What Aluminum Alloys Are Best Suited for Aerospace Die Casting?
A356 – High Strength and Fatigue Resistance
A356 is widely used in aerospace structural castings due to its excellent strength-to-weight ratio and fatigue resistance. With a tensile strength of up to 275 MPa after T6 heat treatment, A356 is ideal for structural parts such as brackets, housings, and support frames. Its fine-grain structure and low porosity also make it suitable for components requiring high reliability under cyclic loading.
AlSi10Mg – Precision and Weldability
AlSi10Mg (EN AC-43500) offers a balanced combination of castability, mechanical strength, and corrosion resistance, making it highly suitable for aerospace components exposed to complex environmental conditions. It achieves yield strengths of around 190 MPa and can be post-processed through welding, machining, or anodizing for protective coatings. Common applications include control housings, airframe fittings, and ventilation components.
AlZn10Si8Mg – Superior Strength at Elevated Temperatures
AlZn10Si8Mg is an advanced aluminum alloy for aerospace applications that demand elevated mechanical performance under thermal stress. With tensile strengths reaching 320 MPa and excellent dimensional stability, it is used for load-bearing and heat-exposed parts such as engine covers, gearbox housings, and heat shields.
A360 – Excellent Corrosion Resistance and Fluid Tightness
A360 offers superior corrosion resistance and pressure tightness compared to A380, making it a good candidate for fuel system components, hydraulic housings, and environmental sealing enclosures. Its castability also supports the integration of fine features and wall thicknesses down to 2.5 mm, helping reduce overall part weight—critical in aerospace design.
