Copper Free Steel MIG Wire SIFMIG ZERO SG3 – 1.0 mm (250 Kg POP)

Sifmig Zero SG3 is a high-quality MIG wire that is free from copper coating, ensuring a cleaner deposit and avoiding metallurgical risks associated with increased copper in the weld pool. Manufactured with an uncoppered finish, it offers better feeding, conductivity, and a higher ultimate tensile strength compared to standard SIFMIG SG2.

Features and Benefits:

  • Copper-Free: Ensures a cleaner deposit and minimizes metallurgical risks.
  • Enhanced Composition: Contains increased manganese and silicon to offer improved mechanical properties.
  • High-Quality Finish: Provides better feeding and conductivity.
  • Ideal for Automation: Offers arc-stability characteristics and improved feedability, making it perfect for robotic or automated processes.
  • Less Cleanup: The absence of copper results in less post-weld cleanup, reducing the need for grinding.

Common Applications:

  • General fabrication
  • Construction
  • Shipbuilding
  • Tanks and boilers
  • Autobody applications
  • Robotic and automated processes
  • Welding of mild steels, structural steel, fine-grain steel, pipe steel, boiler steel, and cast steel.
