C36000 Brass- Brinell Hardness

[RITlab]

I am looking for the Brinell Hardness of C36000 (Free Machining) Brass that is Half Hard. I don't find it in the reference book or internet sites I use.

http://www.copper.org

lists Rockwell B hardness values for various sizes...dunno if you can convert RB to Brinell for brass.

You can compare but not convert

ASM HANDBOOK Volume 2 has hardness data (Rockwell B, HRB)for half-hard C36000. Some typical values for rod range from 75-80 HRB. Table 4 of ASTM E 140 shows approximate hardness conversions for cartridge brass (70Cu-30Zn) as follows:

75 HRB ~ 121 HB
80 HRB ~ 131 HB

copper.org also has the data from ASM HANDBOOK Volume 2.
