UNS C71500 Flanges


One of the outstanding features of copper-nickel is that the alloy has superior resistance to sea-water. The percentage of copper in 70/30 Copper Nickel Pipe Flanges is about 70%. The alloy’s resistance to seawater is attributed to the high content of copper. Singularly, copper has superior anti-microbial properties, when alloyed the material retains some of its properties. The addition of 30% nickel in the Cu-Ni 70/30 Slip On Flanges is the reason why the material is able to withstand elevated temperatures, while also exhibiting their good mechanical properties at said temperatures. Copper-nickel is an alloy that functions well when soldered, by forming a permanent bond. But in industries where the slightest spark can cause combustion, it is a safe option to use ASTM A151 Cu-Ni 70/30 Threaded Flanges. Another characteristic is that the alloy is easily cold worked, fabricated. Furthermore, the Cupro Nickel Werkstoff No 2.0882 SWRF Flanges could be welded without the necessity for any special considerations for the alloy. The superior ductility and malleability mean that the material can be used to produce different shaped flanges like the Werkstoff No.2.0882 Cupro Nickel 70/30 RTJ Flange. ordinarily used in high pressured applications, industries use UNS C71500 70/30 Copper Nickel Blind Flanges often fastening them with the help of bolts.
