copper aluminum heat sink

Aluminum alloys are the most common heat sink material. This is because aluminum costs less than copper. However copper is used where higher levels of thermal conductivity are needed. Some heat sinks use a combination aluminum fins with a copper base. Copper heat sinks are available on the market. They can be used in instances where higher thermal conductivity outweighs the available weight savings. Besides, significant cost savings can be had by producing heat sinks through aluminum extrusion. Most heat sinks are produced by this way. by Gabrian | Extruded Aluminum Heat Sinks, Aluminum Extrusion, Blog, Heat sinks Electronic devices
