I've seen a lot of people use a piece of billet aluminum to draw the heat away from their work piece. Is billet aluminum better than normal aluminum for absorbing heat? Where can I find a nice size piece to clamp my work pieces to it?Torchmate 2x2 CNC with Flashcut CNC controlsHypertherm Powermax45 Esab ET220i Razorweld 195 MigRazorweld 200ac/dc TigTormach 770, Tormach xstechRazorweld, Vipercut/Vipermig, SSC Foot Pedal Dealer
Reply:I see them at the local scrap yard sometimes. Never the size I'm looking for though. I would think a Chicago scrap/salvage yard would have a lot. Igger variety than what my local one has. Here, scrap alumium costs $1.50/lbSafety 3rdGump
Reply:billet is no better than any other aluminum. Go to your scrap dealers and see if they have large pieces of heatsink material or large aluminum bus bars (calling electrical contractors can also be a source- they demo this stuff all the time and usually just scrap it)
Reply:Chunks of Copper flat bar are even better. It is even more difficult to find but it conduct heat better than aluminum. Industrial electricians often are involved in jobs where there is copper or aluminum bar for carrying very high amperages. Sometimes you are lucky but a scrappy will want top prices if they do have it. Yards in Seattle used to have quite a variety of large aluminum bar because Boeing was nearby. You might find heavier aluminum pieces in scrap yards near large aircraft manufacturers in your area.

Reply:There's no such thing as "billet" aluminum. There is only a billet of aluminum, generally meaning the large piece of aluminum that is going to be forged, drawn, etc. The type of aluminum is designated by it's alloy and temper.
Reply:Go on practicalmachinist.com and ask for billet aluminum, they know the best sources.

Reply:I bought a really nice 2X4X24 chunk from Online Metals for a really decent price recently, It has the advantage of knowing exactly what it is (6061-T6). It will chill just about anything you could clamp it to but only weighs a couple of pounds. Good luck on your most current quest for mzterials.BobI'm spending my Kids inheritance, I dont like him that much anyway!!!!!!Enuff tools to do the job, enough sense to use em.Anybody got a spare set of kidneys? Trade?
Reply:I bought a huge chunk from Online metals as well. I'm going to say 1.5-2" x 3" by about 5"? It was not scrap prices though I did pay retail prices but they are good with small quantities. I originally intended to machine it for a specific project, but now it's just a big chiller bar. I use it as a general weight to hold things down also. Or prop up things to roll to keep them from rolling - it's quite handy for that. I've even sanded a perfectly flat surface on one side, so I can wrap some sandpaper around it and use it to flatten smaller flanges that aren't perfectly flat. And it's even a good prop for my arm or hand when welding sometimes. It's actually quite handy.
