The Zirconium ERZr2 Welding Wire is made from commercially pure zirconium (typically over 99.2% Zr) with very few impurities, including iron, oxygen, nitrogen, and hafnium. This specific composition guarantees remarkable corrosion resistance, particularly in acidic environments, along with excellent weldability. The wire boasts impressive mechanical properties, featuring a tensile strength of around 380–470 MPa, high ductility, and robust resistance to cracking and embrittlement. ERZr2 welding wire delivers clean, defect-free welds and superior metallurgical compatibility with zirconium base materials, making it perfect for precision welding in critical applications.
