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.
