i need to make a couple of heat sinks for use inside round cro-moly tubing. i plan on taking round bar and split it in half long ways then use a couple of wedges to hold it securely against the ID of the tube. my question is what should i make them out of? aluminum is my first choice as it is cheap and readily available. but bronze and brass are also thoughts? any reason to use these more expensive materials? material is so any idea what material will be best for my heat sinks???
