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%
