A guitar string is primarily made by Wire / Rod / Tube Drawing. Drawing pulls metal through a die to reduce its diameter and increase length, used to make wire, rod and tube. Below is the full route to make a guitar string, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.

Step by step

How a guitar string is made

The usual route, raw material to finished part. The amber step is where the guitar string gets its basic shape.

  1. Feedstock

    Start from cast billet, bloom or slab.
  2. Wire / Rod / Tube Drawing

    Form the guitar string as a continuous drawn length and cut it to length.
    Tooling Low to medium   Tolerance ±0.01 to 0.1mm   Lead n/a (stock)
  3. Cut to size

    Saw or shear the stock to the lengths you need.
  4. Secondary work

    Machine, drill or bend wherever the raw section is not yet final.
    Tooling None   Tolerance ±0.125mm, to ±0.025mm   Lead 1 to 10 days
  5. Finish

    Deburr and, for aluminium, anodise; otherwise plate or coat.
    Tooling Low   Tolerance adds microns   Lead days
  6. Inspection

    Verify section, straightness and length.

Design tips

General pointers. The full design-for-manufacturing list for a guitar string is in the dossier.

  • Tolerance tighter than needed. Match standard tube/wire class.
  • No anneal called where forming follows. Specify temper.
Cost

What a guitar string should cost

Precise wire, rod and tube made by pulling through dies; bought by weight/length, tolerance improves per pass.
