Comparative Gauges Of Sheet & Plate



The table below shows the thickness in inches of materials characterized by a gauge number in three different gauge systems.  Aluminum alloys are usually gauged according to Brown & Sharpe.  We have provided the comparative data as an aid to those who plan to substitute aluminum for ferrous materials and are working with specifications based on ferrous metal gauge numbers.
