Product Description

ASTM B111 C70600 Seamless Copper Alloy Tubes

Material & Chemical Composition

C70600 (CuNi10Fe1.6Mn) is a copper-nickel alloy with superior resistance to seawater corrosion and biofouling. Key chemical components include:

Element	Cu	Ni	Fe	Mn	Zn	Impurities
Content	Bal.	9.0~11.0%	1.3~1.7%	0.5~1.0%	≤0.5%	≤0.2%

Mechanical Properties

Property	Value
Tensile Strength	≥380 MPa
Yield Strength	≥170 MPa
Elongation	≥25%
Hardness	80~120

Key Advantages

Superior Thermal Conductivity: 50 W/m·K (3x higher than stainless steel), ensuring efficient heat transfer.

Saltwater & Corrosion Resistance: Ideal for marine condensers and desalination plants.

Anti-Biofouling: Inhibits microbial growth in cooling systems.

Seamless Manufacturing: Precision cold-drawn process guarantees uniform wall thickness and leak-free performance.

The finning is tight — you can tell they used a proper cold-forming process because the fins don't move at all when you try to wiggle them. We've had issues before with other suppliers where the fins would come loose after a few thermal cycles, but these ones feel solid.

It's genuine 321H — titanium-stabilized, so no worries about sensitization or intergranular corrosion during welding. Our welder said it welded nicely with no cracking.

Heat transfer has been consistent since day one. Our outlet temperatures are steady, and the exchanger is performing exactly as we expected.
