Tantalum plate is one of the most common metal materials.

A kind of filamentous tantalum material is made from tantalum powder by rolling, drawing and other plastic processing methods.

Almost all tantalum plates are cold worked.

Tantalum cannot be processed in the usual way that ordinary metals are processed. Generally, the initial process is forging and heat treatment, using hammering and stamping two ways to make plate blank or round small and medium-sized blank.

Niobium can be produced by electrolytic melting of potassium heptafluoroniobate.

Smelting method: tantalum and niobium ore is often accompanied by a variety of metals.
