ADC14
Material Introduction
ADC14 is a premium aluminum–silicon–copper casting alloy engineered for high-performance aluminum die casting applications requiring exceptional dimensional precision, excellent thin-wall castability, and strong mechanical performance. Compared to general-purpose alloys such as ADC10 or ADC12, ADC14 offers a more optimized balance of silicon and copper, enabling superior fluidity for intricate mold features, higher strength for load-bearing parts, and improved fatigue resistance for long-service-life components. When produced through Neway’s advanced tool and die making systems and controlled molten metal management, ADC14 consistently delivers stable results across large injection cycles, making it a reliable choice for automotive structural parts, electronic housings, and complex precision mechanisms.
Alternative Material Options
If ADC14’s specific balance of performance and castability does not fully align with project goals, several high-quality alternatives are available. For superior fluidity, better corrosion resistance, and greater global availability, A383 / ADC12 is frequently chosen. When structural performance and excellent ductility are required, especially for heat-treatable parts, A356 or EN AC-43500 (AlSi10Mg) are strong options. For applications requiring maximum pressure tightness or leak prevention, A413 is the preferred choice. For premium surface finishing or decorative product lines, copper-based alloys such as Brass 380 or broader copper-brass alloys may be recommended. If ultra-thin walls or extremely high-fluidity casting is critical, silicon-rich alloys such as A413 or AC4C can be used.

Design Purpose
ADC14 was developed to provide a highly stable die-casting alloy that can produce intricate, thin-wall components with consistent quality across mass-production runs. The alloy’s optimized silicon content enhances fluidity, enabling precise filling of narrow channels, complex mold geometries, and deep ribs. The copper content reinforces mechanical strength and hardness, making ADC14 suitable for load-bearing designs. It targets applications where dimensional accuracy, durability, and reduced porosity are critical—such as transmission housings, heat-spreading enclosures, brackets, and high-precision mechanical structures. Paired with Neway’s engineering and prototyping support, ADC14 allows engineers to streamline multi-piece assemblies into a single robust die-cast component.
