Product Description

Aluminum Niobium AlNb Master Alloy

The Aluminum Niobium (AlNb) Master Alloy is a high-purity intermediate alloy containing 5-20% Niobium (Nb), specifically designed for refining grain structure and improving weldability in high-strength aluminum alloys. This master alloy ensures precise and homogeneous element distribution in the aluminum melt, reducing segregation and improving overall alloy quality.

Key Benefits

  • Delivers exceptional grain refinement, improving strength, toughness, and weld performance
  • Precise composition control with minimal element loss during melting
  • Homogeneous microstructure ensures consistent performance batch after batch
  • Low melting point range (700-800°C) enables rapid dissolution in aluminum melts
  • Available in Waffle Ingot form for easy handling, weighing, and addition to molten aluminum

Applications

  • Grain refinement and microstructure modification in aluminum casting
  • Composition adjustment for aluminum alloy production
  • Improving specific mechanical, thermal, or physical properties of aluminum products
  • Suitable for sand casting, die casting, permanent mold casting, and continuous casting processes
