5251 aluminum sheet is a medium-strength aluminum-magnesium alloy with good ductility, formability, and weldability. As a material that cannot be heat-treated for strengthening, it mainly increases its strength through cold working, making it suitable for stamping, bending, spinning, and other processes. Its lightweight and high plasticity make it widely used in various commercial fields, such as container manufacturing, mechanical parts, and architectural decoration.
In addition, the 5251 aluminum sheet has excellent corrosion resistance, especially suitable for marine environments. Similar to the 5052 alloy, it is commonly used in hull structures, offshore platforms, and coastal equipment. This alloy also has good thermal conductivity and fatigue resistance, making it an ideal material for applications that require a balance of strength, lightweight, and durability, such as in ships, energy systems, and transportation equipment.
