Copper is softer than brass. In time, the copper will swage itself
loose. He would have been better off with brass or bronze canoe
brads. I have often used paper clips as rivets. Also the tap nails
for lady's spike heel shoes. Or nails from the hobby shop for making
plank on frame sailing ship models.
Knowing what acids and minerals can do to copper pipe, I wonder
what saliva would do to it.
7 out of 8 are slightly alkaline. The other 1 (me) are slightly
acetic. The ph factors are way too low to affect the metals. If your
ph were that high (or low), you would already be (for lack of a
better word) embalmed.
I thought of aluminum wire but I do not know if that would be
compatible with brass.
Alum is almost the worst thing you can put next to brass. Alum
develops a cottage cheesey corrosion and in a way, forms a weak
battery. Alum is not good around hostile moisture unless anodized ( a
2 system coating ..as oppopsed to a three system coating). . And that
usually doesn't work for long.
