2. What Materials Are Keys Made Of?

The first step in engraving keys is understanding their material composition—this determines the best engraving method.

Key Type	Common Materials	Engraving Notes
Household Keys	놋쇠, nickel-plated brass	Brass engraves cleanly; nickel plating requires fine-tuned settings.
Automotive Keys	놋쇠, 강철, or aluminum; sometimes coated	Steel needs higher-power fiber lasers; coatings may need removal first.
Decorative / Novelty Keys	알류미늄, 스테인레스 스틸, plastic tops	UV lasers excel on coated or plastic parts; MOPA fiber works for color marking on metal.
