5083 Alloy Characteristics

5083 aluminum alloy is renowned for exceptional performance in extreme environments, demonstrating high resistance to both seawater and chemical exposure.

Physical Properties

Property	Value
Density	2650 kg/m3
Melting Point	570°C
Modulus of Elasticity	72 GPa
Electrical Resistivity	0.58 x 10-6 Ω.m
Thermal Conductivity	121 W/m.K
Thermal Expansion	25 x 10-6/K

Typical Thickness Applications

Thin sheets (0.5-3 mm): Used for tank liners or secondary structures requiring high formability
Medium plates (3-8 mm): Main load-bearing structures or tank walls, balancing strength and weldability
Thick sections (8-15 mm): High-pressure fuel tanks or critical joint areas

Common Tempers

H116: Stress-corrosion-resistant, suitable for long-term fuel exposure
H321: Thermally stabilized, maintains post-weld properties for high-pressure tanks

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)
Lightweight: Density ~2.7 g/cm³ (1/3 of steel), reducing launch mass and improving payload efficiency
Weldability: Compatible with TIG, laser, and friction stir welding (FSW), with weld joint efficiency ≥90%
