Aluminium Die Casting

ADC alloys, or aluminium-silicon die-casting alloys (including ADC12, ADC10 and ADC3), are widely adopted in automotive, electrical, electronics, home appliance and general engineering industries. They feature outstanding castability, good mechanical strength, corrosion resistance and fine surface quality, well suited for high-volume die casting.

Silicon content requires tight control because it directly affects melt fluidity, shrinkage and casting integrity. Other alloying elements including copper, magnesium, iron, manganese, zinc and nickel also need careful monitoring to balance strength, ductility and thermal properties. Excess iron forms brittle intermetallic phases, while unstable copper or magnesium content impairs corrosion resistance and heat treatment performance.

OES is commonly used for ADC alloy testing: raw material incoming inspection, melt composition monitoring, scrap sorting and final quality confirmation. Fast, repeatable and stable readings are essential in die-casting workshops, as real-time test results directly impact production efficiency and reject rates.
