Grade 70/30 Cuni is what is referred to as 70% copper, 30% nickel alloy. Apart from copper and nickel as its primary alloyants, the alloy includes additions of iron and manganese. These elemental additions make the 70/30 Copper Nickel Flanges somewhat more resistant to corrosion as well as /erosion. Moreover, the tensile strength property of 70/30 is slightly improved as compared to grade 90/10. Thereby making Grade 70/30 Cuni well suited for more demanding applications. In particular, the corrosion resistance property of a Copper Nickel Alloy 70/30 Slip On flange is notably improved in high-velocity waters as well as polluted seawater. Commonly used with stub ends, a Cu Ni 70/30 Lap Joint Flange is regularly used for applications that require frequent dismantling.

A blind flange does not have a centre hole, and they are used to either blind or seal a pipeline, a valve/pressure vessel or to block the flow of the fluid. 70/30 Cuni Blind Flange has the ability to withstand remarkable mechanical stress on account of the system pressure and the required bolting forces. On the other hand, a 70/30 Cupro Nickel Spectacle Flange is a safety device that is used to isolate a section of line or piece of equipment, especially in instances when the line or equipment needs to be either inspected or removed from service.
