Explore our export-grade aluminium heat sinks, thermal mounting plates, and precision CNC-machined stock designed for optimal power electronics cooling, LED illumination, and industrial automation across the Philippines.
Thermal management in Metro Manila and surrounding industrial centers across Luzon presents a unique combination of thermodynamic hurdles. With average ambient temperatures frequently surpassing 35°C during peak dry season and relative humidity levels exceeding 85% in rainy months, electronic systems installed throughout PEZA (Philippine Economic Zone Authority) industrial parks face severe thermal throttling risks if not equipped with engineered heat sinks. Standard off-the-shelf cooling profiles designed for temperate climates routinely underperform in Metro Manila due to elevated ambient baselines ($T_a$), reduced boundary layer air convective velocity, and aggressive atmospheric salinity along Manila Bay.
When designing power electronics, variable frequency drives (VFDs), solar grid tie inverters, or outdoor telecommunications base stations for Philippine deployment, electrical engineers must calculate maximum junction temperatures ($T_j$) using higher thermal resistance thresholds ($R_{th}$). An un-anodized or improperly extruded aluminum heat sink loses convective and radiative efficiency rapidly when surface oxidation forms under humid conditions. HAQ Aluminium manufactures industrial aluminum heat sink profiles specifically formulated with high-purity 6063-T6 and 6061-T6 extrusion alloys, paired with military-grade matte black anodizing (MIL-A-8625 Type II) to maximize surface emissivity ($\epsilon \approx 0.93-0.95$) and sustain optimal heat dissipation under extreme tropical exposure.
The thermodynamic performance of an industrial heat sink depends fundamentally on alloy chemical composition, temper state, and grain structure alignment achieved during press extrusion. While pure aluminum (1000-series) offers high thermal conductivity ($\sim 220\text{ W/m}\cdot\text{K}$), its low yield strength renders it unsuitable for high-aspect-ratio fin profiles, structural mounting holes, or heavy thread tapping required in modern power modules. Below is our engineering selection matrix comparing primary heat sink alloys supplied to Manila electrical equipment original equipment manufacturers (OEMs).
| Alloy & Temper | Thermal Conductivity | Tensile Strength | Machinability & Tapping | Corrosion Resistance | Best Manila Application |
|---|---|---|---|---|---|
| 6063-T5 / T6 | 200 - 209 W/m·K | 200 - 240 MPa | Excellent for Extrusion Fins | High (Anodized Grade) | High-density fin profiles, LED high-bays, telecom enclosures |
| 6061-T6 | 166 - 180 W/m·K | 290 - 310 MPa | Superior CNC Milling/Drilling | Very High (Pitting resistant) | Structural liquid cold plates, heavy industrial VFD heat sinks |
| 6082-T6 | 170 - 185 W/m·K | 310 - 340 MPa | Excellent Structural Integrity | High Industrial Rating | Substation transformers, rail transit power converters |
| 5083-H116 | 120 - 140 W/m·K | 305 - 340 MPa | Good for Heavy Plate CNC | Exceptional Salt-Spray Marine | Manila South Harbor marine power drives, offshore enclosures |
Our advanced extrusion presses achieve fin-to-gap aspect ratios exceeding 20:1, maximizing surface area within tight spatial footprints in urban Manila equipment cabinets.
AS9100-certified multi-axis machining centers drill, tap, fly-cut, and face heat sink baseplates to flatnesses within 0.02mm, eliminating thermal interface voids.
Electrolytic deep-black and satin chromate finishes under automated temperature control guarantee consistent coating thickness and high radiant thermal emissivity.
HAQ Aluminium supplies custom and standard extruded heat sinks directly to contractors, original equipment manufacturers (OEMs), and system integrators operating in Manila's premier commercial and industrial corridors:
With large-scale solar installations expanding in Batangas, Pampanga, and Bulacan, grid-tie central inverters and string inverters operate under direct solar radiation. Our 6063-T6 heavy comb heat sinks with thick baseplates absorb transient heat spikes from IGBT modules, while integrated liquid cooling channels prevent power derating during peak Philippine afternoon sun.
The explosion of cloud data centers in Bonifacio Global City (BGC) and Makati requires high-density server rack cooling components. We provide skived-fin and high-aspect pin-fin aluminum heat sinks designed for high velocity forced-air cabinet cooling, alongside custom cold plates for direct-to-chip liquid cooling circuits.
Manufacturing plants in Laguna, Cavite, and Batangas rely on Variable Frequency Drives (VFDs) and servo controllers operating 24/7 in non-air-conditioned shop floors. HAQ Aluminium supplies drop-in replacement extruded comb profiles and custom machined heatsinks with pre-drilled mounting patterns matching major industrial drive footprints.
High-mast LED floodlights along the Manila Port Area and major highways require radial and pin-fin anodized heat sinks capable of withstanding constant exposure to salty sea air, sulfurous vehicle exhaust, and torrential monsoon rains without suffering surface pitting or thermal performance decay.
The industrial landscape of Metro Manila and greater Luzon is undergoing a rapid technological transformation driven by three key national initiatives:
A. The Philippine Green Building Code Mandates: Tightening energy efficiency regulations require commercial building HVAC systems, elevator traction drives, and power distribution units to achieve lower heat loss metrics. Higher performance aluminum thermal management systems directly contribute to lowering building Power Usage Effectiveness (PUE) ratios.
B. Growth of Semiconductor Assembly & Testing (OSAT): As Philippine semiconductor parks expand in Clark and Calamba, electronic test equipment manufacturers require ultra-flat, stress-relieved 6061-T6 aluminum plates milled to micron-level tolerances for thermal vacuum chambers and IC burn-in test sockets.
C. Adoption of Wide-Bandgap (SiC & GaN) Power Electronics: Next-generation power converters utilizing Gallium Nitride and Silicon Carbide operate at higher switching frequencies and higher power densities. This shift demands heat sinks with lower junction-to-ambient thermal resistance ($R_{th,j-a}$) and micro-channel liquid cold plate designs capable of managing heat flux levels exceeding $100\text{ W/cm}^2$.
Established in 1972, HAQ Aluminium represents over five decades of metallurgical expertise. Operating from a fully integrated manufacturing facility, we manage every step of production under one roof: from raw primary billet casting and extrusion die design to multi-axis CNC machining, automated anodizing, and strict quality assurance.
Unlike metal brokers or trading intermediaries, our factory-direct model provides Manila B2B buyers with complete lot traceability, custom die tooling turnarounds in 10-15 working days, and direct mill-test certificates (MTC) matching international ASTM and EN standards.
Standard sea freight transit time to Manila International Container Terminal (MICP) or South Harbor is typically 12 to 18 days. Production lead time for standard profiles is 7 to 10 days, while custom extruded dies require 10 to 15 days for die creation and sample approval before mass extrusion.
Yes. Our engineering department works directly with DXF, DWG, STEP, and IGES files. We conduct thermal extrudability analyses, verify fin-to-gap aspect ratios, design custom extrusion tooling in-house, and supply first-article inspection (FAI) samples prior to full production runs.
We recommend our sulfuric acid anodizing process (15µm to 25µm coating thickness) compliant with MIL-A-8625 Type II standards, or chromate conversion pretreatments paired with architectural polyester powder coatings. Our anodized 6063 and 6061 heat sink profiles pass ASTM B117 salt spray testing exceeding 1,000 hours without surface pitting or oxide growth.
Yes. We provide complete commercial documentation, including Mill Test Certificates (MTC to EN 10204 3.1), Certificates of Origin (Form E/FTA where applicable), commercial invoices, and packing lists structured to facilitate smooth PEZA tax-exempt customs clearance through Manila ports.
All high-power heat sink baseplates undergo precision CNC fly-cutting or face milling on multi-axis machining centers. Flatness and roughness are verified using optical CMMs and profilometers, guaranteeing baseplate flatness within 0.02mm per 100mm to minimize thermal interface material (TIM) thickness and thermal resistance.
MOQ for custom heat sink profiles depends on die size and press tonnage, generally starting from 500 kg to 1,000 kg per profile run. For standard stock extrusions, CNC-machined plates, or sample prototype batches, smaller quantities can be accommodated.
