ASTM B111 UNS C70600 Copper Nickel 90/10 Seamless Tube Heat Exchanger U Bend Tube
UNS C70600 (Copper Nickel 90/10) is one type of copper-nickel alloys, which has excellent corrosion resistance even in marine environments.
Primary Elements: Composed of approximately 90% Copper (Cu) and 10% Nickel (Ni).
Additional Elements: May also contain small amounts of iron, manganese, and other elements to enhance properties.
This alloy possesses average high strength and good creep resistance at high temperatures, and costs more in comparison to copper-aluminum alloys and other alloys with similar mechanical properties

Cupro Nickel Tubes 90/10 for Heat Exchangers & Condensers
These Cupro Nickel tubes & pipes for Heat Exchangers & Condensers are very important for all Industrial fields. The company has experience in these areas and is able to supply these tubes in accordance with most international standards and special customer requirements.
Cupro Nickel Tubes 90/10 for Automobile Industries
Copper had been proved since the early days to have many good attributes. It was easy to bend and had very high corrosion resistance, but there was concern about its low corrosion-fatigue strength. When copper-nickel was introduced, it displayed corrosion resistance similar to copper, higher general strength and better fatigue strength. Good formability allows ease of flaring and bending, and although the metal cost is greater than that of steel alternatives, copper-nickel is very attractive in view of its extra life, trouble-free installation and ety/reliability characteristics.
Applications
1. Aluminum Brass Tube for condenser and heat-exchangers.
2. Water Evaporators.
3. Boiler Blowdown Heat Exchangers
4. Air coolers.
5. Gland Steam Condensers.
6. Steam Ejector.
7. Turbine Oil Coolers.
8. Fuel Oil Heaters.
9. Compressed Air Inter and After Coolers.
10. Ferrules, Oil Well Pump Liner, and Distiller etc.
