Implementation Standards

When implementing aluminum alloys in marine conditions, awareness of specific marine set industry standards is crucial. Common standards include:

• ASTM B209 (Aluminum Alloy Sheet and Plate)
• AWS D1.2 (Aluminum Welding)
• SAE AMS 4045 (Stability of Solid, Saddle helical in Corrosive Extrusions)
