More About Wire
Wire is an integral component to jewelry. Whether you’re wire-wrapping, creating coils, weaving or any other technique, the right wire choice will make your life easier. But, how do you know which wire to choose? Learn about how hardness, gauge and more can affect your end result.
Hardness
Dead-soft means it’s easy to bend and can be manipulated easily without tools. That’s it. These metals do not form hard or shape angles and will not hold shape well. It is good though for wire weaving, coils and spirals or wrapping around a harder base. This wire can be work harden, but if using coils, only the outer part will become hard, the inside of the coils will remain soft. Aluminum will always remain soft.
Full-hard is the exact opposite of dead-soft. This wire is difficult to bend and can be a bit brittle if bent too far. Full-hard wire retains its shape exceptionally well. Full-hard metal wire or sheet is often used as a frame or base. It is possible to soften full-hard metal by the process of annealing.
Half-hard is the sweet spot between the previous two tempers. This wire is fairly easy to bend, but it will retain its shape afterward. This particular hardness is the most commonly used wire for wire-wrapping, earwires, jumprings and hard angles. Half-hard metals can be made softer or work hardened to a full-hard temper.

| I mentioned work hardening But what does it really mean? As you work with metal, the more you manipulate it, the more rigid it will become. This process results in work hardening. On a more scientific level, you have moved the metal’s molecules closer together. It is best to work harden as much as possible before shaping, since it can become increasingly difficult to work harden after your piece is finished. While working on your piece, check the hardness often so your metal doesn’t become too brittle and break.Ways to specifically work harden include Pulling wire straight with nylon-jaw pliers or polishing cloth Tumbling with steel shot Hammer with a rubber mallet or jewelry hammer on a steel block Twisting Coiling and uncoiling Pulling through draw plates |
To soften up metal, you loosen the molecules up through the process of annealing. annealing is a process of heating and cooling resulting in more flexible wire. When annealing, metal oxidizes extremely quickly and a pickling solution is used to clean the metal to pristine quality again.
