Ordering tantalum wire starts with the intended process, the required form, and a drawing or clear dimensional schedule. Specify grade, diameter, length, condition, quantity, and the inspection documents your project needs. A supplier can then check the request against an available product and confirm what can be supplied.
Start with the application and material grade
State whether the wire is intended for capacitor production, a vacuum component, laboratory work, or another use. These applications can require different grades and handling. The MetalsTek tantalum wire product page lists several tantalum and tantalum-alloy grades; identify the grade on your drawing or ask the team to review your process conditions. If you need material documentation, specify the exact certificate or test report required for your order rather than assuming that every listed grade carries the same documents.
Define diameter, length, and condition
Give the nominal diameter and acceptable tolerance, length per piece or spool, and total quantity. If winding, forming, or tensile behavior matters, state the required condition and any measurable acceptance criterion. The product page includes size and property information, but the exact combination should be confirmed against your drawing and order quantity. Tell the supplier whether scratches, kinks, surface residue, or special handling would affect your process.
Check the drawing and inspection package
A useful RFQ includes the application, grade, diameter and tolerance, length, condition, surface requirement, quantity, destination, and requested delivery date. Attach a drawing when end preparation, straightness, spool geometry, or packaging matters. Ask which dimensions will be inspected and what records will accompany the shipment. MetalsTek also provides a sample tantalum wire COA on the product page; confirm the documentation required for your own batch.
Related tantalum forms
If your design calls for a flat form rather than wire, compare the tantalum sheet, foil and ribbon product page and the sheet, foil and plate buyer guide. The selection should follow the part geometry and manufacturing process, not a generic material claim.
Frequently asked questions
What information should I send for a tantalum wire quote?
Send the grade, diameter and tolerance, length or spool requirement, condition, quantity, destination, and any drawing or inspection requirement. Include the intended use if it affects material selection.
Can I use the listed size range as a guaranteed stock list?
No. The product page describes available offerings; confirm the exact grade, diameter, condition, quantity, and delivery schedule in the quotation.
Does every tantalum wire order include the same certificate?
Documentation depends on the requested grade and order. State the certificate or test data needed in the RFQ and confirm its availability before purchase.
