Alloy Aluminum Ingot Supplier - Precision-Engineered, Custom Compositions, MIL-Spec
As a trusted MIL-Spec alloy aluminum ingot supplier, we deliver precision-engineered solutions for mission-critical defense, aerospace, and industrial applications. Our ingots are smelted from 99.8% ultra-pure aluminum and fortified with tailored alloying elements (e.g., zinc, magnesium, scandium) to achieve unmatched strength, fatigue resistance, and thermal stability. Fully compliant with MIL-DTL-45220, AMS 4117, and ASTM B209, they are available in custom compositions and sizes (0.5kg–10,000kg) to meet exacting military and commercial specifications.
Key Benefits:
- MIL-Spec Compliance: Certified for defense projects requiring ITAR, DFARS, and NATO standards.
- Custom Alloy Blending: Optimize Zn (5.0–7.0%), Mg (2.1–3.0%), or Sc (0.1–0.3%) for extreme environments.
- Precision Engineering: Tolerances as tight as ±0.02mm for aerospace-grade machining.
- High-Temp Resistance: Stable up to 400°C with oxidation-resistant coatings.
- Zero Defects: Ultrasonic testing and vacuum-arc remelting (VAR) for flawless microstructures.
- Sustainable Production: 70% recycled content, ISO 14001-certified eco-friendly processes.
