High Purity Titanium Sponge | Technical Product Specification & Procurement Guide
High Purity Titanium Sponge is the primary metallic feedstock produced via the Kroll process and vacuum-distilled to remove residual magnesium and magnesium chloride. Engineered specifically for vacuum arc remelting (VAR) and electron beam (EB) melting, our titanium sponge provides ultra-low interstitial gas content and tightly controlled hardness. Backed by an annual production capacity of 5,000 metric tons, we deliver stable, large-scale supply solutions trusted by leading aerospace ingot makers and metallurgical foundries across North America and Europe.
Key Features
Ultra-Low Interstitial Elements: Minimized oxygen, nitrogen, and carbon levels prevent embrittlement during downstream melting.
Low Residual Chlorine & Magnesium: Advanced vacuum distillation reduces volatile impurities, minimizing porosity risks in cast ingots.
Uniform Particle Size Distribution: Cleanly crushed and sieved to optimize electrode compaction density and feeding rates.
Full Batch Traceability: Comprehensive documentation from reduction retorts to final drum packaging, meeting stringent aerospace quality standards.

FAQ
Q: Can you supply lower hardness grades for critical aerospace rotating parts?
A: Yes, we sort sponge fractions strictly by Brinell hardness (HBW) to meet specific tier-1 forging specifications.
Q: How do you prevent moisture absorption during ocean freight?
A: Drums are hermetically sealed under an inert argon atmosphere with internal desiccants to guarantee zero oxidation upon arrival.
Q: Are third-party inspections accepted?
A: Yes, inspection by SGS, BV, or equivalent certified agencies is welcomed prior to shipment.
