Seamless Copper Alloy Tube ASTM B111 ----Copper & Copper Alloy High Fin Tube

Finned Tube----Copper & Copper Alloy High Fin Tube


The Copper & Copper alloy high finned tube is integrally extended 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.
