More info

HM provides high-quality Tantalum Strip/Foil at a competitive price, which can be used in Scientific research or industrial production.

Tantalum (Ta) Metal Strip/Foil

Tantalum strip/foils are often deformed very well even far below room temperature. Whether for punching, cutting, deep drawing, or pressing: you'll be able to machine our tantalum strip/foils without difficulty to meet your specific needs. Tantalum is significantly corrosion resistant. Acids and bases cannot damage our strip/foils. Strip/Foils fabricated from tantalum are used for instance within the chemical industry for water purification or as a diffusion barrier in x-ray machines.

Heeger Materials(HM) supplies tantalum strip/foils in a length of up to 3.2 meters and in a width of up to 800 millimeters. Just contact us!
