Ship development trend: energy saving,Aluminum for boat speed increase, cargo capacity, maneuverability, Aluminum for boat etc.; marine material development trend: weight reduction, corrosion resistance, strength; goal: higher speed,Aluminum for boat more load capacity, fuel economy, low maintenance, Recycling.
Aluminum alloy features light weight: the density is only 1/3 of steel;Aluminum for boat Corrosion resistance: excellent intergranular corrosion resistance, spalling corrosion resistance; good formability: good processing and formability;Aluminum for boat high specific strength: aluminum alloy (5083- H321/H116) specific strength (120) is higher than stainless steel SUS3041/2H (106);
Weldable: can be applied to various inert gas shielded welding (TIG/MIG) and friction stir welding (FSW). Production process: raw materials-melting-casting-soaking-machining-preheating-rolling-heat treatment-cutting head and tail-sawing. Alloy and corrosion, corrosion, welding, welding test (hardness),Aluminum for boat welding test (organization)
