Aluminum Titanium Boron Master Alloy

Aluminum Titanium Boron Master Alloy is a multi-element master alloy with aluminum (Al) as the matrix and titanium (Ti) and boron (B) as composite alloying elements. Available in Ti5B1, Ti5B0.2, and Ti3B1 grades corresponding to different Ti-B ratios to meet the grain refinement needs of different aluminum alloy systems. The product is supplied in four forms: stick, coil, waffle ingot, and cast cut bar (CCB). Sticks and coils suit online automatic addition on continuous casting lines; waffle ingots suit manual batch addition in batch smelting; CCB accommodates both automated feeding and flexible cutting. The recommended feed rate is 0.4%–0.6%; its core function is grain refinement.

[Key Advantages]
· Three grades—Ti5B1, Ti5B0.2, and Ti3B1—cover different Ti-B ratio refinement requirements for precise selection based on target alloy system and refinement effect.
· The combined action of titanium and boron generates abundant dispersed TiB₂ and AlB₂ nucleation particles in aluminum melts, significantly refining as-cast grains and improving ductility, strength, and formability.
· Stick and coil forms support continuous casting online automatic addition with precise and stable dosing, ensuring consistent refinement in continuous production; waffle ingot and CCB forms offer flexible batching for batch smelting and multi-variety small-batch production.
· Recommended feed rate of 0.4%–0.6% allows precise control based on alloy grade and casting process, with significant and stable refinement effects.
· Uniform composition and reliable quality; all forms meet the full-process requirements from laboratory R&D to industrial mass production.

[Product Uses]
· Core application: grain refinement; recommended feed rate 0.4%–0.6% — widely used in smelting batching of cast and wrought aluminum alloys to effectively refine as-cast grains and improve overall mechanical properties and workability.
· In aluminum alloy continuous casting and continuous casting-rolling production, stick or coil forms are added online via automatic feeders for precise and stable refiner input; widely applied in aluminum plate/strip, foil, and cable production.
· Suitable for batch smelting of cast aluminum alloys (e.g., A356, 6xxx, 7xxx series) using waffle ingot or CCB form to refine casting grains and improve mechanical properties, elongation, and fatigue resistance.
· In aerospace high-strength alloys, automotive lightweight alloys, and high-end electronic aluminum alloys, precise control of the 0.4%–0.6% addition achieves accurate microstructure control, ensuring stable and consistent product performance.
