Is aluminum alloy forged or cast?
2026-05-07
Aluminum alloys can be both cast and forged, depending on the alloy grade and manufacturing process.
- Cast aluminum alloys: Designed for casting processes; high silicon content for fluidity; examples: ADC12, A356, A380. Advantages: complex shapes, low tooling cost, mass production.
- Wrought aluminum alloys: Used for forging, extrusion, rolling; examples: 6061, 7075, 5052, 6063. Forged aluminum has higher density, better fatigue resistance, and tighter tolerances.
In short: Casting = shape complexity & cost efficiency; Forging = higher strength & structural integrity.
