(Specification)Standard Specification for Brass Plate, Sheet, Strip, And Rolled Bar
Standard Specification for Brass Plate, Sheet, Strip, And Rolled Bar
SCOPE
1.1 This specification establishes the requirements for brass plate, sheet, strip, and rolled bar of the following alloys:
Nominal CompositionCopper Alloy Previously Used Copper, %Zinc, %UNS No.DesignationC210001955C2200029010C22600. . .87.512.5C2300038515C2400048020C2600067030C2680086634C2720096337C28000. . .6040
1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combing values from two systems may results in nonconformance with the standard.
