What is a C71500 copper nickel tube?
Copper Nickel tubes CuNi 70/30 30% or C71500 has the best resistance to acids corrosion compare with any other copper alloy tube. C71500 is used in harsh corrosive environments where longer service lives than those of other copper alloys are desired.
C71500 copper-nickel finned tubes is intergrally extexded for the maximum surface area to achieve high tube efficiency. Good C71500 copper-nickel finned tubes can be made by the strict conditions such as copper density, grain size and hardness. The heat transfer ratio of this high finned tube is about 8~9 times higher than other plain copper tube.
