Titanium and Specialty Alloys: High-Performance Materials for Aerospace, Medical & Chemical Industries
2026/07/03
1. Commercially Pure Titanium Grades
| Grade | Tensile (MPa) | Yield (MPa) | Applications |
|---|---|---|---|
| Grade 1 | 240 | 170 | Chemical equipment, heat exchangers |
| Grade 2 | 345 | 275 | Most widely used: piping, vessels |
| Grade 3 | 450 | 380 | Pressure vessels, structural components |
| Grade 4 | 550 | 483 | Surgical implants, aerospace airframe |
2. Titanium Alloys
Ti-6Al-4V (Grade 5): Over 50% of all titanium usage. Tensile strength up to 950 MPa. Standard for aircraft engine compressor blades, discs, and medical implants.
Ti-6Al-4V ELI (Grade 23): Enhanced fracture toughness for critical aerospace components and premium medical implants.
Ti-3Al-2.5V (Grade 9): Improved cold formability. Aircraft hydraulic tubing and bicycle frames.
3. Nickel-Based Superalloys
Inconel 625 and 718 maintain strength above 1000°C — essential for jet engine hot sections and gas turbines. Hastelloy C-276 provides unmatched resistance to hydrochloric and sulfuric acid.
4. Procurement Considerations
Titanium commands 5-20x stainless steel pricing. Prioritize suppliers with AS9100 or ISO 13485 certifications. Full traceability with heat lot identification is non-negotiable. Lead times of 16-24 weeks for specialty grades make supply chain planning critical.
