Tantalum is part of the refractory metals group with high melting points and good mechanical properties. Tantalum foil/Strip has the perfect resistance to the corrosion. TRM can provide tantalum foil/Strip with uniform thickness. Standard Specification for the tantalum sheet/plate is ASTM B708 and ASTM F560 for Medical Applications.Higher purity 99.95% or even 99.99% is available on request. Our tantalum material is from Non-Conflict Resource.
Application: Tantalum foil/strip is widely used in semiconductor and electronics, defense, furnace parts, chemical processing and medical industry.
