hi .i love it . my e-mail is michael90210 AT hotmail DOT com
It will be good idea if some one add something related to mechanical properties of brass like compressive and tensile yield stresses.
Thank you
Sarvesh S.S.
Good article. I'd like to see a section addressing the most common and/or most important uses of brass in industry today. Also, a section breaking down the most important centers of brass production (assuming there are any). Just a suggestion. Thanks.

[edit] Brass vs. Bronze
This article seems to imply that, while some brasses are called "bronze", this is incorrect:
Some types of brass are called bronzes, despite their high zinc content.
On the other hand, the bronze article indicates that "bronze" is a general term for copper alloys, and therefore includes brass:
brass, a subset of the bronze alloys in which zinc is the principal additive
I am not qualified to judge which of these is correct, but they seem to contradict each other.

- Note: This issue has been resolved - the bronze article has been reworded (a subset of copper alloys) to resolve this. Spenny 08:22, 19 October 2005 (UTC)
Lead- With all the RoHS initiatives underway in the electronics industry, the question came up- is there ever lead in brass, or bronze? No indication in the article. Thanks- Doug
[edit] Brass VS Bronze cost
Dear editor,
Is there an appreciable difference in cost for Brass as compared to Bronze? What would be the basic difference? Is there a "rule of thumb" when it comes to pricing one verse the other e.g. a standard ratio?
Thanks

'Bold text'Bold text== Brass Chemicla composition and his impact on Mechanical Properties. ==
Can some address the relationship of composition of Brass to Mechanical properties. Chemincal properties
Cu Zn Pb AL Si Sn Fe and othrers
and what would be the impact on mechanincal properties? Mechanical properties. Hardness Tensile Strength UTS Elongation Etc..
Or can some body tell me the source?

show the density of brass. i need it for my sceince project. thank you.
[edit] Uses
Aside from decorative uses such as doorknobs, why is brass used? For example, it seems to me that brass bushings and valves are common. —BenFrantzDale 20:43, 9 January 2006 (UTC)
Probably a lot has to do with that it looks like gold (not exactly, but close) and is a hell of a lot cheaper.--CB319 04:21, 13 August 2006 (UTC)
Some companies preach the benefits of brass for use in car aerials. Does anybody know if there is any real reason or benefit offered by this material. reduced resistance for example.
[edit] Friction
It also might be mentioned friction for a brass on brass contact is low as metal-to-metal contacts go.
[edit] History
I was hoping to find much more about history here... I have read that, while brass-like alloys were in use for specialized purposes, brass didn't come into common use until after 1600. I suspect, if true, that has something to do with the availability of zinc, but that's just a guess at this point. Some references to bell-metal and (the original meaning of) gunmetal might be helpful. Rtimwest 13:04, 31 December 2006 (UTC)
[edit] brass
Is brass a homogeneous or a heterogeneous mixture? It's an alloy. But somewhere it said not all alloys are homogeneous mixtures. What makes the difference?
don't relaly know where to post this but i have alink to the brass phase diagram. might be useful to put on page but i dont know how.

[edit] COPPER in BRASS as a Disinfectant
On UK radio (Radio 2) today (14th March 2007) they have just announced that one hospital is testing the effectiveness of using a small piece of copper on door handles to act as a disinfectant that kills the super bug MRSA amongst others. Does anyone know if the copper content in brass is equally effective at killing germs and viruses? If so replacing all door handles with brass would seem an obvious solution to the spread of germs from touching door handles!

- Brass is slower, but still effective and advisable, according to this copper industry brochure http://www.cda.org.uk/antimicrobial/pub-182-naturally-antimicrobial-alloys-for-touch.pdf Femto 13:32, 14 March 2007 (UTC)
