Copper Discs, 1/2-Hard

This 12.7mm, 18-gauge, half-hard round copper disc is ideal for shaping into components for your designs. The disc is die struck with clean, crisp edges and will require some finishing to smooth its edges and polish its surface. Use dapping techniques to create concave or convex designs; make round or saucer beads using matching dapped pairs of discs. It is a perfect foundation for other findings, including bezel cups or flat-bottom prong settings, as a backdrop for wire-wrapping designs, and for personalizing with engraving or design stamps. This stamping is ideal for enameling; when enameling on metal thinner than 20ga., it is important to use a counter-enamel on the back of the piece to prevent distortion or cracking of the enamel on the front surface. This disc has a 1/2-hard temper; it is partially work-hardened and will hold its shape under some stress. CDA #110 copper; 99.9% pure. Manufactured to exacting quality standards in our solar-powered facility.
