February 26, 200917 yr i just got the access to a good bit of carbide cutting tips for lathes and was wondering if they can be forged or not.
February 26, 200917 yr yup but your basic forge won't get it hot enough. Electric arc may. I would not bother trying. carbide is a broad term too.
February 26, 200917 yr Your "carbide" bits are very likely a metal matrix composite of tungsten carbide aggregate in a cobalt "cement." I very much doubt that you'll be able to forge them, but if they're free there's no harm in experimenting, is there? I can't guarantee that it's safe, though. You might want to look into that.

February 26, 200917 yr By the way, I don't know why IFI isn't registering my posts, but that wasn't my first. :)
February 27, 200917 yr from a quick search it looks to be 3100 degrees, but the article was about putting it under pressure 300 tons. I guess the benefit of carbide tips is that it is so heat resistant. http://www.jetpletters.ac.ru/ps/1377/article_20867.pdf
February 27, 200917 yr I was under the impression that carbide tips were a sintered material ie powder put under extreme heat and formed by ressure into required shape. Anyone know different?

They are. I'd like to see a cite for forge tungsten, the stuff is generally pretty impossible to work. Frosty
