Quick Selection Guidelines
- Bare aluminum/iron sheets and cans always choose fiber laser for permanent high-contrast marking.
- CO₂ laser only works on pre-coated metal surfaces, not bare metals.
- UV laser is rarely used for metal marking except for special ultra-fine marking needs.
- Fiber laser is the industry standard for all metal packaging and industrial components.
- Metal marking requires high absorption rate of 1064nm wavelength - only fiber laser provides this.
