Wire Gauge Question

[Mark in Indiana]

Hello Friends,

I have a couple of wire gauges: a Starrett and an American Wire Gauge (see pictures). I noticed that on the American wire gauge, it has "non-ferrous metals". They look the same...so why does the American wire gauge have that stamping?


Thanks in advance.

For some reason, steel Guage is slightly different than non ferrous Guage. I seem to remember that it's slightly thinner for non ferrous, and not by a lot. Sheet metal Guage works the same way, where one is slightly larger than the other.

There are quite a few different Wire Gage standards.

This page shows just few of them.
