Tantalum (Ta) Wire, 99.95% Purity (Request Current Price)

Tantalum (Ta) wire is a thin-film and materials-research source format supplied for PVD source loading, evaporation-related workflows, filament or wire studies, alloy preparation, and laboratory materials development. The wire and rod formats support cutting and weighing, fixture loading, and small-batch experimental work where material identity, purity, and clean handling are specified. Pricing requires a current quote because wire and rod costs vary with purity, diameter, package size, and material market conditions.

Features

Source Material
Available purity options include 99.95% (3N5) for research workflows that require controlled source composition.
