Hi,
Red Brass is usually Cu, Sn, Pb & Zn, Semi-red brasses have a little more Zn.
Yellow brasses have from 58 to 72% Cu and as high as 40% Zn. Many of the
manganese and silicon bronzes contain Zn, up to 34%.
There are over 20 pages of Cu alloys listed in Machinery's Handbook, along
with all the screw pitch dimensions, etc, etc, etc.
If you are going to be building or modifying live steamers, you should
probably buy a copy. The price used to be around $60.00 for a new edition.
However, the older editions still have basically the same information, just
don't have the new fangled fasteners, etc. in them.
Wish I could say that I'd profit from your purchase, but sadly I'll remain a
"po-folk."
Keep your steam up!
Walt
