Aluminum Casting Alloy Selector
Choose the right aluminum casting alloy for your application — from A356 to ADC12, A380 and A413.
How it decides
The recommendation matches your application to the alloy whose castability, strength and corrosion balance fit best.
Common casting alloys
| Alloy | Best for |
|---|---|
| A356-T6 | All-round sand/gravity, good strength + ductility |
| A380 / ADC12 | High-volume die casting |
| A413 | Thin-wall, intricate die castings |
| 535 | Marine / corrosion resistance |
Frequently Asked Questions
Which aluminum casting alloy should I use?
For general sand/gravity casting, A356-T6; for high-volume die casting, ADC12 or A380; for thin walls, A413; for corrosion, 535.
What is the difference between A356 and A380?
A356 is an Al-Si-Mg alloy (heat-treatable, ductile, used in sand/gravity casting); A380 is an Al-Si-Cu die-casting alloy (great fluidity, lower ductility).
Which alloy is best for thin walls?
A413, thanks to its high silicon content and excellent fluidity.
Which is most corrosion resistant?
535 (Al-Mg), favored for marine and corrosive environments.
