Types, Composition, and Properties of Spherical Titanium Alloy Powder
Not all titanium alloys are created equal. Depending on the intended application, different formulations of Spherical Titanium Alloy Powder offer unique properties. The most common titanium alloy used in powder form is Ti-6Al-4V (Grade 5), but there are other variations tailored for specific uses.
| Alloy Type | Composition (Wt%) | คุณสมบัติสำคัญ | แอปพลิเคชันทั่วไป |
|---|---|---|---|
| Ti-6Al-4V (Grade 5) | Ti: 90%, Al: 6%, V: 4% | High strength, excellent corrosion resistance, biocompatibility | Aerospace, medical implants, 3D printing |
| Ti-6Al-4V ELI (Grade 23) | Ti: 90%, Al: 6%, V: 4% (Extra Low Interstitials) | Enhanced toughness, better fatigue resistance | Biomedical implants, surgical tools |
| Ti-5Al-2.5Sn | Ti: 92.5%, Al: 5%, Sn: 2.5% | High creep resistance, good weldability | Aerospace components, high-temperature parts |
| Ti-15V-3Cr-3Al-3Sn | Ti: 85%, V: 15%, Cr: 3%, Al: 3%, Sn: 3% | Excellent ductility, good cold formability | Aerospace structures, chemical processing |
| Ti-10V-2Fe-3Al | Ti: 85%, V: 10%, Fe: 2%, Al: 3% | High strength, good fatigue resistance | Automotive, aerospace |
Why Composition Matters:
The composition of the alloy directly influences its mechanical properties and performance in different environments. For example, คุณ-ชัล-เฮวี is the most widely used titanium alloy due to its balanced combination of strength, corrosion resistance, and biocompatibility. Ti-15V-3Cr-3Al-3Sn, on the other hand, is ideal for applications where ductility and cold formability are more critical.
Spherical Titanium Alloy Powder Properties and Characteristics
