Custom Alloy Aluminum Ingot - Low Density, Heat-Resistant, For Aerospace Applications
Custom Alloy Aluminum Ingot is engineered for aerospace applications demanding lightweight durability and unmatched thermal stability. Utilizing 99.9% ultra-pure aluminum and advanced alloying elements like zirconium, lithium, and erbium, these ingots excel in environments exceeding 450°C, while maintaining a density of 2.65 g/cm³—20% lighter than conventional aerospace alloys. Certified to AMS 4121, ASTM E1251, and NADCAP AC7113, they are precision-cast into bespoke sizes (1kg–5,000kg) for use in spacecraft, hypersonic vehicles, and advanced propulsion systems.
Key Benefits:
- Ultra-Lightweight: Optimized for fuel efficiency and payload maximization in aerospace designs.
- Thermal Resilience: Retains structural integrity at 450°C+ with oxidation-resistant coatings.
- Custom Chemistry: Tailor Li (1.5–2.2%), Zr (0.08–0.15%), and Er (0.1–0.3%) for fatigue resistance.
- Aerospace Compliance: Meets MIL-STD-1530D, AS9100D, and ESA (European Space Agency) standards.
- Zero Defects: Electroslag remelting (ESR) ensures ultra-low porosity (<0.05%).
- Rapid Alloy Development: AI-driven metallurgical modeling for mission-specific performance.
