Overview
Ta1 Tantalum Wire is a pure tantalum wire product supplied in small diameter form. It is usually selected when buyers need tantalum material for winding, tying, fixing, small lead-type parts, furnace-related wire use, straight wire sections or custom tantalum wire components.
This product is different from Ta1 Tantalum Rod. Rod is a larger solid round form and is usually checked by diameter, cut length, end face and machining route. Tantalum wire is checked more by wire diameter, coil form, straightness, flexibility, surface cleanliness, temper condition and whether the wire will be wound, tied, cut or fitted into a small assembly.
For Ta1 tantalum wire orders, diameter and supply form are very important. A small change in wire diameter may affect flexibility, weight, handling method and packing. If the wire will be used in vacuum furnace fixtures, winding parts, tie wire, small lead pieces or special formed shapes, the actual application should be confirmed before quotation.

Product Description

Small-Diameter Tantalum Wire
Ta1 Tantalum Wire is supplied as small-diameter pure tantalum material. It is selected when the buyer needs wire form instead of rod, sheet, plate or tube. Diameter, tolerance and wire form should be confirmed before quotation.
Coil and Straight Wire Use
Depending on the order, tantalum wire can be checked in coil form, spool form, straightened length or short cut sections. Coil wire is easier for continuous use, while straightened wire is more practical for fixed-length assembly or small formed parts.
Winding and Fixing Applications
Tantalum wire may be used for winding, tying, fixing, lead-type pieces or selected vacuum/high-temperature assembly use. The actual temperature, atmosphere, contact medium and assembly method should be reviewed before material selection.

Clear diameter, supply form and use method help us check whether the order should be supplied as coil wire, straight wire or custom cut tantalum wire sections.
Material Fit
Winding Wire Use
Ta1 tantalum wire may be considered when the final part needs a small-diameter wire for winding or forming. Diameter, flexibility and temper condition should be checked.
Tying and Fixing Use
Wire form is practical for selected tying, fixing or binding work in suitable assemblies. Wire strength, bending behavior and working atmosphere should be reviewed.
Lead-Type Wire Parts
Tantalum wire can be checked for small lead-type parts or short wire sections where diameter, surface cleanliness and cut length are important.
◆ General Note: Tantalum grade selection should be checked with actual service condition, temperature, atmosphere, medium, wire diameter and buyer specification.
Processing & Supply

Wire Diameter Checking
Ta1 Tantalum Wire can be checked by diameter, tolerance, quantity and supply form. Fine wire and thicker wire may follow different handling and packing routes.
Coil or Straight Supply
Wire can be reviewed as coil, spool, straightened length or fixed cut pieces. The suitable form depends on buyer use, diameter, quantity and packing requirement.
Cut and Formed Wire Pieces
Short wire sections or simple formed wire pieces can be discussed by drawing or sample. Cut length, end condition and deformation requirement should be confirmed.

Applications
Tantalum Tie Wire
Used as tantalum wire for selected tying or fixing work where diameter and bending behavior should be confirmed.
Winding Wire
Used for winding-type tantalum wire parts where coil form, temper and wire diameter matter.
Vacuum Furnace Wire Use
Used for selected vacuum furnace-related wire applications where atmosphere, temperature and surface condition should be reviewed.
Lead-Type Wire Sections
Used as short tantalum wire sections or lead-type pieces where diameter and cut length are important.
Straightened Tantalum Wire
Used when buyers need straight tantalum wire lengths instead of coil or spool supply.
Custom Wire Components
Used for non-standard tantalum wire parts with special diameter, length, shape, surface or packing requirement.
Packing & Delivery
Coil Protection
Coiled tantalum wire should be packed to reduce tangling, local bending and surface marks during shipment.
Spool Handling
Spool packing can be checked when continuous wire handling is required. Spool size and wire weight should match the order details.
Straight Wire Packing
Straightened wire or cut wire sections can be packed with support according to diameter, length and surface condition.

FAQ
Q1: What is Ta1 Tantalum Wire used for?
A: Ta1 Tantalum Wire is used for tie wire, winding wire, fixing wire, lead-type wire sections, straightened wire lengths and selected vacuum or high-temperature assembly use.
Q2: How is tantalum wire different from tantalum rod?
A: Tantalum wire has a smaller diameter and is usually supplied in coil, spool, straightened or cut length form. Tantalum rod is larger solid round material and is usually checked by rod diameter, length and end condition.
Q3: What information is needed for quotation?
A: Please send grade, wire diameter, quantity, supply form, surface condition, temper condition and application. A drawing is recommended for formed wire parts.
Q4: Can Ta1 tantalum wire be supplied in coils?
A: Yes, coil supply can be checked according to wire diameter, quantity and packing requirement. Spool packing can also be reviewed if needed.
Q5: Can tantalum wire be supplied as straight lengths?
A: Straightened wire or fixed cut sections can be checked. Please provide diameter, length, quantity and length tolerance if important.
Q6: What surface finish can be discussed?
A: As-processed, cleaned, bright or polished surfaces can be discussed. The suitable surface depends on the working environment and buyer requirement.
Q7: Is Ta1 the same as R05200?
A: Ta1 and R05200 are different grade naming systems. If a drawing or standard specifies R05200, it should be confirmed before replacing it with Ta1.
Q8: What affects delivery time?
A: Delivery time depends on grade, wire diameter, quantity, supply form, surface condition, temper requirement, straightening, cutting and any drawing-based wire preparation.
