Walt,
It's new designation is C93200 but it's still commonly listed as 660.
Every mfgs's metal is going to vary slightly but the typical composition
of 660 is
Cu - 81-85%, Tin - 6-8%, Lead - 6-8%, Zinc - 2-3%
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
Hi,
You could try the do some de-zincification using common swimming pool acid --
HCl or often called Muriatic acid. Nitric acid is very dangerous to use, it
is a 'skin eater' acid. Muriatic does not eat your flesh, but the fumes can
be hazardous to mucous membranes, eyes, etc.
Put some small p
Harry,
What is the composition of SAE 660? On pages 2140 and 2141 of Machinery
Handbook 24 are listed 28 Bearing and Bushing Alloys. There are no numbers in
the 2xx, 3xx, 5xx or 6xx series for bushing bronze. Maybe I need to get a new
handbook. 24th Edition was in 1992. I must admit that there

Royce,
I'm in pretty much the same situation as I have lots of scraps of

Go to a local metal supplier(or even one of those really expensive

Hi group. I have an ingot of what I was told was bronze, from which I have been
making parts for my locomotives (axle boxes, cylinders, etc). But as I am now
going to need to make some boiler bushings, I want to make SURE that this
"bronze" has no zinc in it. (I got it indirectly from a person w
