ASTM B75 / B75M

This specification establishes the requirements for seamless round, rectangular, and square copper tube suitable for general engineering applications.The values stated in inch-pound units are the standard except for grain size values which are given in SI units. This specification is the companion to SI Specification B 75M; therefore no SI equivalents are presented in this specification.
