Re <<But wouldn't the additive materials counter the cost savings? >> Material like nitride or graphite is fairly inexpensive. If you can get some directionality with heavily processed carbon fibers (high K's), then thermal improvements can be significant. Re <<You lost me on this one. Could you rephrase?>> In most application, the resistance of the heat sink is small compare to other thermal resistance. Think of two resisters in series. One is 10 ohms (resistance from heat sink to air), the other is 1 ohm (resistance of heat through the heat sink). Even if you reduce that 1 ohm resister to 0.5, you have done little in reducing the overall resistance. Mani
