Notes:
GR2 is the most commonly used commercially pure titanium grade, widely applied in chemical, marine, and aerospace industries.
Diameter selection depends on material thickness, welding method (TIG or MIG), and application requirements.
Surface finish options: bright (high polish), annealed (soft), half-hard (medium strength).



The grade characteristics of GR2 titanium wire are extremely distinctive. Compared with other pure titanium grades, it has excellent corrosion resistance and processing formability. It can maintain stable chemical properties in complex environments such as neutral salt spray, organic acids, seawater, etc. It is non-magnetic and has excellent biocompatibility. At the same time, it has moderate strength and good weldability, and can achieve high-quality processing without complex processes. Different application scenarios have precise requirements for its size parameters. In the chemical industry, it is mainly used for weaving and welding corrosive medium transport pipelines, with a suitable size range of 1.0mm-3.2mm, and can withstand long-term corrosion from acidic and alkaline solutions; In marine engineering, it is commonly used for guardrails on offshore platforms and connectors for underwater instruments, with commonly used sizes ranging from 1.6mm to 4.0mm, which can resist strong corrosion and tidal impact of seawater; In the field of medical devices, it is used for the manufacturing of surgical instruments and rehabilitation equipment, with sizes ranging from 0.5mm to 1.2mm, relying on excellent biocompatibility to avoid human rejection reactions; The precision electronics field is compatible with electronic component pins and sensor wires, with sizes ranging from 0.3mm to 1.0mm, which can meet the dimensional accuracy requirements of precision machining.
GR2 titanium wire has many core advantages and is an ideal titanium material choice for medium to low strength working conditions. Its density is only 4.51g/cm ³, much lower than stainless steel. After use, it can significantly reduce the weight of the product, especially suitable for lightweight products that require weight reduction; Outstanding corrosion resistance, no additional coating protection is required in most corrosive environments, which can significantly reduce maintenance costs in the later stage; Excellent ductility, capable of various processing such as drawing, bending, weaving, etc., with good forming effect and less prone to problems such as fracture and deformation; In addition, its thermal and electrical conductivity is stable, and it can maintain good mechanical properties in both high and low temperature environments, with a wide range of applicable temperatures. On the basis of retaining these advantages, our GR2 titanium wire has further improved the consistency of product performance and processing stability by optimizing the melting process and strictly controlling impurities such as oxygen and iron.
