Product Overview
Tantalum wire is manufactured from high-purity tantalum powder through rolling and drawing processes, producing fine wire materials widely used in electronics, capacitors, vacuum electronic devices, and high-temperature structural components. Key characteristics include corrosion resistance, high-temperature tolerance, excellent electrical conductivity, and mechanical strength.

Selection & Usage Guidelines
Application Determination: Capacitor applications require half-hard or hard condition wire per GB/T 3463-1995/ASTM B365; medical or high-temperature structural applications require ASTM F560 or high-temperature high-strength grades
Purity & Alloy Composition: For high-reliability electronic components, recommend 99.95%-99.99% ultra-high purity tantalum wire; for special corrosion resistance or strength requirements, select Ta-W or Ta-Nb alloys
Dimensional Tolerances & Bending Cycles: Reference bending cycle tables when designing bending paths to avoid oxidation-induced fracture from exceeding specified cycles
Packaging & Moisture Protection: Tantalum wire is moisture-sensitive; recommend moisture-proof packaging and dry environment storage to prevent surface oxidation affecting electrical performance
