HZH-10.8 Series Anodizable Die-Casting Aluminum Alloy

Conventional anodizing aluminum alloys are mainly based on wrought aluminum alloy systems, which offer high strength and excellent anodizing performance. However, their manufacturing processes are relatively long, with high post-processing costs such as CNC machining. They also have disadvantages including high material waste and poor environmental sustainability.

Conventional die-casting aluminum alloys are typically Al-Si alloy systems with good fluidity and high strength. However, their high silicon content (>6%) results in the formation of coarse primary silicon phases during solidification, causing powdering and discoloration issues during anodizing. Therefore, they are generally only suitable for matte black anodized appearances with low color requirements and cannot meet the demands of multi-color anodized finishes.

The HZH-10.8 Series Anodizable Die-Cast Aluminum Alloy features high mechanical strength, excellent surface quality, and superior fluidity. It can meet the requirements of complex structural components with multi-color anodized appearances, providing a high-quality solution for advanced 3C products and precision aluminum applications.
