Who can explain in detail the comparison of heat dissipation modes of LED aluminum extrusion, die casting, stamping, ceramics and plastics? Thank you! !

Aluminum extrusion and die casting are basically the same except for different technology and cost. First of all, ceramics have high cost, good engineering and special mechanical properties and good heat dissipation effect. Stamping parts are general, plastic. . . I don't know. . . I've never seen plastic as a cooling material except for fans. Generally, aluminum and aluminum alloys are widely used in heat dissipation, and aluminum extrusion and die casting should be the most widely used in industrial technology.
