Titanium Powders
Titanium powders for DMLS and EBM are produced by gas atomization in inert atmosphere to minimize oxygen pickup (O < 0.13% for ELI grade). Particle size distributions are laser diffraction-certified per lot: D10, D50, D90 measurements with certificate of analysis. Available grades:
- Ti6Al4V Grade 23 (ELI) — 15–45µm DMLS, 45–105µm EBM; ASTM F3001
- Ti6Al4V Grade 5 (standard) — 15–45µm DMLS; AMS 4999
- CP Titanium Grade 2 — 15–45µm for corrosion applications
- Ti-5553 (beta alloy) — on request for aerospace research
Each lot includes CoA: chemistry (ICP-OES), particle size (laser diffraction), flowability (Hall flowmeter), apparent density (Scott volumeter).
Steel & Stainless Powders
Stainless and tool steel powders for DMLS cover the widest range of structural applications in additive manufacturing:
- 316L stainless — 15–45µm; austenitic, corrosion-resistant; ASTM A276
- 17-4 PH stainless — precipitation-hardenable; 1,310–1,380 MPa after H900 aging
- M2 high-speed steel — for cutting tools, wear surfaces; 64 HRC after heat treatment
- H13 hot-work tool steel — for injection mold tooling inserts with conformal cooling
- MS1 maraging steel (18Ni300) — 1,900 MPa after aging; highest strength DMLS material
All stainless powders: oxygen content < 300 ppm, nitrogen < 100 ppm.
Aluminum & Nickel Powders
Aluminum and nickel superalloy powders address two extremes of DMLS application: lightweight structural parts and high-temperature components.
Aluminum:
- AlSi10Mg — the workhorse DMLS aluminum; 345 MPa UTS, 2.67 g/cm³; AMS 4227
- AlSi12 — higher Si for improved flowability and build rate
- Scalmalloy (Al-Mg-Sc) — premium; 520 MPa UTS, best fatigue resistance
Nickel superalloys:
- Inconel 718 — 958 MPa UTS, stable to 700°C; AMS 5662; most-specified DMLS nickel alloy
- Inconel 625 — superior corrosion resistance; marine and chemical processing
- Hastelloy X — for gas turbine combustion components up to 1,080°C
CoCr & Specialty Alloys
Specialty alloy powders serve niche but high-value applications in DMLS:
CoCr alloys:
- CoCrMo (ASTM F75) — the primary alloy for orthopedic and dental implants; ISO 5832-4
- CoCrW — for dental prosthetics; Vickers hardness 350–420 HV
Copper alloys:
- CuCr1Zr — 330 W/m·K thermal conductivity; for induction coils, heat exchangers, rocket combustion chamber liners
- Pure copper (Cu) — selective laser melting only; for electrical applications
Precious metals:
- Gold 18k, platinum, and palladium powders available on request for jewelry and dental applications
