Tantalum sheets are made from tantalum plates through a rolling process. They have the special properties of all tantalum materials and are used in various fields.

Edgetech Industries (ETI) is a leading global supplier of tantalum flakes, including medical grade tantalum flakes. We offer tantalum plates in various sizes with short delivery times. We have been supplying the highest quality Tantalum Plate for over a decade. Edgetech provides conflict-free materials in the Democratic Republic of Congo.

Tantalum sheet production process

Tantalum sheets are almost entirely made using cold processing technology. Generally, 15-30cm tantalum ingots are cold forged into 8-10m thick slabs, and then the slabs are cold-rolled with a compression rate of over 95%. In commercial production, slabs are usually rolled by two or four rolling mills into 0.63-1.2cm thick plates, with widths generally ranging from 51 to 102cm. Rolling is typically performed at or near room temperature to prevent surface oxides from forming. When hot rolling is required, the temperature will rise to 1000°C due to recrystallization, and a violent oxidation reaction will occur.

Almost all thick tantalum sheets are annealed by vacuum heat treatment. Since there are no phase changes, the rates of heating and cooling are not important. It is further rolled using a conventional rolling mill, usually a four-high multi-roll mill.
