1 1/2" Diameter Plain Flat Round Discs. 18 gauge which is .0478" Metal Thickness (approx. thickness of a dime). 1/16" is (.0625") thickness so this disc is slightly thinner than 1/16" Metal Steel Plates Circles. Cold Rolled Blank. A magnet will adhere to this disc.
After production several hundred pieces at a time are put into a mixer and tumbled for several hours. The tumbling process deburrs (smooths out) the edges and gives the metal discs a distressed look. Next the discs are sprayed lightly, tumbled some more, and then air dried for several hours.
