the rim area of the copper crusher. The copper crusher is then removed and the indentation measured (Fig. 6). The indentation must measure 0.014 inch (read to the nearest 0.0005 inch) with only a 0.001-inch variation to indicate a passing indentation test. Copper Used in the Crusher Both variations of the copper-crusher measuring system (to

8 MIL (.008 inches thick) 32 gauge: The 8 mil copper is approximately 11 - 12 times thicker than typical aluminum foil and 1.5 times thicker than the 5 mil. This is a heavy-duty tooling foil. 8 mil can be cut fairly easily with scissors and is still very pliable. It may hold shape a little better than the 5 MIL, but will not bear much weight and will yield to …

Copper crusher gauges are the traditional means to routinely determine peak pressures in large caliber weapons. Most attractive in this method is its simplicity in use. Questionable is the precision in reading the pressure in view of the cumbersome gauge calibration practice which is prone to errors, especially in the low temperature regime.
