3. Technical Specifications

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.
