(2). Advantages of Aluminum heat sink

2.1. It has a thermal conductivity of 205W/mK, which is good (as a comparison: steel has about 50W/mK).

2.2. The production of aluminum heat sinks is inexpensive.

2.3. They can be made using extrusion.

2.4. Due to its softness, aluminum can also be milled quickly; die-casting and even cold forging are also possible.

2.5. Aluminum is also very light (thus, an aluminum heat sink will put less stress on its mounting when the unit is moved around).
