ADC10

Versatile ADC10 aluminum alloy combining excellent castability, strength, and surface finish for high-volume die castings.

Material Introduction

ADC10 is a widely used aluminum alloy engineered specifically for high-volume ADC10 aluminum die casting applications. As a typical Al–Si–Cu casting alloy, it offers an excellent balance of castability, mechanical strength, and dimensional stability, making it one of the most popular choices for thin-wall and complex housings. Its silicon-rich composition ensures smooth mold filling and low defect rates, while controlled copper levels provide robust strength and fatigue resistance without excessive brittleness. Paired with Neway’s advanced aluminum die casting cells and precision tool and die making, ADC10 delivers consistent performance in demanding applications such as electronic enclosures, automotive modules, and precision mechanical components.

Alternative Material Options

When project requirements exceed ADC10’s capabilities or demand a different performance balance, several alternative alloys are available. For slightly higher strength, pressure tightness, and broader global standardization, A380 is a close relative and one of the most specified aluminum die-casting alloys worldwide. If improved fluidity and corrosion resistance are prioritised for intricate or exposed components, A383 / ADC12 is often selected. Where superior pressure tightness or leak-free performance is critical, such as pump and hydraulic housings, A413 or similar alloys can be advantageous. For excellent ductility and heat-treatable performance in structural parts, alloys like A356 or EN AC-43500 (AlSi10Mg) are strong candidates. When fine detail, corrosion resistance, or luxury appearance take priority over weight, copper-based materials such as Brass 380 or broader copper-brass alloys may be recommended.

Design Purpose

ADC10 was developed to provide a robust, general-purpose aluminum die-casting alloy capable of producing lightweight, dimensionally stable, and cost-effective parts for high-volume programs. Its silicon content delivers excellent fluidity and a low hot-tearing tendency, enabling the production of thin-wall castings with intricate ribs, bosses, and fine details. Controlled levels of copper and other alloying elements enhance tensile and yield strength, allowing for the support of structural housings, brackets, and frames with reduced section thickness. The alloy is intended to work well in modern high-pressure metal casting cells, maintaining good pressure tightness and minimal porosity when process parameters and die design are optimized. In combination with Neway’s design and engineering support, ADC10 allows engineers to reduce part count, consolidate functions, and shorten product development cycles for electronics, automotive, and industrial equipment.

Key Material Characteristics

  • Excellent castability and fluidity for high-pressure aluminum die casting of thin-wall, complex components.

  • Balanced strength-to-weight ratio suitable for structural housings, brackets, and heat-dissipating covers.

  • Good dimensional stability and low shrinkage, supporting tight tolerance control in high-volume production.

  • Moderate pressure tightness with proper process control, ideal for enclosures and semi-sealed components.

  • Good machinability for secondary post machining of precision functional features.

  • Compatible with a wide range of post processes, including deburring, surface texturing, and protective coatings.

  • Efficient heat transfer due to aluminum’s high thermal conductivity, useful for electronics and motor housings.

  • High corrosion resistance, further enhanced by powder coating, painting, or anodic finishes.

  • Anti-soldering behavior and stable die lubrication windows, helping extend tooling life and reduce downtime.

  • Well-suited to part consolidation strategies that replace multi-piece steel or plastic assemblies with a single casting.

Manufacturability And Post Process

  • High-pressure aluminum die casting: Primary process for ADC10, ideal for thin-wall, high-precision housings and frames.

  • Sand casting: Suitable for larger prototypes or low-volume structural components using similar Al–Si–Cu chemistry.

  • Rapid tooling / rapid prototyping: Allows early validation of ADC10 design concepts before investing in full production tooling.

  • Insert casting: Integrates steel shafts, threaded inserts, or copper elements into a single ADC10 casting to simplify assembling.

  • Post machining: Boring, milling, and tapping to achieve ±0.02–0.05 mm tolerances on critical faces and bores.

  • Drilling and thread formation: Suitable for tapped holes, self-tapping screw bosses, and precision mounting interfaces.

  • Tumbling and vibratory finishing: Efficient deburring and edge smoothing for cosmetic and safety-critical parts.

  • Integrated assemblies: Neway combines ADC10 castings with machined, stamped, or plastic parts in dedicated assembly cells.
