Copper Nickel 70/30 (C71500) L type finned tubes

What is copper Nickel 70/30 (C71500) L type finned tubes?

Copper Nickel 70/30 L type finned tubes are widely used in various industries for their excellent corrosion resistance, high thermal conductivity, and mechanical properties. 

The copper-nickel alloy, also known as C71500 or 70/30 copper-nickel, is composed of 70% copper and 30% nickel, along with small amounts of iron and other elements. This alloy offers exceptional resistance to seawater corrosion, biofouling, and erosion, making it ideal for applications in marine environments.

L type finned tubes feature fins that are shaped like an "L" and are typically created by wrapping a strip of fin material around the base tube. This configuration provides a large surface area for heat transfer and is commonly used in air-cooled heat exchangers and similar applications.
