ASTM B151 C70600 Copper Nickel Threaded Forged Fitting B16.11
What is ASTM B151?
This specification establishes the requirements for copper-nickel-zinc and copper-nickel rod and bar for general application produced from Copper Alloy UNS Nos. C70600, C70620, C71500, C71520, C74500, C75200, C75700, C76400, C77000, and C79200.
What is UNS C70600?
UNS C70600 is one type of copper-nickel alloys, which has excellent corrosion resistance even in marine environments. 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.
C70600 Copper Nickel 10% Alloy is used in applications where
resistance to corrosion and stress cracking is important. C70600
Copper Nickel 10% Alloy is known for its moderate strength,
weldability and formability.
C70600 copper-nickel is an alloy of copper, further classified as a
copper-nickel (cupronickel). CW352H is the EN numeric designation
for this material.
