Crafted from 6063-T5/6061-T6 aluminum, these profiles feature high thermal conductivity, customizable extrusions, and surface treatments, ideal for electronics, LED lighting, and industrial machinery.
Thermal Performance Optimization
Fin Geometry: Variable fin thickness (0.8-3mm) and spacing (2-8mm) designed via CFD simulations, increasing surface area by 40% compared to generic extrusions (thermal resistance reduction ≥20%).
Alloy Selection:
6063-T5 (thermal conductivity 180 W/mK): Balances formability and heat transfer for moderate-power devices (≤100W).
6061-T6 (thermal conductivity 167 W/mK): Higher strength (yield 276 MPa) for heavy-duty applications (e.g., server racks, power inverters).
Precision Extrusion Technology
Dimensional Control: Profile tolerance ±0.1mm (ISO 2768-1 medium class), with straightness ≤0.5mm/m and twist ≤1°/m, ensuring seamless integration with heat sources.
Surface Finish:
Mill finish (Ra ≤12.5μm) for cost efficiency.
Anodised (20μm Type II) for corrosion resistance (salt spray 1000h) or black chromate (5μm) for EMI shielding (attenuation ≥20dB at 1GHz).
Customization Flexibility
Cross-Section Design: Supports complex shapes (U-shaped, L-shaped, serrated fins) with aspect ratios up to 20:1, including embedded heat pipe slots and mounting holes (M3-M8 threads).
Length Options: Standard lengths 1-6m, with custom cutting (±1mm accuracy) and end machining (chamfering, tapping) for direct assembly.
Installation & Maintenance
Lightweight Design: Density 2.7g/cm³, 50% lighter than copper heat sinks, reducing structural load in aerospace and portable electronics.
Low Maintenance: Anodised surfaces resist oxidation and dust accumulation, with optional hydrophobic coatings (contact angle ≥110°) for outdoor applications.
Electronics Cooling: CPU/GPU heatsinks in servers, gaming PCs, and industrial control panels, maintaining junction temperature <85°C under full load (JEDEC JESD51-1 compliant).
LED Lighting: Dissipates heat from high-power LED arrays in streetlights and stadium displays, preventing lumen depreciation (≤5% loss after 50,000 hours).
Renewable Energy: Cools inverters in solar/wind systems, with salt-resistant anodisation (ASTM B117, 1500h) for coastal installations.
Thermal Simulation Expertise
In-house ANSYS Fluent analysis optimizes fin parameters for target airflow (natural/forced convection), ensuring 15% higher heat dissipation than off-the-shelf solutions.
Certified Quality
Compliant with IPC-7251B thermal management standards and RoHS 3.0, with material traceability (Mill Test Reports) and 100% dimensional inspection via laser scanning.
Rapid Prototyping
3D-printed extrusion dies (lead time 7 days) for custom profiles (MOQ 50 meters), supported by in-house tooling capabilities for complex geometries.
Global Supply Chain
Stocked in standard profiles (e.g., 40x40mm, 60x30mm) for 5-day delivery, with automated packaging (anti-static bags, foam inserts) for international shipping (ISTA 3A certified).
