Dead link

The "National Pollutant Inventory" external link is dead as of testing on 2010-Jan-13 20:41 EST. Page not found.

I have fixed the link. Wizard191 (talk) 17:04, 14 January 2010 (UTC)[reply]

I added the reference to the Suzuki Harmonica having Phosphor Bronze reeds - taken from their website. —Preceding unsigned comment added by 121.242.69.250 (talk) 08:04, 14 June 2010 (UTC)[reply]

Phosphor bronze —> Phosphorus bronze: Move page ? No, This title is correct

Question: would this page not better deserve the title of Phosphorus bronze ? I did a typo mistake somewhere else with oxygen-free copper containing Phosphor when an helping soul did correct it in Phosphorus. Or does this copper glow in the dark ? ;-) Cheers, Shinkolobwe (talk) 20:00, 26 June 2010 (UTC)[reply]

No, I think that is the normal name for this alloy, see here. Although that may be rather idiomatic. SpinningSpark 20:25, 26 June 2010 (UTC)[reply]
Thank you very much for this very useful verification. It was worth and I am happy not to have renamed that page. :-) Shinkolobwe (talk) 20:33, 26 June 2010 (UTC)[reply]

The difference in the colour

Is this due to the different content of components that the propellor is dark gray (no yellowish hue characteristical for copper alloys) and the saxophone is of 'normally' golden-yellow color? Thanks for Your answer in advance. --159.148.226.100 (talk) 19:39, 1 November 2010 (UTC)[reply]

I'm not 100% sure about this, but I believe the instruments are plated, while the propellers have oxidized. Wizard191 (talk) 20:01, 1 November 2010 (UTC)[reply]
Thank You! So the ancient statues are dark in consequence of oxidation, too? What about instruments, IMHO a section of this article says them having 'more reddish' and so on hue namely due to the different composition.
The following is from the saxaphone article:

After completing the instrument, manufacturers usually apply a thin coating of clear or colored acrylic lacquer, or silver plate, over the bare brass. The lacquer or plating serves to protect the brass from oxidation, and maintains its shiny appearance. Several different types and colors of surface finish have been used over the years.[18] It is also possible to plate the instrument with nickel or gold, and a number of gold-plated saxophones have been produced.[18] Plating saxophones with gold is an expensive process because gold will not stick directly to brass. As a result, the brass is first coated with silver (which will stick to it) and then gold-plated on top.

So it seems to me the color differences are from plating differences, not composition differences. The range of different compositions for phosphor bronze is relatively small, therefore I wouldn't expect to seem much color differences. Wizard191 (talk) 13:14, 2 November 2010 (UTC)[reply]
Just to clarify, the phosphor bronze instruments are lacquered, not plated. The color is the color of the unoxidized metal. — Preceding unsigned comment added by 75.111.20.66 (talk) 23:20, 15 December 2014 (UTC)[reply]

Cavitated propeller image

As a bronze foundry person (I have poured thousands of pounds of bronzes), I think the cavitated propeller is actually cast aluminum. Unless there is a substantiating piece of evidence that it is indeed phosphor bronze, the cavitated propeller image should be removed from the page. —Preceding unsigned comment added by 71.116.66.59 (talk) 06:56, 20 May 2011 (UTC)[reply]

I have removed it based on your comment. Wizard191 (talk) 18:24, 20 May 2011 (UTC)[reply]
