99.95% High Quality Tantalum Foil & Strip
Product Description
Tantalum foil has excellent corrosion resistance, high temperature stability, biocompatibility, good processability, and other characteristics, and is widely used in cutting-edge technology fields such as electronics, chemicals, medical treatment, and aerospace.
Tantalum foil can generally be produced and processed through powder metallurgy and rolling processes. We use advanced forging technology to refine the internal grains of tantalum ingots, and the,n through repeated precision rolling and annealing, the foil reaches the finished thickness. The finished tantalum foil has high purity (Ta≧99.95%), precise size, bright surface, no cracks, no peeling, good flatness, and meets ASTM B708 standards.
We also offer tantalum rods, tubes, sheets, wire, and tantalum custom parts. If you have product needs, please email us at info@winnersmetals.com or call us at +86 156 1977 8518 (WhatsApp).
