377 Forging Brass

[dshore]

377 forging brass can be purchased from manufacturer's all over the world. Has anyone noticed a quality difference between manufacturer's, or is forging brass the same no matter the producer?

Thank you.

dshore...

WHAT form/material spec for copper alloy 377, are You referring to?

ASTM? AMS? Mil-? QQ-B-?
Wire, Bar, raw forging stock, finished forgings?
Material Certs necessary?

From my limited knowledge, it would be raw forging stock in a round or hex shape. Typical use would be for valves for water distribution systems.

Thanks

As noted by WKtaylor, 377 forging brass is basically a generic description for a copper-based alloy. You need to include the appropriate specification in your purchase order for the specific raw material form, condition and quality your application requires. From your last post it appears that you likely require a specific size of bar stock that will work with your forging tool. And since you are using this material to make forgings, I would assume you want high quality raw material, such as wrought bar.

To further add: 377 is the old CDA designation for the alloy that is now called UNS/CDA C37700. This designation only specifies chemistry - nothing more. I have had the situation where material has been designated as 377, but was in fact non-conforming with a similar chemistry. I subsequently was informed it was an allowable substitution by my customer, but you do need to make sure you have certs at least for the chemistry.
