Zirconium 705 alloy (UNS R60705) is characterized by outstanding corrosion resistance and improved mechanical properties, achieved through niobium alloying. EV Group China supplies a wide range of semi-finished products made from this alloy, strictly complying with international ASTM standards, ensuring the highest quality and reliability for critical applications:

  • ASTM B493 — forgings from zirconium alloys, guaranteeing strength and durability.
  • ASTM B523 — seamless and welded tubes for heat exchange equipment, ensuring optimal heat transfer and resistance to aggressive media.
  • ASTM B550 — bar stock and wire, used in high-tech structures and components.
  • ASTM B551 — flat rolled products (sheets, plates, strips), intended for the manufacture of large-sized products and cladding.
  • ASTM B653 — pipe fittings, ensuring tightness and reliability of connections in complex systems.
  • ASTM B658 — specialized tubes for the chemical industry, designed for extreme operating conditions.
  • ASTM B752 — cast billets, serving as the basis for the production of complex parts with high precision.
