3、ification establishes the requirements for copper-zinc-lead (leaded red brass or hardware bronze) rod, bar, andshapes of UNS Copper Alloy Nos. C31400, C31600, and C32000 available for general and screw machine applications.1.2 UnitsThe values Values stated in either inch-pound units or SI units are
4、to be regarded separately as standard. Within thetext, SI units are shown in brackets. The values in each system aremay not be exact equivalents; therefore, each system shall beused independently of the other. Combining values from the two systems may result in nonconformance with the specification.
