Create bold, durable jewelry with this 0.81 mm square 316L stainless steel wire, which is ideal for building metal structures.
With a diameter of 0.81 mm, this square wire is substantial enough to create shapes that need to retain their structure. Made of 316L stainless steel, it is stiffer than copper or brass wire of the same thickness and therefore requires more force when shaping. Its square cross-section accentuates its graphic appearance thanks to its flat faces and well-defined edges. This gauge is ideal for creating pendant frames, earring components, geometric shapes, or certain jewelry bases. It can also be used for structural wire wrapping, then complemented with a thinner wire for ligatures or to secure beads. For very tight, repeated wraps, however, opt for a smaller diameter.
How do you shape this 0.81 mm square wire?
Create a freeform shape, a frame,or a metal structure, then customize it with beads or a secondary wire. To learn different shaping techniques, check out this tutorial on shaping metal wire and creating earrings. Since the wire used in the tutorial is more flexible, adjust your technique to account for the stiffness of the stainless steel. You can also use this wire diameter for a ring project, drawing inspiration from this tutorial on rings with natural stones. Its square cross-section will give your design a more contemporary look.
