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
-
Grain Refinement
-
Produces fine, equiaxed grain structures, reducing casting defects like hot cracking and porosity.
-
-
Improves Mechanical Properties
-
Increases tensile strength, ductility, and fatigue resistance in wrought and cast aluminum alloys.
-
-
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.
