Is extruded aluminium the RIGHT material for your heatsink project?

An aluminum heatsink is important to prevent overheating in electrical components. It can carry the heat away because of its conductivity. Without an effective heat sink, many electronic components, machines, or equipment will burn out.

Extruded aluminium heatsinks are widely used due to their good heat dissipation. You can find them in LED lighting, automobiles, wind power generation, construction machinery, air compressors, railway locomotives, household appliances, computers, and other industries.

Large-sized aluminium heatsink profiles are mainly used in the central air conditioning and transportation industry, and small-sized aluminium heasinks are used in electronics, precision machinery, and instrument industries.

  • The 6063 aluminum alloy has good thermal conductivity (160-180W/m·K).
  • Aluminum extrusion makes the production of heat sink easier and relatively low cost.
  • Aluminum extrusion is easy to process into complex shapes. There are many customized shapes of extruded aluminium heatsinks for an ideal heat dissipation effect. The shape of an aluminum heatsink extrusion could be comb shapes, tree shapes, fishbone shapes, round shapes, etc. Increase the surface area of the aluminium heasinks, and the heat dissipation effect will be better.
  • The surface of the extruded aluminium heatsink is mainly anodized (always natural silver clear anodizing or black anodizing) to improve the aluminum material’s corrosion resistance, wear resistance, and aesthetics.

The Benefit You Can Get From FONNOV Aluminum Heatsink Extrusions

extruded aluminum heatsinks-fonnov
  • No MOQ For Stocked Aluminum Heatsinks

No minimum order quantity is required for our stocked aluminium heatsinks. Selecting a similar size from us will help save your cost on the prototype. 

  • High-quality Tooling And Material For Production

FONNOV uses high-quality steel tooling to ensure that each side of the aluminium heatsink has high strength and toughness because each side has to withstand a large extrusion force. If there is a big difference in performance, it is easy to break.

FONNOV ALUMINIUM extrudes aluminium heatsinks with national standard aluminum billet. We don’t produce with scrap aluminum. The surface will be rough if using scrap aluminum.

  • Extra Service Of CNC Machining And Secondary Coating

Fonnov delivers your aluminum heatsink for direct use. We also manufacture machined aluminum plates for your aluminum heatsink enclosure.

How Does FONNOV Produce A Qualified Aluminum Heatsink Extrusion?

To produce a qualified aluminum heatsink extrusion, high-quality aluminum ingots, high-precision die and extrusion process are all required.

Many fins on heatsinks make the aluminum heatsink extrusion more difficult than others. How do we ensure getting quality aluminum heatsink extrusions?

  • The steel tooling dies used for aluminum heatsink extrusion should be better. There’re many fins on heat sinks, and each fin will be under great pressure, so we must make each fin very strong. The high quality of the H13 steel die will be reliable to prevent any fins from breaking.
  • Avoiding fins breaking is also the main target during heatsink extrusion. What we should do is a careful extrusion and reduce the extrusion pressure.
  • The heatsink die will be under several amending after each trial to get a perfect dimension. So the aluminum heatsink extrusion is generally with several times trials.

Stocked Aluminum Heatsink Extrusions

We have a large and wide range of existing dies of the aluminium heatsink and electrical enclosure. This can help to save more costs.

The existing stocks are mainly of round aluminum heatsinks(hollow or solid) and straight fins aluminum heatsinks.

If you are looking for a stocked aluminum heatsink with small quantity, select one from our list.

Aluminum Heatsink Extrusion FAQs

What is the max. width you can extrude?2022-11-25T08:30:44+00:00

The max. width that we can do depends on the exact profile shape. Please send us your CAD drawings for a brief check firstly.

The wider the cross-section, the larger the extrusion press is needed. Our largest capability is with width 500mm for some shapes.

Many construction companies will be concerned about the maximum width that an aluminum extruder can do. For example, the width of the aluminum formwork usually needs to be at least 300mm.
