularly popular due to its excellent corrosion resistance, especially in marine environments, and its good formability. It finds use in shipbuilding, automotive parts, and architectural applications. Alloy 5083 is known for its high strength and excellent weldability, making it a preferred choice for structural components in ships, cryogenic storage tanks, and pressure vessels. Alloy 5086 offers good strength and corrosion resistance, often used in marine applications and truck bodies. Alloy 5005, while having lower strength than others in the series, has good anodizing characteristics, making it suitable for decorative purposes and appliances.

The 5xxx series aluminum alloys are generally not heat-treatable, meaning their strength is achieved through strain hardening. This also contributes to their good ductility and formability. Their resistance to saltwater corrosion is a significant advantage, leading to their widespread use in marine and offshore industries. While they offer good strength, they do not reach the very high tensile strengths found in some other aluminum alloy series.
