ADC12 Aluminum Alloy: Specifications, Properties, and Industrial Applications
ADC12 (also called A383) is one of the most commonly used materials in die casting. It is a Japanese name for a recycled die-cast aluminum alloy. Known for its excellent casting performance, cost-effectiveness, and mechanical properties, ADC12 is widely used in the automotive industry and daily life. From this article, you will learn about: The chemical composition of ADC12Mechanical properties of ADC12Why Choose ADC12 for Die CastingTop Applications of ADC12 Aluminum AlloyADC12 vs. Other Aluminum Die-Casting AlloysConclusion Chemical composition of ADC12 ADC12, a Japanese JIS standard alloy (equivalent to China’s YL113 and the U.S.’s A383), is a high-silicon aluminum alloy specifically designed for high-pressure die casting. Below are its primary specifications: Element Composition (%) Key Role Si (Silicon) 9.5 – 12.0 Enhances fluidity, reduces shrinkage, and improves castability. Cu (Copper) 1.5 – 3.5 Increases strength, hardness, and machinability. Fe (Iron) ≤1.3 Controls ductility; excess reduces toughness. Mg (Magnesium) ≤0.3 Balances hardness and mechanical properties. Zn (Zinc) ≤1.0 Improves corrosion resistance; excess may cause intergranular corrosion. Mn (Manganese) ≤0.5 Neutralizes iron’s harmful effects and stabilizes high-temperature performance. Al (Aluminum) Balance Base metal providing lightweight properties and structural integrity.
