What is aluminum alloy for casting?
2026-05-07
An aluminum casting alloy is a specially formulated aluminum-based material optimized for molten casting processes. Key characteristics include:
- High silicon content (typically 5–13%) to improve melt fluidity
- Low shrinkage and reduced porosity
- Good mold-filling ability
- Stable casting performance at 660–720°C
- Balanced strength, ductility, and machinability
Common standard casting alloys: ADC10, ADC12, A356, A357, A380, AlSi9Cu3, AlSi12. These are completely different from wrought alloys like 6061 and 7075.
