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



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.
