the Features of 5083 Alloy
5083 aluminum alloy is well known for their exceptional performance in the most extreme environment.
The alloy show high resistance to both seawater and chemical environments.
Physical properties for 5083 aluminum alloy
| Property | Value |
| Density | 2650 kg/m3 |
| Melting Point | 570°C |
| Modulus of Elasticity | 72 GPa |
| Electrical Resistivity | 0.58 x 10-6 Ω.m |

Typical Thickness
Spacecraft fuel tanks require a balance of lightweight design, strength, and leak-proof performance.
The commonly used thickness ranges for 5083 aluminum alloy are:
♦ 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/H321:
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%.
