Where to get Tellerium Copper?

Where can I purchase some 3 to 4" tellerium copper rounds? (Or any easily machined copper) I'm looking for some rounds 16 to 18" long. I expect they will be expensive

Can't provide you with any sources, but you'll have more luck searching for tellUrium copper than for tellErium copper.

Also -- consider the toxicity of it. It is not known to be as bad as beryllium, but it does have some known effects. From the web site:

====================================================================== Tellurium and its compounds are probably toxic and should be handled with care. Workmen exposed to as little as 0.01 mg/m^3 of air, or less, develop "tellurium breath," which has a garlic-like odor. ======================================================================

Also -- FWIW, the entry concludes with the following:

====================================================================== Costs: Tellurium costs about $100/lb, with a purity of about 99.5%. ======================================================================

I found this (and lots of other hits -- around 18,000) by running a Google search on "tellurium breath", which I remembered as an effect of the stuff. Some of the others suggest that once acquired, it lasts for months.

Enjoy, DoN.

I want to minimize the toxicity. (I realize that copper itself can be toxic)

I'm looking for easy to machine copper.

I'm told that machining pure copper is a bear.

I need the melting point and thermal conductivity of copper.

I'm going to machine away l away 95% of the 4" bar.

Any suggestions?

(I'm the same as the origional poster, just differn home/work account)

You bet your sweet butt I have a suggestion. Unless it won't fit your requirements, you should explore making your project from leaded phosphor bronze. It looks a great deal like copper, but machines wonderfully. Pay special attention to the part that says "leaded". Phosphor bronze without the lead is a bitch to machine, but it's the nicest material going once it has that small amount of lead added. For the amount of stock you have to remove, it would be a very good choice.

Have you checked the thermal conductivity of tellurium/copper alloy? I don't know what it is but do know that several copper alloys lose lots of thermal conductivity compared to pure copper. Pure copper is tough to machine, but if you only need one just use pure copper. If you need several maybe casting them work. ERS

on "tellurium copper" They have up to 2" dia.x 6' (2"x36" = $338.07) Call their customer service line. They may be able to put you onto a sourse or special order for you.

If you are going to machine away that much material, is there any possiblity of thinking in subcomponents that might be silver brazed together. I do this all the time to save on machining, material and time.
