AM Feedstock Titanium Bars & Wires for Powder Atomization

Ultra-Low Oxygen Titanium Feedstock for Additive Manufacturing & Powder Atomization

In spherical powder manufacturing for aerospace LPBF (Selective Laser Melting) and medical electron beam printing, the final powder quality is fundamentally constrained by the feedstock bar and wire chemistry. Powder atomization processes inevitably pick up trace ambient oxygen; starting with standard industrial-grade titanium bar (which typically carries 0.15%–0.20% oxygen) guarantees that recycled or even virgin powder will rapidly exceed ASTM F3001 and AMS 4999 oxygen thresholds.

Titanium Seller delivers certified low-interstitial, triple-VAR melted titanium feedstock bars and wires engineered specifically for the world’s leading atomization technologies: PREP, EIGA, PA, and WAAM.

1. PREP (Plasma Rotating Electrode Process) Feedstock Bars

• Dimensions: $\Phi 30\text{ mm} \sim \Phi 100\text{ mm}$, cut lengths up to $1500\text{ mm}$.
• Machining & Balance: Turned and precision ground with strict dynamic balancing; total radial runout $\le 0.05\text{ mm}$ to ensure smooth rotation at speeds up to 15,000–30,000 RPM without plasma torch wobble.
• End Connections: Available with custom precision internal threads, drive flats, or Morse tapers per your atomizer mounting chucks.

2. EIGA (Electrode Induction Melting Gas Atomization) Feedstock Bars

• Dimensions: $\Phi 20\text{ mm} \sim \Phi 50\text{ mm}$, lengths up to $1200\text{ mm}$.
• Crucible-Free Purity: Produced with zero refractory or ceramic contact. When inductively melted at the cone tip, the ultra-low oxygen chemistry prevents surface oxide crusting, resulting in spherical powders with $>95%$ high sphericity and minimal satellite formation.

3. WAAM (Wire Arc Additive Manufacturing) & PA Feedstock Wires

• Dimensions: $\Phi 0.8\text{ mm}, \Phi 1.2\text{ mm}, \Phi 1.6\text{ mm}, \Phi 2.0\text{ mm}, \Phi 3.2\text{ mm}$.
• Superior Straightness: Uncoiled free-wire straightness strictly within $< 8\text{ mm/m}$. Feeds continuously through automated push-pull welding torches without curling, jamming, or arc wandering.
• Surface Condition: Dry-drawn with proprietary micro-lubricants followed by inline solvent degreasing. Zero hydrocarbon residue ensures pore-free deposition in multi-layer WAAM structural prints.

Complete Quality Assurance & Dispatch

1. Full-Length Ultrasonic Inspection: Every PREP/EIGA bar undergoes 100% rotary immersion ultrasonic testing (UT per AMS 2631 Class AA / ASTM E2375) to guarantee zero high-density (HDI) or low-density (LDI) inclusions.
2. Double-Ended Chemical Sampling: Chemical composition, including ONH gas analysis, is verified at both the ingot top and bottom, as well as on finished bar samples.
3. Packaging: High-cleanliness vacuum-sealed plastic sleeves, desiccant bags, and heavy-duty ISPM-15 wooden cases prevent transit corrosion and oxidation.
