[edit] Brass is an alloy

Brass is an alloy consisting mainly if not exclusively of copper and zinc. The brasses may be conveniently divided into two groups according to their malleability, the dividing line being approximately the composition of 55 percent copper and 45 percent zinc.

Thank you

[edit] Misc

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.

Most house keys are brass coated in nickel, I guess its because its corrosion resistant, shiny and brass is easy to machine (customise)

It seems rather odd that such eclectic uses as cryogenics are mentioned, but not the near-universal use of brass in cartridge casing. 68.230.161.164 (talk) 04:33, 26 January 2008 (UTC)

[edit] Friction

It also might be mentioned friction for a brass on brass contact is low as metal-to-metal contacts go.

  • Agreed, brass is commonly used for its "self lubricating" properties. Kinema 09:55, 12 September 2007 (UTC)

[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] Saltwater effects on Brass

How does saltwater effect brass?

Thank you! Ckelley4 13:22, 4 March 2007 (UTC)

Random question, yet interesting. Brass is used in brass instruments; when these instruments are played, saliva will enter the instrument. So, since saliva is mostly water, and salt wouldn't be expected to react with brass, I don't think saltwater would affect brass. -68.4.73.34 (talk) 07:03, 26 December 2007 (UTC)

[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)

[edit] Proposed project

There is evidently no extant WikiProject which deals with articles concerning alloys and other chemical compounds. This could be a problem, as many of these articles deal with what are considered to be generally important topics. To correct this situation, I have proposed a project to deal with these articles at Wikipedia:WikiProject Council/Proposals#Chemical compounds and mixtures. Anyone interested in contributing to such a project should indicate as much there. Thank you for your attention. John Carter 20:34, 28 April 2007 (UTC)

[edit] How brass is made

Only one paragraph on how brass is made? And nothing on where in the world it is now primarily made. - Jmabel | Talk 00:19, 15 November 2007 (UTC)
