Analyzing the thermal dissipation demands within Gyeonggi-do, Incheon, Ulsan, and Pangyo Techno Valley under South Korea’s national high-tech manufacturing initiatives.
South Korea’s aggressive expansion in semiconductor mega-clusters (such as the Yongin Semiconductor Cluster) and electric vehicle (EV) supply chains has fundamentally redefined thermal management requirements. Modern Silicon Carbide (SiC) and Gallium Nitride (GaN) power inverters, high-bandwidth memory (HBM) packaging testing rigs, and 5G/6G telecom infrastructure generate heat fluxes exceeding 150 W/cm²—surpassing the dissipation thresholds of conventional air-cooled extruded profiles.
As a leading OEM/ODM heat sink manufacturer and global exporter, HAQ Aluminium bridges the gap between raw extrusion capability and high-precision CNC finishing. Korean Tier-1 automotive and semiconductor equipment integrators demand thermal solutions that comply strictly with Korean Industrial Standards (KS D 6759 for aluminum extrusions) while adhering to stringent RoHS, REACH, and ISO 9001/AS9100 requirements.
Tailored OEM/ODM thermal solutions custom-engineered for Korea’s primary industrial sectors and key economic zones.
Thermal test sockets, wafer chamber heat spreaders, and burn-in board heat sinks milled from AS9100-certified 6061-T6 and 7075-T6 aluminum plates requiring sub-micron surface flatness (Ra < 0.8 µm).
Liquid cold plates and high-power SiC inverter thermal housings for electric vehicle power distribution units (PDUs), onboard chargers (OBCs), and battery thermal management assemblies.
High-density 1U/2U server heat sinks, 5G Remote Radio Head (RRH) thermal enclosures, and active skived-fin copper-aluminum composite assemblies for hyperscale infrastructure.
Heavy-duty extruded aluminum profile heat sinks (up to 600mm width) designed for industrial solar inverters, ESS battery cabinets, and high-voltage power conversion equipment.
Selecting the optimal alloy temper and fabrication route based on thermal conductivity, mechanical strength, and corrosion requirements.

|---|---|---|---|---|
| AL6063-T5 / T6 | 201 - 209 | 200 - 240 | Excellent Extrudability | Standard Extruded Fin Heat Sinks, LED Drivers, Solar Inverters |
| AL6061-T6 | 167 - 180 | 290 - 310 | Superior CNC Machining | Liquid Cold Plates, AS9100 Precision Parts, Structural Coolers |
| AL1050 / AL1060 | 225 - 231 | 75 - 105 | Soft / High Ductility | Stamped Heat Fins, Ultra-Thin Thermal Shims, Spreader Plates |
| AL5052-H32 | 138 - 150 | 210 - 260 | High Corrosion Resistance | Outdoor Telecom RRH Enclosures, Marine & Battery Housings |
| AL7075-T6 | 130 - 140 | 540 - 570 | Ultra-High Strength | Aerospace Thermal Test Fixtures, Military-Grade Electronic Frames |
Founded on over five decades of metallurgical mastery, HAQ Aluminium operates an integrated manufacturing infrastructure that unifies billet casting, extrusion pressing, CNC precision machining, friction stir welding, and surface treatment under a single stringent quality management umbrella.
Direct technical and commercial answers regarding compliance, lead times, customization, and export logistics to South Korea.
For high thermal conductivity and intricate fin geometry, AL6063-T5/T6 is the premier choice, offering a thermal conductivity of up to 209 W/m·K. For structural cold plates requiring deep CNC milling or thread tapping, AL6061-T6 provides optimal mechanical shear strength and dimensional stability.
Yes. All raw aluminum billets and surface treatment processes (including anodizing and powder coating) are 100% compliant with EU RoHS 3.0 and REACH environmental directives. Material Test Reports (MTRs) and SGS hazardous substance lab reports are provided with every export shipment to satisfy South Korea's customs and KC verification requirements.
New custom die tooling typically takes 10 to 15 working days, including initial sample extrusion and CMM dimensional approval. Upon sample sign-off, mass production requires 15 to 20 days. Ocean freight from our facility to Busan or Incheon Port adds approximately 12 to 18 days, ensuring predictable delivery cycles.
Absolutey. We provide complete turnkey OEM/ODM solutions—including precision cut-to-length extrusion, CNC high-speed milling, drill tapping, deburring, thermal pad interface application, and surface color anodizing—allowing Korean line integrators to bypass local secondary processing costs.
We offer black anodizing (which significantly enhances surface thermal emissivity in passive convection environments), clear anodizing, hard coat anodizing (MIL-A-8625 Type III) for severe industrial exposure, and specialized electrically insulating ceramic coatings for high-voltage power supplies.
MOQ generally ranges from 500 kg to 1,000 kg per extrusion profile, depending on the circumscribing circle diameter and die press tonnage required. For high-value CNC machined cold plates or prototype runs, flexible batch sizes can be arranged during the technical review phase.
Accelerate your next-generation electronic, automotive, or semiconductor cooling project with precision-engineered aluminum extrusions and CNC cold plates.
