ADC11 Die-Cast Aluminum Alloy: A general-purpose alloy with high silicon and medium copper content, characterized by a balance of good strength, excellent castability, and overall performance
As a typical representative of medium-silicon, medium-copper general-purpose die-casting aluminum alloys under the Japanese Industrial Standards (JIS), ADC11 is renowned for its good mechanical strength, excellent casting fluidity, moderate elongation, and outstanding overall balance of properties. This alloy utilizes silicon (Si) to ensure casting performance, while copper (Cu) serves as the primary strengthening element, enabling high strength and hardness in the as-cast condition while maintaining good die-casting processability. It represents a performance-balanced grade between ADC10 and ADC12. While maintaining high strength, it offers superior casting performance and toughness compared to ADC10. It is an ideal material for producing high-volume, complex-shaped die-cast parts with comprehensive requirements for strength and castability, and is widely used in the automotive, motorcycle, electronics and electrical, and general machinery industries.
