Features

Tantalum ZD Material

ZD is ULVAC’s original material, developed for high-temperature manufacturing. When regular tantalum is used for extended periods at high temperatures, distortions occur as the tantalum grains grow, resulting in a shortening of product lifespan. ULVAC has led the industry in developing ZD, whose distortion at a high temperatures is controlled by adding a small amount of a special element. ULVAC has been manufacturing and supplying ZD for many years, and is constantly modifying and improving on this cutting-edge material.
