Tensile strength and corrosion resistance of GR2 is significantly better than that of GR1 titanium flat wire. It is made of high purity sponge titanium by hot and cold rolling precision processing and with uniform internal microstructure and grain size according to ASTM Grade 5 or above, which is beneficial to enhancing the performance of the material.

The tensile strength of the product reaches 550-700 MPa, which is about 15%-20% higher than that of GR1, and it retains the light weight strength of titanium alloy. In addition, it is highly resistant to stress corrosion in such severe media as sea water and chloride solution, and its service temperature can be extended up to between -253℃ and 300℃, satisfying more severe operation conditions.

Typical specifications of GR2 titanium flat wire from the technical parameter view: density about 4. Density is only 2.7 g/cm³ which is just 60% of that of steel and enables the construction to be lightweight; Elongation is >=18%, There is good plasticity in the course of forming; Elastic modulus is about 105 GPa, indicating that it has both rigidity and anti-fatigue property; after 1000h exposure in salt spray no corrosion stains could be seen, which means its corrosion resistance is much superior to that of GR1.

The product dimensions are designed for thicknesses of 0.1-3 mm and widths of 5-100 mm, with dimensional tolerances of ±0.05 mm. We offer various surface finishes including bright finish, pickling, sandblasting to comply with different processing demands. The product complies with international standards such as AMS 4902 and ASTM B265, and has a well-established material certification system.

In terms of application scenarios, GR2 titanium flat wire, with its superior performance advantages over GR1, is widely suitable for fields requiring higher strength and corrosion resistance. In the aerospace sector, it is used to manufacture engine peripheral structural components and fuel system pipeline supports, capable of withstanding high-pressure airflow erosion and fuel corrosion while reducing aircraft weight. In the medical device field, due to its excellent biocompatibility and resistance to bodily fluid corrosion, it is employed in high-end orthopedic implant connectors and surgical instrument spring components, meeting the safety requirements for long-term implantation in the human body. In marine engineering, GR2 titanium flat wire is used to produce anchor chain accessories and heat exchange elements for seawater desalination equipment, which can resist high salt spray and seawater erosion, extending service life by over 30% compared to GR1 materials. Additionally, in scenarios such as chemical pressure vessels and new energy vehicle battery connectors, GR2 titanium flat wire, with its higher strength reserve and high-temperature resistance, serves as an optimal alternative to GR1 materials, particularly suitable for high-end applications requiring both lightweight design and structural reliability.
