Solution
The answer is yes, there are better alloys. They cost many times more than 6061. If you need to dissipate more heat, the most economical solution is to use a bigger 6061 heat sink or go to copper.

Hello JohnA'
Thank you for your reply. Wiki also states the two alloys as you mentioned.
I thought there are even more than these two alloys.
