Question
I was looking for copper sheets to conduct electricity and see soft and dead soft sheets. What does that mean? Thanks  Ed

Answer
1- Practically, most jewelry wire is sold now as either dead soft, half-hard, or hard, with dead soft being wire manufactured with a hardness of 0, half-hard being wire manufactured with a hardness of 2, and fully hardened wire being wire with a hardness of 4.
2- Dead soft wire is extremely soft and pliable. It can be easily bent and is excellent for making rounded shapes including a spiral. The disadvantage of using soft wire is that the finished piece can be bent out of shape if not properly handled.
3- Half-hard wire is slightly stiffer than dead soft wire. Half-hard wire is excellent for making tight, angular bends, for making loops in wire, and for wrapping wire around itself. Finished pieces made with half-hard wire are often more permanent than pieces made with soft wire. Half-hard wire does not do a good job of making spirals.
4- Hard wire is very stiff and tends to spring back after being bent. This can make it harder to work with when using a jig. Hard wire will not make a spiral. The advantage to hard wire is that the wire components made out of hard wire are difficult to make but very permanent.
