Specifications:

• Type: Double Layer (E-type – Oxygen Cutting)
• Aperture (Diameter): 0.8 mm – 6.0 mm (selectable options)
• Outer Diameter: 28 mm (D28)
• Thread: M11
• Height: 15 mm (H15)
• Material: High-quality copper

Available Sizes:

0.8 mm · 1.0 mm · 1.2 mm · 1.4 mm · 1.5 mm · 1.6 mm · 1.8 mm · 2.0 mm · 2.5 mm · 3.0 mm · 3.5 mm · 4.0 mm · 4.5 mm · 5.0 mm · 5.5 mm · 6.0 mm

Key Features:

• Double-layer structure ensures optimized oxygen gas flow
• Improved cutting efficiency and cleaner edge quality
• High concentricity for precise laser beam alignment
• Smooth internal channel reduces turbulence and slag buildup
• Durable, heat-resistant copper for extended service life

Applications:

• Compatible with fiber laser cutting heads (BOCI, Raytools, Precitec, WSX)
• Designed for carbon steel cutting using oxygen (O₂)
• Suitable for low, medium, and high-power laser systems

Recommended Usage by Diameter:

• 0.8 – 1.0 mm → Thin sheets (1–3 mm)
• 1.2 – 1.6 mm → Medium thickness (3–6 mm)
• 1.8 – 2.5 mm → Thick materials (6–10 mm)
• 3.0 – 4.0 mm → Heavy cutting (10–16 mm)
• 4.5 – 6.0 mm → Extra heavy-duty cutting (16 mm+)

💡 Note:

Double-layer (E-type) nozzles are specifically designed for oxygen-assisted cutting. They enhance gas flow dynamics, improving oxidation cutting performance and ensuring efficient removal of molten material when processing carbon steel.
