commercial brass - is there a specification?
commercial brass - is there a specification?
(OP)
We are running into a number of manufactures that are spec'ing "commercial brass" as the material for fasteners. We've been able to get a loose chart of material composition (wide percentage ranges) for what they are calling "commercial brass" but no real standard from which it was derived.
any insight?
thanks

We got a great price from a Mexican supplier, but the stuff had a funny color, didn't braze real well, and left some odd byproducts in the brazing furnace. In pursuit of an unrelated problem, we had some assayed... >16 pct lead. No wonder it machined so well.
If you don't specify a standard, and/or don't check for what you do specify, you are the legitimate prey of unscrupulous suppliers.
