Brass Coils Brass Coils
We use Jewelers Brass (alloy C226). It looks very similar to yellow gold when its not tarnished!
The strength and corrosion properties are similar to yellow brass – jeweler’s brass is about 8% stronger and costs a bit more.
Brass tarnishes but can be cleaned with an ultrasonic cleaner or any commercially available brass cleaner - like Brasso.
Most brass wire you will find is soft, but our brass is 1/2 hard temper which combines strength with workability.
We used to carry yellow brass and some products are listed as yellow brass. They will be converted to jewelers brass exclusively once our yellow brass wire is out.

We offer a taylored selection of sizes for brass 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.
