Mastering the Art of Aluminum Cutting
Aluminum is everywhere – from aircraft wings and electric vehicle battery trays to building facades and heat exchangers. Its lightweight, corrosion‑resistant, and highly conductive properties make it indispensable. But cutting aluminum is not the same as cutting steel. Its reflectivity, thermal conductivity, and tendency to form a burr require a laser cutter designed for the task.
YIHAI’s aluminum sheet metal laser cutting machine is purpose‑built to overcome these challenges. With anti‑reflective protection, optimized piercing parameters, and nitrogen‑assist cutting, our machines produce clean, burr‑free edges on 1xxx, 5xxx, and 6xxx series aluminum – without damaging the optics or the material.
Why fabricators choose YIHAI for aluminum:
Anti‑reflective cutting
stable processing of reflective aluminum alloys (5052, 6061, 1100).
No edge burr
nitrogen cutting eliminates the oxide layer and produces a smooth finish.
Minimal heat input
preserves the material’s temper and mechanical properties.
Wide thickness range
from 0.5mm thin sheets to 20mm thick plates (depending on power).

Frequently Asked Questions
Q1: Can your laser cutter cut highly reflective aluminum (like 6061 or 7075) without damaging the laser?
A: Yes. Our machines include anti‑reflection protection (back reflection absorption) and dedicated piercing parameters for reflective alloys. Thousands of shops cut 6061 and 5052 daily with no issues.
Q2: What thickness of aluminum can a 3kW laser cut cleanly?
A: With nitrogen assist gas, 3kW cuts up to 8mm aluminum with a clean, burr‑free edge. For thicker plates (up to 12mm), you can use oxygen assist, but that may leave a thin oxide layer.
Q3: How do I choose between 1kW, 3kW, or 6kW for aluminum work?
A:
1kW – ideal for ≤4mm aluminum (thin enclosures, heatsinks, signs).
3kW – most popular for general fabrication (≤8mm aluminum, including 5052 and 6061).
6kW+ – for high‑volume cutting of 12‑20mm aluminum or faster speeds on thin sheet.
Q4: Will laser cutting affect the temper of aluminum (e.g., H32, T6)?
A: The heat‑affected zone (HAZ) is very small – typically less than 0.5mm. For most applications, the temper is preserved. For critical structural parts, we can provide samples for your testing.t.
Q5: Do you offer a sample cutting service on aluminum?
A: Absolutely. Send us a CAD drawing or a physical aluminum sheet (max 300x300mm). We will cut your part, take edge quality photos, and ship the sample back to you – free of charge.
Q6: What is the warranty on your aluminum laser cutting machine?
A: 2 years for the machine (excluding consumables) and 3 years for the laser source. On‑site service is available within 48 hours in major industrial regions.
