Titanium Sponge Dust

1. Product Overview
Titanium Sponge Dust is a high-purity, finely graded by-product of the Kroll process, consisting of particulate titanium sponge. It serves as a cost-effective feedstock for powder metallurgy, additive manufacturing, and pyrotechnic applications. Its strategic value lies in enabling manufacturers to achieve near-net-shape components with reduced machining waste, directly addressing global supply chain demands for lightweight, corrosion-resistant materials in aerospace, defense, and chemical processing.

2. Key Specifications & Technical Characteristics

• Chemical composition: ≥99.5% Ti (residuals: Fe ≤0.05%, Cl ≤0.10%, O ≤0.20%, N ≤0.03%, C ≤0.02%)

• Purity grade: Commercial pure (CP) – Grade 1–4 equivalent based on oxygen content customization

• Physical characteristics:

  • Fine granules / dust (irregular morphology)

  • Color: dark gray to metallic

  • Particle size: 0.1–1.5 mm (customizable, with <5% <0.045 mm fines)

  • Bulk density: 1.6–2.0 g/cm³

• Packaging options:

  • 25 kg airtight aluminum-lined bags

  • 200 kg steel drums with inert gas purge

  • 1 MT super sacks with inner moisture barrier

• Shelf life: 12 months in unopened, dry, inert atmosphere (≤0.5% moisture, no direct sunlight)

3. Core Industrial Applications

• Aerospace & defense: Powder metallurgy parts (actuators, fasteners, airframe brackets) – lower porosity and higher fatigue resistance than machined billet.

• Additive manufacturing (LPBF/EBM): Fine-grade dust serves as precursor for spherical powder atomization – reduces oxygen pickup by 30% vs. hydride-dehydride powder.

• Chemical processing: Production of porous titanium filters and spargers – superior corrosion resistance over stainless steel 316L in chloride environments.

• Pyrotechnics & energetic materials: High-purity Ti dust for military flares and delay compositions – consistent burn rate and low residue.

• Cost advantage: 35–50% cheaper than pre-alloyed powder for press-and-sinter operations, with same final density after sintering.

4. Competitive Advantages

• Quality consistency – Lot-to-lot analysis via ICP-OES and LECO gas analysis; each batch certified to ASTM B299/B348.

• Supply reliability – Multiple vertically integrated sources (China, Kazakhstan, Japan); 98% on-time delivery record for bulk contracts.

• Logistics capability – Hazmat-classified (UN 2878, Class 4.1) with DG-certified global shipping partners; door-to-door tracking.

• Price competitiveness – Direct mill contracts eliminate trader markups; pricing formula based on TiO₂ pigment feedstock index.

• Sustainability – Recyclable scrap capture program; 60% lower carbon footprint vs. virgin sponge due to optimized hydrocyclone classification.

• Technical support – Full SDS, CoA, powder compaction curves, and sintering profiles available; metallurgist consultation included for orders >10 MT.

5. Commercial & Supply Information

• Minimum order quantity (MOQ) – 1 MT (standard grades) / 5 MT (custom particle size distribution)

• Bulk loading capacity – 20 MT (net) per 20-foot container with drum packing

• Lead time – 15 days ex-warehouse (Houston / Rotterdam / Shanghai); 30 days for custom grades
