Electromarking produces a sharp, attractive design or impression. The aircraft and defense industries prefer it because it does not cause distortion or sharp indentations in the metal. Also, manufacturers who produce quality cutlery, feeler gages, saw blades, and carbides like Electromarking for its clean, clear impression. In general, Electromarking is most applicable where hardened, or thin, or already assembled parts must be marked permanently with no distortion.
One can perform Electromarking on almost any bare metal (except painted or anodized surfaces). It isn't necessary to clean the surface before marking with any chemicals, but a lightly oiled surface may improve the mark. Most plated surfaces are also easily Electromarked.
