Tantalum: Properties & uses

Tantalum has high corrosion resistance and very easy to work at room temperature despite its body-centered cubic crystal structure. This makes it a valuable metal for a wide range of industrial applications. We use our extremely resistant material to make various products, including components furnace , pipeline for CPI and semi-finished products.
