Aluminum or copper metal with good thermal conductivity, light weight, easy processing, and a few ceramic sheets can be applied to the surface of heating elements. It is currently one of the most common products for heat dissipation. 
It is a problem that related industries are (ALSO?) facing, how to improve the thermal conductivity and heat dissipation area for the improvement of heat dissipation efficiency. 
The methods of heat sink are stamping, extrusion, die-casting, and forging. These finished products can be used as the main components and mechanical parts for heat dissipation, and some are responsible for the dual tasks of mechanism housing and heat dissipation.
