Match casting aluminum alloys across ASTM/AA, JIS, EN AC and GB standards. Pick an alloy to see its equivalents, nominal composition and density — and settle the common "A380 vs ADC12" questions below.

No. A380 corresponds most closely to JIS ADC10 (higher copper ~3.5%, silicon ~8.5%). ADC12 equals A383 (more silicon ~11%, less copper ~2.5%), which fills thin walls better. They are often substituted but differ in chemistry, strength and fluidity — confirm the spec for your part.
Both are Al-Si-Cu die-casting alloys. A383 has higher silicon (better fluidity for thin, intricate parts) and lower copper (better resistance to hot cracking, slightly lower strength). A380 is the general-purpose default; choose A383 for complex thin-wall castings.
A356 (Al-Si7-Mg) is heat-treatable (T6), with higher ductility and leak-tightness — used for structural gravity and sand castings. A380 (Al-Si-Cu) is a high-volume die-casting alloy: higher as-cast strength and machinability, but not heat-treatable and lower corrosion resistance. Pick A356 for structural/pressure-tight, A380 for die casting.
A360 (Al-Si10-Mg) has added magnesium and little/no copper, giving better corrosion resistance and ductility. A380 contains ~3.5% copper for higher strength and machinability but lower corrosion resistance. Use A360 for corrosion/marine service, A380 for general strength and cost.
