Most of my plates are steel, I have done some in brass and one in copper. Man, I really dont like copper. What do some of you more experienced engravers think?
Forget copper! Buy Phosphor bronze it 1000x better than copper.
It does not oxidize overtime so your engravings will stay shiny.
It cuts beautifully nice long curls.
Bright cuts will be bright and stay bright. So you can show them to people without having first to remove the black layer like copper develops over time.
When practicing stonesetting the prongs are much stronger. Unlike copper where it is very easy to push a bit to hard and it breaks off.
Copper has been used by engravers as long as there have been engravers. Yeah, it can be gummy but it cuts beautifully and bright. I have copper sample plates that are over 100 years old with amazing engraving on them.
For me, I prefer mild steel. Cuts like a dream but it can rust of course.
Yes where did you get it? I have done searches for other types of bronze and the only thing I can find is rods, bars, and tubing. Many are for large orders for industry and not sold in square foot sheets.
I've engraved a bit of phosphor bronze back at New Orleans Arms Co because we had a ton of it used to make bronze castings. It cut really well but tarnished to a deep dark brown color. Not sure if all phosphor bronze is like that, but nowadays I'd use some GRS brass practice plates instead. They tarnish a bit, but nothing like that bronze.
Phosphorus is often added, as a deoxidizer, to Copper-tin alloys. Two common phosphorus bronzes (94.8 Cu, 5 Sn, 0.2 P) and (88 Cu, 4 Zn, 4 P, 4 Sn) can be enameled with the higher expansion enamels normally applied to copper.
