Istanbul stands at the crossroads of European and Asian industrial manufacturing, acting as Turkey’s primary node for electronics, defense systems, automotive assemblies (TAYSAD), and heavy machinery. For procurement managers and thermal engineers working in industrial parks across Gebze, Tuzla, İkitelli, and Hadımköy, selecting a heat sink supplier requires a balance between metallurgical alloy purity, extrusion ratio precision, surface anodizing durability, and supply chain speed.
In high-power industrial electronics, such as solar string inverters, variable frequency drives (VFDs), and EV fast-charging stations, thermal management failure directly correlates with semiconductor degradation and component lifespan reduction. As power densities increase, purchasing managers are moving away from stock distributors toward direct mill-to-market heat sink extruders capable of delivering high aspect ratio fins, structural flat base plates, and fully certified alloy compositions.

Different industrial clusters within the Marmara region demand tailored thermal geometries and alloy tempers. Here is how our heat sink solutions integrate into local high-tech hubs.
Gebze Organized Industrial Zone is Turkey’s powerhouse for renewable energy electronics. High-capacity string solar inverters operating in Turkey's continental climate require extrusions made from 6063-T6 alloy with high thermal conductivity (~201 W/m·K). Our wide-base heat sinks feature integrated mounting channels and deep fin structures, ensuring maximum passive natural convection and preventing IGBT thermal throttling during peak summer ambient temperatures exceeding 40°C.
The Automotive Suppliers Association of Turkey (TAYSAD) cluster in Kocaeli/Istanbul requires compact liquid cold plates and liquid-cooled heat sink profiles for DC fast-charging stations (150kW-350kW). Utilizing 6061-T6 and 5083 alloys, our custom friction-stir welded (FSW) heat sink assemblies and skived plate bases isolate coolant lines while maintaining low thermal impedance ($R_{th} < 0.05 \text{ K/W}$) across power module contacts.
The Tuzla Shipyard and Pendik defense corridors build radar, communication, and electronic warfare systems requiring compliance with stringent military specs. We supply 5083-H116 marine-grade plates and AS9100/ISO 9001 certified CNC-machined 7075-T6 heat sinks finished with MIL-A-8625 Type III Hard Black Anodizing. This delivers elevated surface emissivity ($\varepsilon \ge 0.90$) and superior resistance against salt-spray corrosion along the Marmara coastline.
To support Istanbul’s booming 5G network expansion and enterprise data centers in İkitelli OSB, thermal management systems must offer lightweight, high-performance cooling. Our thin-fin extruded aluminum heat sinks with forced-air ducted channels lower thermal resistance while significantly reducing overall cabinet weight compared to legacy copper spreaders.
As Turkish original equipment manufacturers (OEMs) expand export capacity into the European Union, thermal component procurement is undergoing significant technical transitions:
With a group history in metals established in 1972, HAQ Aluminium provides a vertically integrated manufacturing ecosystem that combines billet casting, precision extrusion presses, heat treatment ageing ovens, multi-axis CNC machining, and automated surface finishing under one roof.
Standard extrusions in 6063-T5/T6 for high conductivity, 6061-T6 for structural stiffness, 6082 for heavy load frames, and 5083/5754 marine plates.
CAD/CAM engineered die creation with 10–15 day turnaround. First-article samples accompanied by CMM dimensional inspection reports.
Spectrometric chemical analysis, Webster/Barcol hardness verification, cross-hatch coating adhesion testing, and thermal resistance validation.
Technical and logistical answers compiled by our application engineering desk for buyers in Turkey.
For standard air-cooled extruded heat sinks, Alloy 6063-T6 is the industry standard due to its high thermal conductivity (~200-201 W/m·K) and excellent extrudability for complex fin profiles. If the heat sink serves a structural load-bearing role in heavy machinery or automotive chassis, Alloy 6061-T6 is recommended (~166-170 W/m·K with significantly higher yield strength).
Anodizing creates a controlled aluminum oxide ($\text{Al}_2\text{O}_3$) surface layer. While bare mill-finish aluminum has a thermal emissivity ($\varepsilon$) of only ~0.05, a matte black hard-anodized surface increases radiation emissivity to over 0.90, dramatically improving thermal radiation dissipation in enclosed spaces. Furthermore, it protects the component against salt-spray corrosion along coastal zones.
Material is packed in export-grade seaworthy timber crates with interleaved protective films and moisture desiccant bags. Shipments are dispatched directly to Ambarlı Port (European side) or Haydarpaşa / Yılport (Asian side). All orders include Mill Test Certificates under EN 10204 3.1, Commercial Invoice, Packing List, and Certificate of Origin for Turkish Customs clearance.
Yes. All custom die designs and extrusion tolerances strictly conform to EN 755-9 and DIN 17615 standards, matching or exceeding Turkish Standards Institution (TSE) criteria. We accept DXF, STEP, or DWG CAD files and produce verified first-article samples prior to mass extrusion runs.
For custom heat sink dies, standard MOQ ranges from 500 kg to 1,000 kg per profile section depending on circumscribing circle size and press tonnage. For standard alloy plates and sheet stock, flexible batch sizes are available.
Extruded profiles undergo mechanical stretch-tension leveling immediately post-quench, followed by precision artificial T5/T6 precipitation hardening in controlled ageing ovens. For applications requiring optical flatness (e.g., IGBT mounting faces), base surfaces undergo secondary face-milling to achieve planarity tolerances within 0.05mm.
