What does wrot mean?
wrot, n. Building. Timber of which one or more surfaces have been planed smooth; wrought or dressed timber. I believe wrot (or wrought) has the same meaning for copper as wrought does for wrought iron, that is, it is worked, rather than cast, to it's final shape.

What does "wrot" mean in construction?
wrot, n. Building. Timber of which one or more surfaces have been planed smooth; wrought or dressed timber. I believe wrot (or wrought) has the same meaning for copper as wrought does for wrought iron, that is, it is worked, rather than cast, to it's final shape.
What books use the spelling wrot?
A Google Books search finds a couple of books published in 1987 that use the spelling wrot in labels accompanying line drawings of various plumbing fittings: James Kittle, Home Plumbing Made Easy: An Illustrated Manual and William Cooper, Commercial, Industrial, and Institutional Refrigeration. Not to assume anything about TAB Books and Prentice-Hall, the fine publishers of these two books, but I know from personal experience that certain publishers sometimes use labeled public-domain (that is, free) illustrations that may be quite old and may not reflect current spelling conventions. The labels in these two books appear to be in the same font and format, suggesting that the authors cut and pasted the labeled illustrations from the same source. I haven't been able to identify that source, however

What is the UNS number for copper alloy?
For example, Copper Alloy No. 377 (forging brass) in the original three-digit system became C37700 in the UNS System. The UNS is managed jointly by the American Society for Testing and Materials (ASTM) and the Society of Automotive Engineers (SAE). Because these old numbers are embedded in the new UNS numbers, no confusion need result.
