What Aluminum Alloys Are Best for Aerospace Die Casting?
Performance Requirements in Aerospace Casting
Aluminum die casting alloys used in aerospace must deliver an excellent strength-to-weight ratio, high dimensional stability, corrosion resistance, and reliable performance under mechanical and thermal stress. Aerospace components such as housings, brackets, and structural supports often require precise geometries, thin-wall capabilities, and resistance to fatigue and vibration. At Neway, our aluminum die casting services support a wide range of advanced alloys suited to meet stringent aerospace requirements.
Top Aluminum Alloys for Aerospace Die Casting
1. EN AC-43500 (AlSi10Mg)
EN AC-43500 is a high-performance aluminum-silicon-magnesium alloy known for its excellent mechanical strength, fatigue resistance, and weldability. Its fine microstructure and superior castability make it suitable for critical aerospace brackets and lightweight structural parts.
2. A356
A356 offers high strength after heat treatment (T6 temper), along with good corrosion resistance and elongation. It’s often used in aerospace wheel hubs, casings, and suspension components that demand both toughness and precision.
3. AlSi7Mg (EN AC-42100)
AlSi7Mg provides a good balance between strength, thermal conductivity, and corrosion resistance. It’s commonly selected for aerospace enclosures and heat-dissipating parts.
4. AlZn10Si8Mg (High-Strength Zinc-Aluminum Alloy)
AlZn10Si8Mg combines high mechanical strength with wear resistance and low thermal expansion. This alloy performs well in aerospace components subjected to fluctuating loads and extreme conditions.
5. A360
A360 is preferred for parts requiring excellent corrosion resistance and pressure tightness. It’s often used in aerospace hydraulic housings and electronic covers exposed to corrosive environments.
