Aluminum Extruded Profiles for Heatsink

Extruded Heat Sinks

The most popular and efficient type of heat sink is extruded heat sinks mainly created with aluminum. Available at a low cost with custom aluminum extrusion methods, the performance depends on the device and requirement.

Extruded heat sinks is also known as extruded aluminum heat sink, heat sink extrusion with beautiful appearance, light weight, good heat dissipation performance, energy saving effect. Simply put, aluminum heat sink extrusion technology is to heat aluminum ingots to 520~540℃ at high temperature, under high pressure to let the aluminum liquid flow through the heat sink extrusion mold with grooves, to make the extruded heat sink material. Then, after cutting and cutting the heat sink extrusion material, the extruded aluminum heat sink we often see is made. Aluminum heat sink extrusion technology is easy to realize, and the cost of equipment is relatively low, so it has been widely used in the low-end market in previous years. AL6063 is a commonly used aluminum heat sink material, which has good thermal conductivity and machinability.

1. Feature:

Base on aluminum extruding technology, we extrude out the profile first, then do the machining work like cutting,de-burring, CNC milling, drilling, tapping, polishing, surface finishing treatment, assembling, packing, etc.

2. Advantage:

1). More efficient and more cost-saving than mechanical processing;

2). There are a variety of standard shapes and sizes;

3). Good thermal performance.

3. Capability: 

Max. extrusion size: W550*H150mm.
