Brass with less than 15% zinc

[RJT]

How will C22000 or C23000 machine compared to 360 brass? Quoting on a job that has a lot of milling and turning, and I've never machined either of these 2 alloys. Or is there something else I should be looking at? Spec only says brass with less than 15% zinc.

"The machinability rating of this alloy is 30. (Where Alloy 360 FC Brass is 100)"

Stated for C22000, same for C23000

The lack of lead will have more to do with the more difficult machinability rating than the lower number on zinc. 360 brass is about 3% lead. I could be wrong but that is my guess.
