- Gr2 titanium foil
High-end global manufacturing has a high demand for qualified Gr2 titanium foil suppliers. Gr2 is a widely used grade of commercially pure titanium. It delivers balanced strength, excellent corrosion resistance and good workability. It sees extensive use in aerospace, chemical equipment, seawater desalination and new energy batteries. Major mass-production manufacturers of high-quality Gr2 titanium foil locate in China, the United States, Japan and Russia. This article analyzes core technical indicators and production capabilities for Gr2 titanium foil from a professional perspective.
1 Core Technical Indicators and Industry Standards for Gr2 Titanium Foil
1.1 Chemical Composition and Purity Control
Gr2 commercially pure titanium uses titanium as the base element. Its oxygen content stays below 0.25%. This index directly decides corrosion resistance and mechanical stability. Gr2 allows higher oxygen content than Gr1. Its tensile strength ranges from 345 MPa to 480 MPa, with elongation above 20%. Manufacturers keep iron content ≤ 0.30% and carbon content ≤ 0.08% to avoid material brittleness. Top producers adopt multiple vacuum arc remelting and real-time spectral monitoring. This ensures stable composition for long-term parts like seawater desalination heat exchangers and electrolytic electrodes.
1.2 Matching of Mechanical Properties and Microstructure
Gr2 titanium foil has yield strength between 275 MPa and 410 MPa. Annealed material features high ductility for deep drawing and bending. Cold worked material has higher strength for structural supports. Advanced manufacturers use continuous annealing furnaces with argon shielding and precise temperature control. The process forms uniform grains and reduces performance deviation between batches. It also guarantees high strength for welded joints.
1.3 Compliance with International Standards
Qualified Gr2 titanium foil needs to meet ASTM B265, JIS H4600 and EN 10095. Aerospace applications require UNS R50400 matching certificates. Chemical equipment and electronic products need valid material test reports. Reliable suppliers build full quality control systems covering raw material traceability to finished product testing. Every batch comes with complete inspection documents.
| Performance Index | Gr1 Titanium Foil | Gr2 Titanium Foil | Differences in Typical Applications |
|---|---|---|---|
| Tensile Strength (MPa) | 240 ~ 345 | 345 ~ 480 | Gr2 fits structural parts under medium load |
| Elongation (%) | ≥ 24 | ≥ 20 | Gr1 works better for superplastic forming |
| Oxygen Content (%) | ≤ 0.18 | ≤ 0.25 | Higher oxygen in Gr2 brings solid solution strengthening |
| Typical Working Conditions | Medical implants | Liners for chemical heat exchangers | Select grade based on service environment |

3 Key Criteria to Select Qualified Suppliers
3.1 Production Equipment Level
Traditional rolling mills struggle to control edge quality for ultra-thin foil. Multi-roll mills distribute force evenly and optimize edge conditions. Check production year, control system response and key component quality during equipment assessment. Modern production lines combine rolling mills and online thickness monitors for stable product quality.
3.2 Surface Cleaning Performance
Oil and dirt on titanium foil weaken corrosion resistance for chemical equipment. Top suppliers apply multi-stage cleaning and strict wettability tests. Special degreasing processes maintain high surface cleanliness for certified products.
3.3 Uniformity of Annealing Process
Continuous annealing furnaces run more efficiently than batch furnaces but require precise temperature regulation. Multi-zone heating and adjustable shielding gas avoid defects from improper heat treatment. Advanced lines equip real-time temperature monitors to keep uniform properties across full foil rolls.
3.4 Slitting and Edge Quality Control
Thin titanium foil easily develops burrs during slitting. High-precision slitters use premium blades and pressing systems for neat edges. Tight width tolerance acts as a key index for equipment performance. Visual inspection systems automatically detect surface and edge defects.
3.5 Full-process Quality Traceability
Aerospace and nuclear power industries require full traceability from ingot to finished foil. Each batch has exclusive codes linked to melting, rolling, annealing and testing records. Complete data tracking avoids quality risks for high-reliability projects.
3.6 Customization Capability
Many projects require non-standard sizes and surface finishes. Flexible manufacturers complete process verification and trial production quickly. Factories with modular production lines support small-batch custom orders.
3.7 Technical Service Support
Top suppliers provide working condition analysis, material selection and on-site inspection services. They run corrosion simulation and service life evaluation for complex environments.
