Aluminum sheet for laser engraving

In the field of precision manufacturing, laser engraving has strict requirements on the thermal conductivity, surface adaptability and processing economy of materials. Aluminum sheet has become the preferred material in the industry due to its efficient energy absorption, compatibility with multiple processes and light weight and high strength. Which aluminum sheets are suitable for laser engraving? What are the characteristics of each aluminum sheet? What are their respective application areas? This article will lead you to explore the full brand analysis and application guide of aluminum sheets for laser engraving.

Classification of aluminum sheets for laser engraving

• 1 series aluminum sheet: 1060 aluminum sheet, 1100 aluminum sheet

1060/1100 aluminum sheet is a low-cost and high-precision choice, with a purity of ≥99%, a thermal conductivity of 237W/(m·K) and a hardness of HV60-80. It has excellent ductility, and the surface roughness after oxidation is ≤0.8μm; the processing speed is the fastest (2000mm/s) and the material cost is low. It is suitable for electronic signs, crafts, and interior decorative panels.

• ‌ 3 series aluminum sheet: 3003 aluminum sheet, 3004 aluminum sheet

3003/3004 aluminum sheet is a model of balanced performance, containing 1.0-1.5% manganese, 30% higher strength than 1 series, and thermal conductivity of 160W/(m·K).Its oxide film is uniform and dense, and the engraving contrast is increased by 40%; it has strong fingerprint resistance and is suitable for electronic product LOGO and high-end instrument panels. It is suitable for consumer electronics, medical equipment, and building curtain wall logos.

• ‌ 5 series aluminum sheet: 5052 aluminum sheet, 5005 aluminum sheet

5052/5005 aluminum sheet is an outdoor weathering expert, containing 2.5-5.0% magnesium, salt spray resistance>1000 hours, and oxide film hardness HV400.It has extremely strong corrosion resistance and an outdoor service life of more than 10 years; the processing hardening characteristics make the engraving edge sharp (angle error <1°), suitable for industrial-grade components. Suitable for ship namesheets, traffic signs, and outdoor equipment identification.

• ‌ 6 series aluminum sheet: 6061 aluminum sheet, 6063 aluminum sheet

6061/6063 aluminum sheet is the king of structural engraving, containing magnesium and silicon elements, and the strength after heat treatment reaches aviation grade (tensile strength ≥ 310MPa). It supports deep engraving (＞0.5mm), and the substrate has strong deformation resistance; color anodizing process (red/blue/gold, etc.) expands high-end decorative applications. Suitable for aerospace parts, automobile VIN codes, and precision instrument structural parts.
