Which Aluminum Alloys Are Best for Smartphone or Smartwatch Enclosures?
AlSi10Mg – Lightweight, Durable, and Anodizing-Compatible
AlSi10Mg is one of the most preferred aluminum alloys for high-end consumer electronics like smartphones and smartwatches. It offers a high strength-to-weight ratio, excellent corrosion resistance, and superior surface finish after anodizing. Its good thermal conductivity and minimal shrinkage during casting allow for thin-walled structures down to 1.0 mm, ideal for compact enclosures that demand tight dimensional tolerances and premium aesthetics.
A360 – Superior Fluidity and Pressure Tightness
A360 provides enhanced fluidity and pressure tightness, making it ideal for intricate enclosures with detailed features and internal channels. It also offers improved corrosion resistance over A380, which is critical in wearable electronics constantly exposed to sweat, skin oils, and environmental moisture. A360 is frequently selected for waterproof smartwatch housings and mobile device frames requiring internal sealing.
ADC12 – Cost-Effective and Dimensionally Stable
ADC12 is a cost-effective alternative with excellent castability and dimensional stability. Its ability to maintain tight tolerances and its compatibility with decorative surface treatments—such as powder coating and painting—make it a popular choice for mid-range smartphone cases and accessory frames.
AlZn10Si8Mg – High Strength with Premium Appearance
AlZn10Si8Mg offers enhanced mechanical strength and excellent surface finish, ideal for smartwatch bodies that need to withstand mechanical shock and daily wear. This alloy also supports fine detailing and uniform anodizing for a sleek, premium appearance while offering long-term durability.
