Copper Nickel Fin tube ,C71500 High Fin tubes,Copper fin tube
These Copper & Copper alloy high finned tube is intergrally extexded for the maximum surface area to achieve high tube efficiency.
A good finned tube 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.
