Overview

Aluminum-Boron (Al-B) Master Alloy is primarily used as a grain refiner in the aluminum industry. Adding small amounts of boron (B)—typically via master alloys like Al-5B or Al-3B—can significantly improve the grain structure of aluminum and its alloys during solidification, leading to enhanced mechanical properties and improved casting quality.

Key Benefits

  1. Grain Refinement

    • Produces fine, equiaxed grain structures, reducing casting defects like hot cracking and porosity.

  2. Improves Mechanical Properties

    • Increases tensile strength, ductility, and fatigue resistance in wrought and cast aluminum alloys.

  3. Enhances Surface Finish & Machinability

    • Fine grains improve homogeneity and reduce segregation.

Applications

  • Aluminum Foundries

    • Used during melt treatment to ensure fine grain castings.

  • Aerospace & Automotive Alloys

    • Applied in high-performance Al-Si, Al-Mg, Al-Cu, and Al-Zn systems for structural components.

  • Wrought Aluminum Products

    • Improves formability and consistency in rolled or extruded products.

  • Additive Manufacturing (AM)

    • Can be used in powder metallurgy to control grain structure in printed aluminum parts.
