Brass 59-1A?

Brass 59-1A?

Brass 59-1A?

(OP)
I am working with a supplier in China that is using what they call a Brass 59-1A.  I have a composition material cert. sheet showing the following:

Cu  57.308
Pb  1.896
Al  0.352
Fe  0.496
Cd  0.0071
Zn  Balance

I have searched all over to find a comparable brass in a US standard, but have come up empty.  I am looking for material properties and something to hold them to.   Anyone heard of this designation?

Thanks

RE: Brass 59-1A?

How close do you need to be ? Isn't C37700 or C37710 close enough ??

RE: Brass 59-1A?

(OP)
I was basically looking for a US standard that this material is supposed to match so that I can hold them to it.  They replied with a standard of ASTM C37800, but the copper.org website says this was cancelled in 1992.  What exactly does this mean when it is cancelled?  It's still a standard that I can hold them to isn't it?
