ASME SB111 C71500, CuNi70/30 Copper Nickel Tube Seamless Tube For Heat Exchanger

Introduction

ASME SB111 C71500, also known as Copper Nickel 70/30, is a high-performance copper alloy tube with 70% copper and 30% nickel. It is renowned for excellent resistance to seawater corrosion, high thermal conductivity, and mechanical strength, making it ideal for marine and power industry heat exchangers and condensers.

Chemical Composition (per ASME SB111)

Element	Content (%)
Copper (Cu)	69.0 – 77.0
Nickel (incl. Cobalt)	29.0 – 33.0
Iron (Fe)	0.4 – 1.0
Manganese (Mn)	≤ 1.0
Zinc (Zn)	≤ 1.0
Lead (Pb)	≤ 0.05
Others (each)	≤ 0.05
Others (total)	≤ 0.15

Mechanical Properties (Annealed Condition)

Property	Value
Tensile Strength	≥ 303 MPa (44,000 psi)
Yield Strength (0.5% ext.)	≥ 103 MPa (15,000 psi)
Elongation (2")	≥ 30%
Hardness (HRB)	Typically ≤ 80

Key Advantages

Outstanding seawater corrosion resistance (even in turbulent flow)
Good resistance to stress corrosion cracking and pitting
Excellent weldability and formability
High thermal and electrical conductivity
Reliable performance under high temperature and pressure

Applications

Heat exchangers and condensers in power plants and chemical industries
