Tungsten (W) Wire, 99.95% Purity (Request Current Price)

ZHC LAB Tungsten (W) wire is a high-purity 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 precise cutting, weighing, fixture loading, and small-batch experimental work where material identity, purity, and clean handling are important. Pricing requires a current quote because high-purity wire and rod costs vary with purity, diameter, package size, and material market conditions.
