The 5000 series aluminum (Al-Mg alloys) are non-heat-treatable wrought alloys strengthened by cold working (strain hardening). These alloys combine excellent corrosion resistance, particularly in marine and humid environments, with good weldability, moderate strength, and good ductility.
Common alloys in this series include 5052, 5083, 5005, 5754, 5083, which find extensive use in shipbuilding, vehicle bodies, pressure vessels, architecture, and storage tanks.
YUQI Metal offers 5000 series aluminum in forms of coils, sheets, and plates, supporting custom thickness, width, temper, surface finish (anodized, painted, embossed), and cutting/fabrication.

A1: The high magnesium content gives it superior corrosion resistance, especially against saltwater attack, making it ideal for ship, offshore, and coastal structures.
A2: No. They are non-heat-treatable alloys. Strength must be achieved through cold working (strain hardening) rather than thermal processes.
A3: 5052 is very common for its balance of formability and corrosion resistance. 5083 and 5086 are marine-grade for high corrosion and structural requirements. 5005 is often used in decorative architecture.
A4: Yes. We support custom widths/lengths, cutting, embossing/patterning, anodizing or coating, bending and fabrication per project needs.
A5: High magnesium content 5000 series alloys can weaken in prolonged exposure to elevated temperatures (above ~100–150 °C), and may be susceptible to stress corrosion at higher temperatures.
