Aluminum alloys in the 6000 series have good thermal conductivity which are widely available and are fairly strong. They tend to extrude well too.
The most common alloys for extrusion heat sink are AL6061-6 and AL6063-T5. Our extrusion facilities can extrude in these alloys or in the alloy of your choice.
We offer a range of finishing options. One of the most common surface finishes for heat sinks is anodizing. The anodizing electrochemical process increases surface emissivity, corrosion resistance, wear resistance, and electrical isolation. But coatings like paint or powder are not recommended, because they will act as insulators. Heat sink can be anodized at our extrusion facilities with colored dyes.
A way to help maximize the surface area of extrusion heat sink is by cross-cutting after extrusion. CNC machining is a very precise way to convert the fins on extrusion heat sink into pins. Pin fin heat sink help to maximize heat sink heat dissipation, making your heat sinks more effective. In addition, we can perform other secondary operations like drilling, milling, stamping, and cutting etc.
Advantages of aluminium heat sink
Aluminum profile is pure aluminum or aluminum alloy as raw material for heat sink, Various aluminum alloys include 6061, 6105, 6005, 6063, 6060, 6101, 1100 and 1350 alloys. The aluminum alloy after smelting, cutting, extrusion and other processes can form different section shape of the metal panel. And then can be cast in drawing, grooving, grinding, deburring, sandblasting, electroplating, radium screen printing, anodizing and other surface treatment processes can be fine surface, making heat sink enclosure with superior performance.
