C71500 CuNi 70-30 Copper Nickel Flange

C71500 copper-nickel, also known as 70/30 copper-nickel, offers good corrosion resistance, especially in marine saltwater environments. The primary forged copper-nickel alloys selected for use in seawater service contain 10% or 30% nickel. They also have the important additions of iron and manganese, which are necessary to maintain good corrosion resistance. Although this alloy was known to the Chinese in the 9th century, it did not become popular until the 1920s when it was developed for use in the Navy's seawater condenser systems. It retains its strength well at moderate temperatures, has good cold and hot workability, and is easy to weld.

C71500 copper-nickel is used for brine piping and fittings, refrigerator and condenser components, welding wire and boiler components, brine flanges, heat exchangers and cooling units, welded backing rings, etc.
