12/20 Yellow Gold-Filled Half-Round Wire, 1/2-Hard

This 1/2-hard, 12/20 yellow gold-filled half-round wire offers a flat surface that makes it great for wire-wrapping on flat components and helps makes soldering more effective while presenting a round profile in your designs. The wire is great for creating loops, links and jump rings that have a flat inner surface. 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. 20-gauge wire is a good all-purpose weight; it is useful for head pins, jump rings, cuff and wire bracelets, neck wires, ear wires, earring posts, rivets. As you know, jewelry wire has as many uses as there are jewelers and designers who use it to achieve their vision; these suggested uses simply represent some of the more common applications of this metal weight. This gold-filled wire is packaged on spools, but may be coiled upon request (10-ozt. maximum per coil). It can be cut to any length that satisfies the system minimum. Orders must weigh at least 0.01 ozt.; if you click 'Add to Cart' for a quantity less than this, the cart will offer a prompt to let you know what the minimum for this item is. Gold-filled materials allow you to design and fabricate using the desirable color of karat gold while preserving a more affordable price point than is possible with solid gold. Its economical cost allows a greater latitude for trying out new designs or creating lines of fashion jewelry items.
