Ideal for creating jump rings, pendant bails, ear wires, loops and a myriad of components that embellish other findings as well as a wide variety of techniques
Metal that is 1/2-hard is partially work-hardened and will hold its shape under some stress; ideal for forming structures that will support other components
Keep in mind that hardness is changeable (by annealing or heat-hardening) and is relative among metal types (each temper will feel and handle differently from one metal to another). When finishing your pieces, also keep in mind that the harder the metal is, the brighter a finish it will take.
