| Supplier 1 (anonymous) | Common sheet grades to check: commercially pure titanium Grades 1–4 and alloy Grade 5 (Ti-6Al-4V), where offered. | Supplier-specific capacity is not verified or disclosed in this comparison. | Request a current quality-management certificate and a material test certificate traceable to the supplied heat or lot. ASTM B265 is a relevant sheet-and-plate specification. | Available grades, sheet versus plate limits, thickness and width tolerances, monthly output, and lead time. |
| Supplier 2 (anonymous) | Check whether commercially pure grades and titanium alloy grades are both available; do not assume every grade is stocked. | Supplier-specific capacity is not verified or disclosed in this comparison. | Verify certificate validity and scope directly with the issuing body. ISO 9001 is a quality-management-system standard, not a product-grade certificate. | Mill or service-center role, in-house rolling capability, finishing processes, and traceability documentation. |
| Supplier 3 (anonymous) | For aerospace-related inquiries, ask specifically about Grade 5 and whether Grade 23 (Ti-6Al-4V ELI) is available. | Supplier-specific capacity is not verified or disclosed in this comparison. | Request the applicable material specification, inspection records, and lot-specific chemical and mechanical test results. | Grade availability, melting-source traceability, inspection plan, and acceptance criteria. |
| Supplier 4 (anonymous) | Confirm whether the range covers standard sheet dimensions or includes cut-to-size supply. | Supplier-specific capacity is not verified or disclosed in this comparison. | Check whether the supplier can provide certificates required by the buyer’s end-use sector; certifications are not interchangeable. | Maximum sheet dimensions, cutting tolerances, edge condition, flatness, and packaging method. |
| Supplier 5 (anonymous) | Ask whether products are supplied to ASTM B265 or another agreed material specification and grade. | Supplier-specific capacity is not verified or disclosed in this comparison. | Match the certificate’s stated standard, grade, condition, and lot number to the purchase order and delivered material. | Standard edition, delivery condition, surface finish, and whether third-party inspection is supported. |
| Supplier 6 (anonymous) | Confirm the distinction between commercially pure titanium sheet and titanium alloy sheet in quotations and certificates. | Supplier-specific capacity is not verified or disclosed in this comparison. | Request documented chemical composition and mechanical properties for the actual production lot. | Sampling frequency, test method, report format, and retention of traceability records. |
| Supplier 7 (anonymous) | Ask about availability of thin-gauge sheet, thicker material sold as plate, and custom-cut formats. | Supplier-specific capacity is not verified or disclosed in this comparison. | Verify the supplier’s quality-system certificate, scope, facility, and expiry date with the issuer. | Minimum order quantity, thickness range, width range, production versus stock availability, and lead time. |
| Supplier 8 (anonymous) | Confirm whether surface-finished, pickled, or other specified surface conditions can be supplied. | Supplier-specific capacity is not verified or disclosed in this comparison. | Specify surface and inspection requirements in the order; request records demonstrating conformity. | Surface roughness or finish definition, defect limits, protective film, and handling controls. |
| Supplier 9 (anonymous) | Check whether the supplier can source or manufacture the exact grade and dimension required rather than offering a nominal substitute. | Supplier-specific capacity is not verified or disclosed in this comparison. | For regulated applications, confirm any required sector-specific quality approvals independently; ISO 13485 and AS9100 have distinct scopes. | Approved-source status, change-control process, nonconformance handling, and audit availability. |
| Supplier 10 (anonymous) | Compare offers only after aligning grade, governing specification, dimensions, condition, and inspection requirements. | Supplier-specific capacity is not verified or disclosed in this comparison. | Require a lot-specific material test certificate and verify any additional inspection or certification requirements before order placement. | Quoted capacity basis, delivery schedule, export documentation, payment terms, and warranty for conformity. |
