Cu-Ni Alloy 70/30 Pipes fittings
Cupronickel, commonly known as copper-nickel (CuNi) Pipes Fittings, is a copper alloy with nickel and reinforcing elements such as iron and manganese. Copper concentration ranges from 60 to 90 per cent in most cases. A typical alloy has a copper to nickel ratio of 3:1, with very little manganese. Cupro Nickel 70/30 Pipe Fittings have a mechanical density of 0.323 lb/in3 at 68 F. 2260 F melting point Tensile strength of 50000 psi, yield strength of 20000 psi (0.2 per cent offset), an elongation of 30%
Physical Properties of Cu-Ni Alloy 70/30 pipes Fittings
The colour of Cu-Ni Pipe Fittings is affected by nickel. As more nickel is added, the copper colour lightens. Alloys with roughly 15% nickel are almost silvery white. The brilliance and purity of the colour improve as the nickel concentration increases; at roughly 40% nickel, a polished surface can hardly be distinguished from that of silver.
Are Cu-Ni alloy 70/30 Pipes Fittings Magnetic
Pipe fittings made of Cupro Nickel 70/30 Pipe Fittings have a very low magnetic permeability of 1.01. The ease with which an external magnetic field can induce a magnetic force of attraction in metal is referred to as magnetic permeability.

Application in cupro-nickel 70/30 pipes fittings used
Cupronickel is utilised for pipelines, heat exchangers, and condensers in seawater systems, as well as for maritime hardware because it is very resistant to corrosion by salt water. It’s sometimes used for high-end boat propellers, propeller shafts, and hulls.
