Take for instance 12-gauge thickness across the material types listed below; stainless steel is 0.105″ thick, aluminum is 0.080″, copper is 0.108″, and brass is 0.081″. Thickness Chart. You can use any number of calipers to measure the thickness of materials or a handy thickness gauge like one pictured below. Thickness Guage Tools


Sheet metal thickness gauges for steel are based on a weight of 41.82 pounds per square foot per inch of thickness. This is known as the Manufacturers' Standard Gage for Sheet Steel. For other materials, such as aluminum and brass, the thicknesses will be different. Thus, a 10 gauge steel sheet which has a thickness of 0.1345 inches will weigh ...


Although sheet metal thickness is most commonly measured by use of rolling mill strip gauges (either contact or non-contact) it may also be determined by bringing sheet metal samples to an adjacent dimensional measuring machine. Pratt & Whitney has several machines uniquely suited for material measurement: Plastic Film 1.


Thickness Measurement of Thin Conductive Layers. It is also possible to measure the thickness of a thin layer of metal on a metallic substrate, provided the two metals have widely differing electrical conductivities (i.e. silver on lead where s= 67 and 10 MS/m, respectively). A frequency must be selected such that there is complete eddy current ...


How to Measure Thickness (sheet form) STEP 1: Select whether the shape of the measurement target is a thin sheet or some other shape. STEP 2: Look at the methods outlined in each item to find the best measurement method. STEP 3: Download the relevant measurement system catalog.

The clad thickness measurement system is based on a magnetic technique that responds to the distance between the probe surface (which is placed on the clad surface or attachment weld surface) and the ferromagnetic steel base metal; this distance is equivalent to the clad or weld thickness.


Magnetic induction instruments measure the thickness of nonferromagnetic metal coatings such as chrome, copper, zinc, paint and powder coating over steel and iron. The amplitude eddy current method measures paint, powder coating, as well as anodize coatings over aluminum, stainless steel, copper and brass.


U.S. manufacturers express the thickness of metal panels as their ‘gauge’, with 22-gauge being the thickest and 29-gauge the thinnest of traditionally-sold metal roof and wall panels. Each gauge represents a nominal decimal range. ... a 26-gauge panel from another manufacturer could measure only 0.0179 in., but both are sold as 26-gauge ...


Measure nonferrous wiring with wire gauge measuring tools that specify measurements for these metals. Nonferrous metals do not contain iron. Push the wire into circular slots that appear close to the diameter. Use the gauge noted beside the slot that fits the wire snugly with no gaps.
