Copper Jump Rings- Specifications
Our copper jump rings are sold in one ounce bags only. These jump rings are solid copper, not plated copper. It starts the color of a shiny new penny but will darken or turn green over time. To clean copper, tumble or use an ultrasonic cleaner. Copper cleaners and polish will work also.
Our jump rings follow the American Wire Gauge (AWG), also known as Brown and Sharpe (B&S). All sizes listed are inside diameter (I.D.), which corresponds to the size of the mandrel onto which the wire is wound. Use these I.D.'s as a guide not an absolute as springback can occur.
The wire used to make our jump rings is of extremely high quality and made using an IOS-Certified production process. However, like all wire, there may be slight tolerances in size. Wire diameter may vary up to 0.03mm (0.0012”) larger or smaller than the listed size.
**Important Notice: Orders with more than 2 packs of an item may be bulk packaged at WGM's discretion. However, sizes will not be mixed in a bag.
