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 diffusion barrier in x-ray machines.
