This is silver (.999) coated copper wire. It is useful for all kinds of craft projects requiring silver wire, but at substantially less cost, with no loss of appearance, and similar working properties to solid silver wire. Unfortunately I have not as yet determined the class of the silver coating ( this is generally from referred to from A to E class, with A being equal to 1.25 percent by weight in silver, and E being 10.00 percent by weight silver), but due to the finesse of the strands (25 AWG, or 0.01790 inches), by necessity, the silver content should tend toward the higher end of the scale, because of the ratio of coating thickness to substrate. As both silver and copper are used in enameling, this should be eminently suited to filigree pieces. As these metals readily alloy (go into solution) care should be exercised if approaching liquidus temperature (~962c for silver and ~1085c for copper). As for the pictures; the colors are not indicative of the actual color of the wire which is silver, (the most reflective metal known, with a possible exception of Rhodium), not gold as it appears, we took dozens of photos, to no avail, trying to get a representative image. I apologize for this. At full diameter (0.3850 inches) there are 259 strands, this breaks down into 37 sub-strands of 7 individual wires each. I formed a simple ring from two of these smaller groups for a reference of scale. The ring is a size 12 1/2 men's. Technically the wire is referred to as: 7/37/25 rope. If there are any questions you have, please feel free to ask, and as always , thank you for your interest. I almost forgot, the price is per foot. Thanks again. P.P.S. also as always shipping is a flat four dollars regardless of how large or varied the order.
