Copper Coils Copper Coils
Our Copper is solid and not plated. It starts the color of a shiny new penny and can either darken or turn green depending on how it is used.
Our copper is hard temper. It is much stronger than the copper used for electrical wiring.

We offer a taylored selection of sizes for copper coils. The minimum amount you can buy is listed on the lower right of each wire guage product box below. If you need a smaller amount of a ring or you need a different size please browse our wide selection of rings.
Please read this before you decide to cut your own rings
Cutting rings requires special tools and setups and the costs to cut only a few rings are higher. I highly recommend you read the following 2 FAQ posts before deciding to cut your own rings
How to use a Jumpringer type tool (aka Pepe, Koil Kutter, etc)
Making vs Buying rings - Bottom line is we have a business making rings in large amounts at great prices. The vast majority of the time it doesn't pay to make your own rings - and you will get better cuts buying pre-made.
