Tantalum (Ta) Disc | ALB-T005

Item No.: ALB-T005. Tantalum (Ta) Disc is made of pure tantalum with purity over 99.95%. Size available: Diameter: 15-400mm; Thickness: 3-28mm. Standard: ASTM B 708.

Tantalum (Ta) Disc Description:
Tantalum (Ta) Disc are made from tantalum plate. Because tantalum has the ability to form thin oxides, and the resulting oxide film has a protective effect, tantalum is widely used as a base material for electrolyte capacitor manufacturing.
ALB Materials Inc is a global supplier of Tantalum (Ta) Disc and we can provide customized tantalum products. ALB's Tantalum (Ta) Disc is manufactured through Cold-Working Process, through forging, rolling, swaging, and drawing to get the desired size.

 

Tantalum (Ta) Disc Applications:

  • Used in thermal inkjet printhead, can form anti cavitation film.
  • Used in integrated circuit with the base coating process to form a tantalum film which can prevent the diffusion of copper into the substrate silicon.
  • Used in liquid crystal display (LCD), as well as heat, corrosion resistance, high conductivity and other coating industries.
