Metals, Thickness & Tolerances

Metal Etching Process

ChemArt stocks many metals and alloys in numerous gauges and tempers. Some of the metals that can be etched using the PCM - Photochemical Machining Process - at ChemArt include:

Metal Etching ProcessBrass, Copper, Carbon Steels, Nickel, Kovar, Stainless Steel, Beryllium Copper, Phosphor Bronze, Inconel, Alloy 42, Nickel Silver, Invar, Monel, Tin, Mumetal, and various other exotic and electronic alloys.

Thickness and Tolerances

Metals can be 0.0005" (0.0127mm) to .0900" (2.286mm) thickness. The typical range is up to .0600" (1.500mm).

The standard tolerance is typically 10% of the thickness of the metal or alloy used to produce the part. See our Design Guidelines for more details.
