The logical choice for rugged applications on long term durable goods would be metal nameplates and tags. Metal is very stable, heat resistant and abrasion resistant. It has the ability to hold a higher part tolerance and serve as structural support. Metal is the preferred material for fixed calibration or measurement devices such as scales, rulers or dials, since it insures accuracy and high durability of calibrations and markings. Other applications include information for long term product traceability, rating info, instructions, part reorder, sales, maintenance and Military specification.
