■ Product Advantages

Strengths of 5083‑O/H112 Aluminum Tube

  • Premium‑level seawater and salt‑spray corrosion resistance for permanent offshore exposure

  • Dual‑temper flexibility: O temper delivers deep‑formability; H112 provides enhanced extruded structural strength

  • Outstanding weld performance with minimum strength loss after welding

  • High fatigue resistance under constant wave vibration and cyclic marine loads

  • Light‑weight construction cuts overall weight of offshore equipment without sacrificing rigidity


Applications of 5083‑O/H112 Aluminum Tube

  • Seawater circulation pipelines for vessels

  • Load‑bearing structural parts of offshore platforms

  • Corrosion‑resistant frameworks for coastal industrial facilities

  • Ship auxiliary piping systems

  • Offshore machinery components exposed to salt‑rich atmosphere
