More info

Tantalum sheets 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 sheets without difficulty to meet your specific needs. Tantalum is significantly corrosion-resistant. Acids and bases cannot damage our sheets. Sheets fabricated from tantalum are used for instance within the chemical industry for water purification or as a diffusion barrier in x-ray machines.
