What is a C70600 copper nickel tube?
C70600 copper-nickel alloy pipe, belonging to the 90/10 copper-nickel system, possesses long-term stable corrosion resistance and good mechanical properties in marine environments and chlorinated media. With the 90% copper and 10% nickel combination as its core, C70600 copper-nickel alloy pipe is widely used in chemical, seawater treatment, and petrochemical fields, emphasizing a balance between physical properties and chemical stability. Through compositional control and heat treatment optimization of C70600 copper-nickel alloy pipe, a balance between strength and ductility can be achieved under different operating conditions, meeting the requirements of high-temperature applications demanding corrosion resistance.
Standards for C70600 Copper Nickel Tubes
The production and use of C70600 copper nickel tubes typically adhere to the following international standards:
ASTM B111/B111M: This standard specifies seamless copper and copper alloy condenser and heat exchanger tubes.
ASTM B466/B466M: This standard covers seamless copper-nickel pipe and tube.
EN 12451: This European standard pertains to copper and copper alloy tubes for heat exchangers.
EEMUA 144: This is a British Engineering Equipment and Materials Users' Association standard, specifically for copper-nickel tubes in offshore and marine applications.
MIL-T-16420K: This is a United States military standard for copper-nickel tubes.
