Aluminum alloys in the 6000 series have good thermal conductivity, are widely available, and are fairly strong. They tend to extrude well too. The most common alloys for extrusion heat sink are 6061 and 6063. Our extrusion facilities can extrude in these alloys or in the alloy of your choice. Let’s know alloy and temper you prefer.

Our factory 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. Let’s know the anodizing you prefer.

One 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. Pins 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. Tell us about any secondary operations or machining your project may require. Please contact us.

Aluminum profile is pure aluminum or aluminum alloy as raw material, 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. 

Lori is a extruded aluminum heatsink manufacturer with a wide range of sizes and configurations for  extruded aluminum heat sink, many of which are actually industry standard. You can ask us for the  aluminum extruded heat sink you need. Even if you can't find a product that exactly matches your needs, we can work with you to design customized heat sink extrusion to meet your specific needs. Lori works with a number of top aluminum extruders in China that have years of experience in producing incredible products.

LED extruded aluminum heat sink is formed by aluminum extrusion, and by CNC machining, embedded in heat pipe, and finally finished by surface treatment. Led aluminum heat sink is liquid aluminium formed through a fixed mold. Then cut the led heat sink aluminum profile and mchined into the desired shape. The post processing cost is high, and the heat sink fin can be made very thin to increase the heat dissipation area.
