NOTE: This is a really old (and admittedly ugly) page. However, many customers have requested it, so here it is! I don't expect to be maintaining it; please proceed with caution.
  
         Here are stats and recommended weaves for the Base Metal rings. We're working on filling in the gaps on the chart. In the meantime, if you need stats for a particular ring size, just let us know. NOTE: Different gauge systems are used for different metals, so H18 SILV does NOT equal H18 in base metals. (Learn more in the Ring Sizes article in FAQ.)
   
      
         | Ring Names: Letter = Inner Diameter

 | Wire Gauges Conversions 24g = 0.5 mm (0.021")
 22g = 0.6 mm (0.025")
 20g ALUM = 0.76 mm (0.03")

Please note! Aspect ratios listed in parentheses are older and may or may not match current stats. Certain ARs may change, as we move toward standardizing our sizes. Our goal is for metals within a size to have as close an AR as possible to one another, despite springback and slightly different wire gauges for different metals. (For more, please see the March 25 entry in the supplies updates section.) The 20g ALUM is an exception; it will always have higher ARs than other 20g, because the wire diameter is slightly smaller.

 Jens Pind is possible, but tight. (With copper rings, the weave is not flexible).
