Product Description
AlNb60 Niobium Aluminum Master Alloy — Granules 3–6 mm
HIGH BROAD AlNb60 is a vacuum-grade niobium-aluminum master alloy with a nominal 60% Nb content (Nb 55–65 wt%, Al balance), supplied as granules in 3–6 mm. It is engineered for marine corrosion-resistant alloy melting, delivering a stable niobium recovery rate, excellent dissolution and wetting, and low segregation for consistent, repeatable melts.

Product Features
- Stable niobium recovery rate with excellent dissolution and wetting behavior; pure Nb is refractory, while AlNb60 greatly lowers the addition difficulty.
- β-phase stabilizing element that refines grain structure and improves high-temperature strength, creep resistance, corrosion resistance and thermal stability.
- Low segregation, uniform composition and strong batch-to-batch consistency, suitable for continuous and vacuum melting.
- High purity and uniform composition — ideal for high-end and demanding melt shops.
Core Applications
- Marine corrosion-resistant alloys
- Seawater-exposed structural components
- Offshore engineering materials
Packaging & Delivery
- Packaging: Moisture-proof anti-rust aluminum foil vacuum bag / iron drum with inner moisture-proof bag, 25 kg per drum or 1000 kg ton bag.
- Trade terms: FCA, FOB, DAP; exportable to the EU and Russia.
- MOQ: 25 kg, with larger tonnage scheduling and expedited trial orders available.
Quality Assurance
Each batch can be supplied with a Certificate of Analysis (COA), spectral test report and MSDS. Production is carried out to internal AMS / EN1676 control standards, and a high-purity controlled-impurity version is available on request.
