Typical Density: 2.66-2.70 g/cm3
Key Applications: Automotive lightweighting (EV body structures, chassis), aerospace non-structural, heat exchangers, prototyping, consumer products
Production: VIGA standard; inert gas atomization with moisture control critical (aluminum powder is hygroscopic and reactive)
Market Position: Fastest-growing segment driven by automotive EV lightweighting. AlSi10Mg dominates SLM aluminum. Scalmalloy (AlMgSc) is a premium aerospace-grade variant.

### Nickel Superalloy Powders (High-Temperature Specialists)

## Production Methods & Technology
### VIGA — Vacuum Induction Melting Inert Gas Atomization
Process: Raw material melted in a ceramic crucible under vacuum → molten metal stream broken by high-pressure
  inert gas (argon/nitrogen) → rapid solidification into spherical powder particles.
Characteristics: Most common method (80%+ of AM powders). Spherical morphology, good flowability.
  Typical size: 15-53 um for LPBF, 53-150 um for DED. Cost-effective for steels and nickel alloys.
Limitations: Potential ceramic inclusion from crucible. Not ideal for ultra-high-purity reactive metals.

### EIGA — Electrode Induction Melting Inert Gas Atomization
Process: Rotating electrode bar melted by induction coil → molten metal falls directly into gas atomization
  zone → no contact with crucible or ceramic components.
Characteristics: Crucible-free = ultra-clean powder. Preferred for reactive metals (titanium, zirconium).
  Lower oxygen pickup. 15-40% cost premium over VIGA. Typical for biomedical and aerospace titanium.
Limitations: Lower throughput than VIGA. Electrode preparation adds cost.

### PREP — Plasma Rotating Electrode Process
Process: Rotating alloy bar melted by plasma arc → centrifugal force throws droplets outward →
  spherical solidification in inert atmosphere.
Characteristics: Most spherical powder achievable, narrowest size distribution, excellent flowability.
  Premium quality for critical aerospace applications. 30-60% price premium over VIGA.

### GA — Gas Atomization (Atmosphere Melting)
Process: Metal melted in air or inert atmosphere → gas atomization → powder collection.
Characteristics: Wide size range, cost-effective for non-critical applications. May have higher oxygen.

### WA — Water Atomization
Process: Molten metal stream disintegrated by high-pressure water jets → irregular particle shapes.
Characteristics: Lower cost, irregular morphology, higher oxygen. Used for press-and-sinter PM, not AM.
