I would love to answer your question with total accuracy, Without additional information for right now, I can answer only according to my personal 'traditional wire wrapping' techniques. I do not believe in using any type of soft or dead soft wire to make bracelets unless you are sculpting, and then only in certain areas. (Bracelets are in a 'high traffic' area and need to be a strong piece of jewelry). My students, faculty members and I use half-hard square wire for 95% of our bracelet designs. (We are also known for taking the designs of other patterns and changing the designer's chosen wire to reflect our preferences, with great results!)
Most bracelet patterns can be made using either 21 or 22 gauge, square half-hard wire, including the all-important, cannot slip or slide, wraps! For a more masculine bracelet 20 gauge is a heavy, strong choice. Most bracelet designs that call for using a half-round wire for the wraps can be altered to use a square half-hard.
