Features
  • ERTi-7 performs exceptionally well in highly corrosive environments, including strong acids, alkalines, and high salt concentrations, offering effective protection against corrosion. This helps extend the lifetime of equipment and reduces maintenance costs.
  • This alloy demonstrates outstanding stability at elevated temperatures, withstanding high temperatures up to several hundred degrees Celsius or even higher, without significant degradation in performance.
  • ERTi-7 provides excellent machinability and weldability, allowing for precise processing and construction of complex structures, thereby enhancing material efficiency.
Applications

ERTi-7 is widely used in welding mechanical equipment, especially in environments that demand high corrosion resistance and high-temperature performance. It is particularly suitable for industries such as:

  • Chemical industry: Ideal for welding components exposed to corrosive substances
  • Petroleum industry: Used in the production of equipment for handling aggressive environments

Recommended Welding Method
  • Tungsten inert gas welding (TIG welding)
    TIG welding is a widely used method for titanium alloy welding. In this process, tungsten serves as the electrode, and argon is used as the shielding gas. The electric arc melts the joint between the titanium alloy plates to form the weld. TIG welding offers high-quality welds and aesthetic, smooth seams.
  • Metal inert gas welding (MIG welding)
    Compared to TIG welding, MIG welding uses a consumable electrode (welding wire) and argon as the shielding gas. This method is ideal for welding thicker titanium alloy plates and provides higher welding efficiency.
  • Laser welding
    Laser welding uses a high-energy beam to create deep, narrow welds, making it suitable for welding thin-walled materials. This method provides high-quality welds, high welding efficiency, and minimizes weld distortion.
