ASTM B-467 / ASME SB-467
SPECIFICATION FOR WELDED COPPER NICKEL PIPE

1.Scope

1.1 This specification corvers weled copper-nickel alloy pipe for general engineering purposes. The following alloys are covered:

Copper Alloy UNS No.A	Previously Used Deignation	Nominal Composition. %
Copper Alloy UNS No.A	Previously Used Deignation	Copper	Nickel
C70600	706	90	10
C71500	715	70	30

The UNS system for coppe and copper alloys (see Recommended Practic E 527) is a simple xpansion of the former standard designation system assomplished by the addition of a prefix "C" and a suix "00." The sufix can be used to assommmodate composistion variations of the base alloy.
