Yield strength		nearest ksi [nearest MPa up to 10 ksi, incl, nearest 5 MPa over 10 ksi]
Elongationnearest 1 %

 
1. Scope

1.1 This specification establishes the requirements for welded copper-nickel alloy pipe for general engineering purposes. The following alloys are covered:

Copper Alloy
UNS No.

Type of Metal

C70600

90-10 copper-nickel

C70620

90-10 copper-nickel

(Modified for Welding)

C71500

70-30 copper-nickel

C71520

70-30 copper-nickel

(Modified for Welding)

1.2 Units—The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems could result in nonconformance with the specification.
