99.95% Pure Tantalum Wire for Stable Performance
Pure tantalum wire is valued for its excellent corrosion resistance, high melting point, good ductility and stable performance in demanding environments.
Compared with common metals, tantalum performs better in many corrosive, high-temperature and special chemical conditions. This makes it suitable for applications where material purity, corrosion resistance and long-term stability are important.
Ehisen can supply tantalum wire for both standard material demand and custom processing projects.
Pure tantalum wire can be classified according to its chemical purity, performance, use and status：
It is divided into 3 categories according to chemical purity: (1) Metallurgical tantalum wire, purity 99.0% Ta; (2) High-purity tantalum wire, purity 99.0% ~ 99.9% Ta; (3) Ultra-high purity tantalum wire, purity 99.9% ~ 99.99 %Ta.
According to performance, it is divided into 4 categories: (1) Chemical corrosion-resistant tantalum wire; (2) High-temperature-resistant and high-strength tantalum wire; (3) Oxygen-resistant and brittle tantalum wire; (4) Capacitor tantalum wire.
Capacitor tantalum wires are divided into 3 categories according to their uses: (1) Tantalum wires for solid tantalum electrolytic capacitors (SDTa1, SDTa2) (GB/T 26012-2010); (2) Tantalum wires for liquid tantalum electrolytic capacitor leads (LDTa1, LDTa2) (GB/T 26012-2010); (3) Tantalum wire (DTals, DTalL) for capacitors with reliability indicators (GJB2511-95).
Capacitor tantalum wire is divided into three categories according to its state: (1) Soft state (M), tensile strength σb = 300 ~ 600MPa; (2) Semi-hard state (Y2), tensile strength σb = 600 ~ 1000MPa; (3) Hard state (Y), tensile strength σb>1000MPa.

Tantalum Wire Applications
Capacitor Lead Wire
Pure tantalum wire is commonly used as lead wire for tantalum capacitors. For this application, material purity, diameter consistency and surface condition are important.
If your project is related to capacitor production, please send us your required diameter, tolerance, spool form and certificate requirement.
Vacuum Furnace Components
Tantalum wire can be used in vacuum furnace parts, high-temperature support structures, heating-related components and special furnace fixtures.
For vacuum furnace applications, please confirm the working temperature, atmosphere, wire diameter and required mechanical condition before quotation.
Chemical and Corrosion-Resistant Equipment
Tantalum has strong corrosion resistance in many chemical environments. Tantalum wire can be used for chemical equipment parts, corrosion-resistant support structures and special process components.
Please send your working medium, concentration, temperature and application details so we can better understand your requirement.
Evaporation, Sputtering and Laboratory Use
Tantalum wire can also be supplied for evaporation materials, sputtering-related use, laboratory testing, research projects and small custom metal parts.
Small quantity orders can be discussed depending on diameter, stock and processing requirement.
How to Choose the Right Tantalum Wire
Choosing tantalum wire is not only about purity. The right specification depends on your actual working condition and downstream process.
Please consider the following points before ordering:
| Selection Factor | Why It Matters |
|---|---|
| Diameter | Affects strength, flexibility, conductivity and processing method |
| Purity | Important for capacitor, laboratory and high-purity applications |
| Condition | Annealed wire is softer; hard wire provides higher mechanical strength |
| Surface | Surface cleanliness affects welding, assembly and chemical performance |
| Supply Form | Coil, spool or straight wire should match your production process |
| Application | Different applications may require different grades and certificates |
| Quantity | Stock size and custom size may have different MOQ and lead time |
If you are not sure which tantalum wire to choose, send us your application details. We can help review your requirement before quotation.
Custom Tantalum Wire Processing Support
For some projects, buyers may need more than standard wire supply.
Ehisen can discuss custom processing based on your drawings or samples, such as:
● Cut-to-length tantalum wire
● Straightened tantalum wire
● Custom diameter tantalum wire
● Special surface treatment
● Small tantalum wire parts
● Tantalum wire for assembly or testing
If your part has strict tolerance or special assembly requirements, please send us the drawing first. Our team will review the production feasibility before quotation.
