Tantalum Sheet is almost all made using cold processing technique. Generally, Tantalum Ingots of 15 ~ 30cm will be cold forged into slab of 8~10m thickness, and then be cold rolled from such slab, the compression rate can be more than 95%.

Further rolling with a common mill, usually use of a 4 - roll mill multi - roll mill. Because theTantalum metal is very soft, caution should be taken to prevent scratches during processing and transportation.
