SPECIFICATION FOR SEAMLESS COPPER ALLOY PIPE AND TUBE

1.Scope

1.1 This specification covers seamless copper alloy pipein nominal or standard pipe size, both regular and extra-strong ,
and seamless tube in straight lngths for general engineeing purpuss.
Pipe and tube are commercially available in the following alloy:

Copper Alloy UNS No.A	previously Used Designation
C65500	High-Silicon Bronze A

A The UNS ysterm for copper anf copper alloys (se Recommended Practice E 527) is a simple expansion of the former standard designation system accomplished by the addition of a prefix"C" and a sufix "00." The sufix can be uesd to accmmodate composition variations of the base alloy.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
