B111 / SB111 C71500 Copper Nickel Tube O61 Annealed, Cold Drawn Seamless Tubing For Evaporator
Overview
ASTM B111/SB111 C71500 (70/30 copper-nickel) seamless tube, cold drawn and O61 annealed, is a high-performance alloy tubing designed for evaporators and critical heat transfer equipment. Featuring balanced copper, nickel, and iron composition, it delivers exceptional seawater corrosion resistance, erosion resistance, and thermal stability.
O61 annealing ensures optimal ductility, formability, and stress relief, making it suitable for expansion, bending, and assembly. Widely used in marine, offshore, desalination, and power plant evaporators, it offers reliable performance under high-pressure and corrosive conditions.
Cold drawn seamless manufacturing ensures precise dimensions, uniform wall thickness, and superior structural integrity. This tube combines excellent heat transfer efficiency and long service life, ideal for demanding evaporator applications.
