In contrast to conventional 5083 alloy,  5383 alloy has significant outstanding characteristics in weight savings in aluminum vessels design, a minimum of 15% increase in the post-weld yield strength, improvement in corrosion properties, and a 10% increase in fatigue strength.

These improvements, along with equal key characteristics as 5083, made the explosion of 5383 alloys in shipbuilding both an opportunity & innovation for competitive manufacturers like PMI who pushing the limits for shipbuilder to design bigger & faster aluminum ships.

PMI continuously extends the 5383 alloy potential in #marine shipbuilding. Up to now, we have supplied an assortment of 5383 extruded components and assisted shipbuilder to float several ocean-going high-speed aluminum passenger ferries. With our higher performance fabrication, together with customer we achieve lighter weight ship with lower cost & never-compromise property.
