⚙️ 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.
