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	Латунь, nickel-plated brass	Brass engraves cleanly; nickel plating requires fine-tuned settings.
Automotive Keys	Латунь, сталь, or aluminum; sometimes coated	Steel needs higher-power fiber lasers; coatings may need removal first.
Decorative / Novelty Keys	Алюминий, нержавеющая сталь, plastic tops	UV lasers excel on coated or plastic parts; MOPA fiber works for color marking on metal.

3. Choosing the Right Engraving Technology

When engraving keys, your choice of лазерный гравер matters. Different machines excel with different materials:

CO₂ Laser Engravers

• Not ideal for deep metal engraving

Волоконные лазерные граверы

• Лучшее для: Латунь, нержавеющая сталь, nickel-plated brass, алюминий
• Can engrave deep or perform color marking (with MOPA fiber lasers)
• Perfect for locksmiths or industrial marking

УФ лазерные граверы

• Produces ultra-fine detail with minimal heat impact
• Great for intricate logos or QR codes on keys

💡 Рекомендация:

• For all-metal keys (латунь, сталь, алюминий): ComMarker B4 or B6 MOPA Fiber Laser
• For plastic-coated or decorative keys: КомМаркер Омни 1 УФ-лазер
