100 - 16 gauge Half Hard Copper Jump Rings - 6.7mm ID - 9mm OD - 1/4"
These Half Hard Copper Jump Rings are perfect for a variety of weaves. They are made from Solid Half Hard Copper Wire and they are perfect for medium - heavy duty projects. They come to you clearly labeled, freshly tumbled and free of burrs. They are ready for you to weave with them and then choose to solder them, oxidize them or leave them to naturally develop a classic copper patina.
These are great to work with because they are saw cut for nearly seamless closes and the size is made especially for chainmaille so they are easy to integrate into your weaves and designs.
Actual Size = 6.7mm ID - 9.1mm OD
ID = Inside Diameter
OD = Outside Diameter
Copper = CDA #110 alloy (99.9% Copper)
Suggested Uses = Sturdy Connectors
Actual Wire Size = 1.2mm
Mandrel Size = 1/4"
AR = 5.6
TAR = 5
AR = Aspect Ratio
TAR = True Aspect Ratio
16 gauge AWG (1.29mm) = 18 gauge SWG (1.22mm)
Why are the True Aspect Ratio (TAR) and the Aspect Ratio (AR) different? Because the AR is calculated on the Mandrel Size and the advertised Gauge Size - these both vary in the real world. The TAR is based on the actual accurate measurements of the jump ring diameter and wire thickness.
