High Performance Copper Alloy ASTM B466 UNS C70600 2.0872
What is ASTM B466?
This specification establishes the requirements for seamless copper-nickel pipe and tube in straight lengths， suitable for general engineering purposes. The alloys involved are copper alloys UNS Nos. C70400， C70600， C70620， C71000， C71500， C71520， and C72200.
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.
