ZYTC Alloy is an ISO 9001 and AS 9120B certified superalloy manufacturer and supplier, offering ASTM SB 466 UNS C70600 seamless tube at factory-direct prices with full material traceability and fast global delivery. ASME SB466 specification covers the requirements for seamless copper-nickel pipes and tubes in straight lengths, including UNS C70600 (90/10 copper-nickel), C70400, C71500, C71000, C72200, and C71520. Copper-nickel C70600 is also known as Copper-Nickel 90/10 (10% nickel) and is recognized under ASTM B466 and ASME SB466. This alloy is known for its moderate strength, excellent weldability, and good formability. The inclusion of controlled quantities of iron and manganese provides extraordinary resistance to general corrosion, stress cracking, erosion, and impingement caused by turbulent water containing air bubbles and silt flowing at high velocities.
