ASTM B111 C71500 copper nickel alloy seamless tube is a Cu-Ni 70/30 alloy tube designed for condenser, heat exchanger, and marine engineering applications.
Manufactured according to ASTM B111/B111M requirements, C71500 tubes are produced as seamless copper alloy tubes for thermal equipment including surface condensers, evaporators, and heat exchangers.
C71500 copper nickel alloy contains copper as the base material with nickel alloying elements, providing a material option for applications requiring copper alloy tube characteristics in industrial and marine environments.
Standard: ASTM B111 / ASME SB111
Material Grade: UNS C71500
Material Type: Copper Nickel Alloy
Common Designation: 70/30 Copper Nickel
Tube Type: Seamless Tube
C71500 is classified as a 70-30 copper-nickel alloy, commonly used for condenser and heat exchanger tube applications under ASTM B111 specifications.
Typical composition characteristics of C71500 copper nickel alloy include:
| Element | Composition |
|---|---|
| Copper (Cu) | Balance |
| Nickel (Ni) | Approx. 29-33% |
| Iron (Fe) | Controlled alloy element |
| Manganese (Mn) | Controlled alloy element |
The exact chemical composition shall comply with ASTM B111 requirements.
ASTM B111 C71500 seamless tubes are manufactured through controlled production processes:
Copper nickel alloy billets are prepared according to material requirements.
The billets are processed into preliminary tube forms through extrusion.
Cold drawing is applied to achieve specified outside diameter, wall thickness, and dimensional requirements.
Heat treatment, straightening, surface finishing, and inspection are performed according to applicable specifications.
C71500 combines copper and nickel alloy elements to provide a suitable material solution for condenser and heat exchanger tube applications.
The seamless manufacturing method provides uniform tube geometry without longitudinal weld seams.
C71500 tubes are commonly used in equipment where copper alloy tubes are required for heat transfer systems.
