The advantage of Copper Nickel Flange

Copper Nickel Flanges

We can offers ISO certified copper nickel flanges, stores large quantity Cu-Ni 90/10 Weld Neck Flange, Blind Flange and Threaded Flanges, Slip On Flange

Copper Nickel is mainly composed of Copper and Nickel, and Contains Small amounts of other Elements. It has beautiful Yellow Appearance because of the large amount of Copper. The most popular Copper Nickel are UNS C70600 and C71500. UNS C70600 Flanges contains 90% Copper and 10% Nickel, so it also called Cu-Ni 90/10 Flange. C71500 Flange is 70/30 Copper Nickel Flange.

We offer full type range C70600 flanges including Weld Neck Flange, Socket Weld flange, Threaded FlangeBlind flange, Slip on Flange,Lap Joint Flange and Spectacle Blind Flange.

Advantages of UNS C70600 Flange

ASTM B466 UNS C70600 Flange is stable and reliable at any temperature. It has good strength at moderate and elevate temperatures. At low temperatures, it maintains good mechanical properties, weld ability and high resistance to hydrogen. The great resistance to stress and erosion, excellent fabrication, high tensile strength, accurate dimensions make it largely used in seawater, aerospace, oil, chemical and gas industries.

Forged Flanges Manufacturer

Compared to casting flanges, forged flange have fine internal organization, better mechanical performance and ability to withstand higher pressure. The mainly manufacturing process of copper nickel flanges are as follow:
