5454 aluminum is an alloy in the wrought aluminum-magnesium family. It is primarily composed of aluminum, magnesium, and a small amount of manganese, which enhances its strength and corrosion resistance.

The 5454 aluminum alloy is often used in high-strength structural applications such as pressure vessels, marine applications, and welded structures. It has excellent resistance to corrosion and is well-suited for use in harsh environments. Additionally, this alloy has good formability and weldability properties.
