Natural Anodized Aluminum Heat Sink

Product Overview

Our dense fin aluminum extrusion heat sink is manufactured from high thermal conductivity 6063-T5 aluminum alloy. The base production flow starts with aluminum extrusion forming, followed by precision cut-to-length and straightening. We support secondary CNC machining including milling, drilling, tapping, and grooving per customer drawings or samples. The surface finish is natural silver anodization, which improves corrosion resistance and maintains stable thermal performance. As a professional custom aluminum heatsink manufacturer, we accept OEM custom service to modify dimensions, fin structure, mounting holes, and surface treatment to match your thermal design requirements.

Technical Specifications
Product Name Dense Fin Aluminum Extrusion Heat Sink
Material 6063-T5 Aluminum Alloy
Overall Dimension 55mm (L) * 55mm (W) * 7mm (H)
Manufacturing Process Aluminum Extrusion → Precision Cut → Straightening; Optional CNC Milling, Drilling, Tapping
Surface Treatment Natural Silver Anodizing
Thermal Conductivity ~201 W/(m·K)
Machining Tolerance ±0.05mm for CNC secondary machining, ±0.15mm for extrusion profile
Fin Type Dense parallel fin structure for enlarged heat dissipation area
Applications
  • LED lighting modules and LED driver cooling
  • DC power supplies and switching power supply units
  • PCB electronic modules and semiconductor components
  • Audio amplifier circuit boards
  • Industrial control circuits and communication equipment
Custom & OEM Service

We are a professional manufacturer providing full custom and OEM service for aluminum extrusion heat sinks. You can send us your design drawings, samples, or thermal requirement parameters. We support custom size adjustment, fin density redesign, CNC drilling, tapping, milling, and alternative surface treatments. We can produce both standard off-the-shelf sizes and one-off prototype samples as well as mass production orders.

Key Advantages
  • Dense fin design delivers a larger heat dissipation area to solve insufficient heat dissipation for compact electronics
  • 6063-T5 aluminum with good thermal conductivity avoids overheating damage to core electronic components
  • Precision CNC secondary machining ensures accurate hole position and solves mounting misalignment issues
  • Natural anodized surface prevents oxidation and solves short service life problems in humid environments
  • Flexible OEM custom service meets non-standard thermal structure requirements that ready-made heatsinks cannot fit
Quality Control

All aluminum extrusion profiles are inspected after extrusion and straightening. CNC machined parts are checked by calipers and micrometers to guarantee tolerance compliance. We conduct surface visual inspection for anodized parts to reject scratches, blemishes, and uneven coating. Sample testing is available before mass production, and we keep production inspection records for each batch.

Shipping & Delivery
  • Sample order: 3–7 working days after drawing confirmation
  • Mass production order: 7–15 working days based on order quantity and custom machining requirements
  • Shipping options: express courier for small samples; sea freight or air freight for bulk shipments
  • Each heat sink is packed with protective foam to avoid scratches and deformation during transit
Frequently Asked Questions
Q1: Can you make custom size aluminum heat sinks besides 55*55*7mm?

Yes, we provide OEM custom service. Send your drawings or sample, and we will quote and produce accordingly.

Q2: What secondary CNC machining can you do on this aluminum extrusion heat sink?

We support CNC milling, drilling, tapping, countersinking, and profile trimming.

Q3: Can I get a prototype sample before bulk order?

Yes, sample production is available for your thermal performance testing.

Q4: Is natural anodizing the only surface option?

No, we also support other anodized colors and passivation upon request.

Q5: What is the tolerance for CNC machined features?

Our standard CNC machining tolerance is ±0.05mm for critical dimensions.
