Supplies: Sterling (prices, stats, ring counts) - Base Metal (prices, stats, ring counts) - Anodized Aluminum - Anodized Niobium - Enameled Copper - Tools - Kits/Instructions - Findings - Sale 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 Number = Wire Gauge Wire Gauges Conversions 24g = 0.5 mm (0.021") 22g = 0.6 mm (0.025") 20g ALUM = 0.76 mm (0.03") 20g all other metals = 0.8 mm (0.032") 18g Most ALUM = 1.19 mm (0.047")* 18g all other metals = 1.22 mm (0.048") 16g = 1.6 mm (0.062") Base Metal Jump Ring Sample Sheet (PDF) * As part of our efforts to standardize our ring sizes, we are switching our 18g ALUM to 1.22 mm to match the wire diameter of all the other 18g base metals. We have just started this switch as of late September 2008. We will try to keep this page updated frequently so you can see which sizes have the new 18g (for example, see D18 stats.

Please note! Stats listed in parenthesis are older and may or may not match current stats. During the fall, we are continuing to update as many stats as possible. 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.)

AAA24 24g 1/16 24g 1.6 mm	Metal	Aspect Ratio	Recommended uses
	SSTL	2.9	Euro 4-1 -- If you have the dedication to make a patch of Euro 4-1 with these size rings, I highly recommend it. Very smooth and fabric-like. Byzantine (2 connectors) Turkish Round

AAA24 prices

B22 22g 3/32 22g 2.4 mm	Metal	Aspect Ratio	Recommended uses
	ALUM	(4.2)	Euro 4-1 Japanese 12-2 (with F20 or G20 or H20) Note that aluminum is weak in this gauge, and so the rings should be doubled whenever possible for strength.
	BRSS	(3.9)
	BRNZ	(4.1)

	SSTL	4.1

B22 prices

B20 20g 3/32 20g 2.4mm	Metal	Aspect Ratio	Recommended uses
	ALUM	3.0	Doubled Japanese 6-1 (12-2), with F20 — Note that this is tight in copper and jewelry brass; it works well for 2-rows and japanese flowers (for wider pieces, use B22 & F20, or B20 & G20) Jens Pind for some metals —possible with the steel rings, but the AR is just a tad too loose, so with time, some of the rings pop out of place. Jens Pind is very stiff with the Copper rings. These rings also come in handy for jewelry repair that includes small chains or jump rings.

D20 20g 1/8 20g 3.2mm	Metal	Aspect Ratio	Recommended uses
	ALUM	(4.2)	Euro 4-1 Box (flat) Half Persian 3-1 Byzantine (3 connectors) Open Round -- works with SSTL, but may be too tight with other materials, especially BRNZ and COPP Mobius/Wiggle Japanese 6-1 (with N16) Japanese 12-2 (with L18) -- also works with other 18g, such as J18 and H18 Dragonscale (with H20) -- not all D20s work with all H20s. SSTL H20 with COPP D20 is probably too stiff to weave.

D18 ALUM uses new 18g ALUM wire.

D18 18g 1/8 18g 3.2mm	Metal	Aspect Ratio	Recommended uses
	ALUM	2.8	These rings work great at clasp points. The inner diameter is small, but the AR is low, meaning they are surprizingly strong. The kerf is large on the steel rings, so they are very hard to close. Jens Pind is possible, but tight. (With copper rings, the weave is not flexible).

	ALUM	3.3	Very snug European 4-1 (might be too tight in copper) Jens Pind (possibly too loose in steel) This ring has a low aspect ratio, meaning most weaves won't be possible. However, these rings are great for tiny rings at clasp points.
