Extruded Aluminum Honeycombs Revolutionizing Structural Core Materials

Specialist manufacturers employ precision extrusion to create aluminium honeycomb cores with consistent cell geometry. These advanced materials achieve densities between 25-130 kg/m³ while exhibiting exceptional compressive strength parameters from 1.8 to 15 MPa depending on alloy composition. The extrusion process creates continuous longitudinal cells with wall thicknesses ranging from 0.03mm to 0.2mm, providing 10-15% higher shear strength compared to expanded counterparts.

Unparalleled Engineering Properties

Extruded aluminium honeycomb structures deliver performance metrics surpassing traditional materials:

• Compressive strength-to-weight ratio exceeding 45 kN·m/kg
• Thermal conductivity values between 1-10 W/(m·K) depending on cell orientation
• Acoustic attenuation capabilities achieving 15-30 dB reduction across 500-4000 Hz frequencies

Military standard MIL-C-7438 testing verifies impact resistance 400% greater than polymer cores. Aerospace applications leverage extruded honeycombs for wing structures where FAA-certified panels withstand 7,500 psi compression loads. Recent technological advancements enable manufacturing tolerance control within ±0.02mm across continuous production runs exceeding 200 linear meters.
