ASTM B134/B134M-01

Standard Specification for Brass Wire

SCOPE
1.1 This specification establishes requirements for round, hexagonal, octagonal, rectangular and square brass wire of UNS Alloys C21000, C22000, C22600, C23000, C23400, C24000, C26000, C27000, and C27400.
1.2 Units—The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text and tables, the SI units are shown in brackets. The values stated in each system may not be exact equivalents: therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.

B
Copper Alloy UNS No. C21000 in these several OS (annealed) tempers is too soft for Rockwell F hardness tests below 0.030 in. [0.75 mm] in thickness.
C
The nominal grain sizes are those in which wire other than rectangular are normally available. Rectangular wire is normally available in any of the nominal grain sizes
listed.
D
Although no minimum grain size is required, the material must be fully recrystallized.
