These are normally used for applications that require large-sized heat sinks. One benefit of these is that the base material and fin material can be different. Also, a combination of aluminum and copper fins can be used instead of just one fin material. This allows you to improve thermal performance while adding a minimal amount of weight. Bonded-fin heat sinks generally offer moderate performance and come at a high cost.
