Tantalum Strip and Foil

Admat supplies coiled tantalum strip and foil in a wide range of thicknesses and widths. Our strip and foil are precision rolled, annealed and shipped on sturdy cores. Our products are typically produced to meet typical ASTM, AMS or specific deep draw specifications, we also welcomes customer developed specifications. If you are just engineering your product requirements, our engineers will help you design a specification suited to your application.

Admat offers both powder metallurgy derived and electron beam processed tantalum strip and foil. The powder metallurgy grade tantalum is perfect for deep drawing and stamping applications. It ensures drawn parts have a smooth surface, free of cracks and pits. The isotropic properties of the strip help to avoid erratic can height or “earring”problems. When ordering this material, specify “Powder Met Grade” or order to ASTM B708 R05400.

For high temperature applications such as furnace hardware, Admat has grain stabilized tantalum strip and foil. This product is engineered to significantly increase the product life by slowing grain growth at high temperatures.

No matter what your application, let our tantalum experts work with you to develop the proper material requirements for your application.
