Best Copper Bonsai Wire

Copper holds more for its thickness than aluminum does, which is why conifer work leans on it. A thinner copper wire can do the job of a fatter aluminum one, so less metal sits on the branch and the styling reads more cleanly. Copper also work-hardens as you bend it, stiffening in place as you apply it. It is sold annealed and soft, and how well it was annealed changes how pleasant it is to use. We weighed softness on application against stiffness once set, along with gauge accuracy and how the wire behaves when pulled from a tight roll. Annealed copper suits pines, junipers and anyone moving heavier branches. It is less forgiving on thin deciduous bark and harder to take off, so plan to cut it away rather than unwind it, and remove it before it starts to bite into the bark.
