Tantalum Sheet / Plate
Tantalum Sheet / Plate production process
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%. In commercial production, the slabs are usually rolled into 0.63-1.2cm thick plate by two or four rolling mills, width is generally 51~102cm. Typical rolling is done at or near room temperature to prevent oxides from forming on the surface. In need of hot rolling, because of recrystallization, the temperature will rise to 1000 ℃ and the violent oxidation reaction will happen.
Almost all thick Tantalum Plates are annealed by heat treatment in vacuum. Since there is no phase change, the rate of heating and cooling is not important. Further rolling with a common mill, usually use of a 4 - roll mill multi - roll mill. Because the Tantalum metal is very soft, caution should be taken to prevent scratches during processing and transportation.
