More info

The tantalum sheets come in pure tantalum and tantalum-tungsten alloy variations. They feature bright surfaces with no cracks, peeling, folding, oxidation, or impurities pressed in. Tantalum sheets exhibit excellent deformability even at temperatures below room temperature, allowing for easy punching, cutting, drawing, and pressing. These sheets can be machined effortlessly to meet your specific requirements.
