High Strength Marine Grade 5083 Aluminum Alloy Ship Hull Plate

High Strength Marine Grade 5083 Aluminum Alloy For Ship Hull Plate

5083 aluminum remains a top choice for ship hulls due to its marine-grade durability, weldability,

and lightweight properties.

Typical Thickness

♦ Thin plates: 3–6 mm (small boats, non-critical areas).

♦ Medium plates: 6–12 mm (most commercial vessels, yachts).

♦ Thick plates: 12–25 mm (large ships, high-stress zones like keels).

Typical Tempers

H116/H321:

H116: Optimized for stress corrosion resistance (ideal for marine environments).

H321: Stabilized after hot rolling, balances strength and corrosion resistance.

O (Annealed): Superior formability but lower strength; requires post-weld heat treatment.

Physical properties for 5083 aluminum alloy

Key Advantages

♦ Superior Cryogenic Performance:

Retains high toughness at liquid hydrogen (-253°C) and oxygen (-183°C) temperatures without

embrittlement.

♦ Fuel Compatibility:

Resistant to aviation fuels (e.g., RP-1), hydrazine, and oxidizers (e.g., LOX).

♦ Low-Temperature Toughness:

No brittle fracture risk in Arctic/polar applications.

♦ Weldability:

Compatible with TIG, laser, and friction stir welding (FSW), with weld joint efficiency ≥90%.

♦ Fatigue Resistance:

Low crack propagation rate under cyclic loading, ideal for reusable spacecraft (e.g., rockets).
