Description
CNC machined aluminum heatsinks are essential for efficient thermal management in industrial electronics. Crafted from high-quality aluminum alloy (6061/6063) via precision CNC machining, our heatsinks deliver exceptional thermal conductivity to keep electronic components cool. The anodized black surface not only boosts corrosion resistance but also ensures a sleek, professional appearance.
With a tolerance of ±0.05mm, these CNC machined aluminum heatsinks provide a precise fit for industrial devices, enabling seamless integration into assemblies. Each unit undergoes 100% dimensional inspection with calipers to guarantee accuracy. Whether you need standard sizes (such as length 100–300mm with customized width) or fully tailored heatsink designs, we offer a MOQ of 50pcs, sample lead times of 3–7 working days, and bulk deliveries within 10–15 working days.
Ideal for power supplies, LED fixtures, and other industrial electronic applications, our anodized black aluminum heatsink combines CNC precision with durable performance. Customization options for dimensions, fin geometry, and surface treatments make it easy to meet your specific thermal management needs.
Our CNC Machining Facilities & Capabilities
On delivery efficiency, we balance speed and precision: rapid prototyping takes 3-5 working days, small-batch production (50-500 pieces) is completed in 7-10 working days, and large-volume orders are delivered within 15-25 working days (adjustable based on order scale and complexity).

Quality Assurance
Incoming Check: Verify raw material certificates + sample tests (hardness, composition) to rule out defects.
In-Process Inspection: Spot-check critical stages with CMMs to validate tolerances (±0.001mm) early.
100% Final Test: Full dimensional, surface roughness, and functional checks—only passers move forward.
Outbound Review: Secure packaging + batch labeling; test reports/certifications included for traceability.
