[edit] Please be more careful

I assume your intentions were good, but your recent edit to Copper added incorrect information. I have re-edited the article and provided a citation to support the value of 128GPA for bulk Copper. If you have information to support the value of 110 which you had inserted, please tell me on my talk page. Jerry lavoie 23:35, 22 February 2007 (UTC)

I added the number you had entered along with the citation you provided; both numbers are there now, as a range, as the other number had numerous sources for it, as well. Perhaps, if you are a student in this discpipline, you might be able to find a good reasoning for the disparity in these numbers, you might provide a brief description in the article. I suspect it has something to do with heat treatment, inclusions, work hardenening or other mechanical property affecting issue that the material each author was talking about; ie: one might be talking about raw copper as ored, and one might be talking about fully-annealed copper wire? Thanks. Jerry lavoie 13:47, 27 February 2007 (UTC)


Yes, I think the problem may be different copper types, I think thou for the main part of the Copper Element page should try to list it for pure copper, maybe if possible a section for copper alloys, I will use the resources I have to determine.
