🧭 4. Detailed Application Areas
-
Used in aluminum alloy production to introduce titanium for grain refinement.
-
Common in AlSi, AlMg, AlCu systems requiring controlled microstructure.
-
Applied in automotive, aerospace, and structural casting for enhanced mechanical properties.
-
Suitable for continuous casting, billet production, extrusion feedstock.
-
Titanium acts as a nucleating agent, promoting fine grain formation during solidification.
-
Typically added to molten aluminum in controlled amounts, depending on alloy target.
🚨 5. Mandatory Use Cases
-
Required in high-performance aluminum alloys where grain refinement is critical.
-
Aerospace-grade castings and automotive engine components often mandate Ti addition.
-
Compliance with standards such as AMS 4289, ASTM B928, EN 573 may require AlTi master alloy usage.

🏭 9. Production Details
-
Manufacturing Process: Titanium is alloyed into molten aluminum under controlled conditions, forming intermetallic compounds (e.g., Al₃Ti) that act as nucleants.
-
Producing Countries: China, Germany, India, Türkiye
-
True Producers vs. Traders: Direct producers offer consistent Ti content and phase stability. Traders may vary in quality and origin.
Origin verification and phase analysis (Al₃Ti vs. TiB₂) are critical for performance assurance.
