Our Anodized Aluminum Jumprings are anodized in house at our sister company, Premier Anodizing & Metal Finishing. This assures that we will never be out of stock of a color and that we have control over our quality. However, the colors can change slightly from batch to batch. We use a spectrometer to get the closest color matches possible but there still can be some differences, this is normal in the anodizing proccess. Therefore, you should order enough jumprings to finish your project all at the same time.
Our Jumprings are anodized before they are cut so the ends are raw aluminum however with the coating thickness we use and with the thin blades we cut our Jumprings with, if you close the rings properly the seam can not be seen.
Anodized Aluminum Jumprings are lighter weight than Enameled Copper Jumprings. The coating is fairly hard but it can be scratched with steel.
The anodizing process we use is FDA approved for cookware. Premier Anodizing uses only organic dyes and is rated non-hazardous.
Our jumprings 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.
