Tantalum Sheet

Category:

Tantalum sheets are rolled from thicker tantalum plates and can be rolled into thinner strips & foil.

Edgetech Industries LLC provides high purity tantalum sheet (Ta sheets) to universities, research labs and manufacturing companies. Tantalum sheets can be deformed very well, whether for punching, cutting, deep drawing or pressing.

Tantalum and tantalum alloy products are also available in form of foil, wire, rod, ribbon, pellets, powder, sputtering targets, discs, etc. We are able to fabricate the above tantalum products to your specification and drawings.

We provide tantalum sheet with following dimensions and specifications

Tantalum metal is part of the refractory metals group, which are widely used as minor components in alloys. Tantalum is a chemical element with the symbol Ta and atomic number 73.

Tantalum Square

Ta is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. Also, it is highly ductile at high temperatures. They have excellent thermal and electrical conductor properties.  The melting point of 2,996°C of Ta, is the fourth highest of all metals.

The chemical inertness of tantalum makes it a valuable substance for laboratory equipment and a substitute for platinum. Its main use today is in tantalum capacitors and in electronic equipment. Such as mobile phones, DVD players, video game systems, and computers.

Packing information for our Tantalum Sheet

Our products are mostly packed in wooden crates, this can protect the tantalum sheet during transportation and handling. Carton is used for small pieces of tantalum sheet.

We can also provide custom tantalum products, please send us your request to sales@edgetechmat.com for any needs on tantalum rolling products.
