More info

Tantalum sheets contain pure tantalum sheets and tantalum-tungsten alloy sheets. Our tantalum sheets have bright surfaces, no cracks, no peeling, no folding, and no obvious defects such as oxidation and impurities pressed in. Tantalum sheets usually deform well even at temperatures well below room temperature, whether punched, cut, drawn, or pressed. Tantalum sheets can be machined effortlessly to meet your specific needs.

Tantalum and Tantalum Alloy Sheet Application

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.
