Aluminum Profiles for Radiators

Tongtoo specializes in the R&D and customization of aluminum profiles for radiators, serving as a specialist in complex structures and high-power heat dissipation applications. We integrate three core processes-precision aluminum extrusion, advanced CNC machining, and professional anodizing-providing a one-stop, customized heat dissipation solution from thermal design and prototype verification to mass production.

Precision Aluminum Extrusion: We develop molds with ultra-high fin width ratios (up to 20:1), using high-conductivity alloys such as 6063 and 6061, and incorporate multi-functional structures, such as fan shrouds and heat pipe grooves, in a single molding process.

Advanced CNC Machining: Installation surface flatness ≤0.03 mm, capable of complex feature machining and multi-component integration.

Professional Anodizing: Offering multiple color options, with salt spray test resistance of the oxide film ≥500 hours, combining heat dissipation optimization, electrical protection, and aesthetic durability.

Aluminum Extrusion: Maximum cross-section circumscribed circle Φ200 mm; fin width ratio up to 20:1; dimensional tolerance ±0.05 mm (precision grade).

CNC Machining: Positioning accuracy ±0.01 mm; flatness ≤0.03 mm/100 mm; surface roughness Ra ≤0.8 μm.

Anodizing: Film thickness 5–50 μm (customizable); customizable colors.

Covering new energy power systems (photovoltaic/energy storage inverters; on-board charger water-cooled plates), high-end industrial control (high-power servo drives; laser cooling systems), communication infrastructure (5G base station power amplifiers; data center cold plates), and consumer electronics and computing (high-end graphics card cooling modules, etc.).

Full-process quality control; ISO 9001:2016 certified; compliant with RoHS and REACH directives.
Equipped with comprehensive testing equipment and possessing global export experience. We provide collaborative design, customization, and full-process processing support, helping customers shorten supply chains and reduce costs.
