Which format
Same two alloys — the difference is how much machining ships with them
Grade selection is one decision. Format is the other, and it is the one that moves price and lead time. Here is what actually changes between the five.
| Format | Grades | What ships | Lead time | Pick it when |
|---|---|---|---|---|
| Electrode wheels | 75/25 · 70/30 | Finish-machined to your drawing — bore H7, 0.02 mm runout, flat or bevel or R or knurled face | 10–14 days · 20–25 custom | The part is the seam-welding consumable and mounts on a shaft |
| Rods & blocks | 75/25 · 70/30 | Rough-machined or ground stock — round rod, rectangular block, near-net blank | 10–14 days | You machine your own caps, shanks or EDM electrode sections |
| Threaded electrodes | 75/25 · 70/30 | Metric or UNC/UNF thread to drawing, shoulder geometry to suit your gun or holder | 10–14 days · 20–25 custom | The electrode screws into something rather than being clamped |
| Custom parts | 75/25 · 70/30 | Any geometry inside OD 400 × 100 mm, quoted per drawing | 20–25 days (tooling + machining) | It is not a wheel, a rod or a threaded stud — a fixture, facing or contact assembly |
Every format is W/Cu 75/25 or 70/30 — below the 80% tungsten line, so parts ship as ordinary industrial goods with no export-licence step. Grades above that line are not in our export range and we decline them at quotation rather than after your tooling is committed.
1 · Does it screw on?
Then the thread callout and shoulder geometry decide whether it seats. Read how to specify threaded electrodes.
2 · Do you machine it?
Then buy stock and skip the second setup — how to buy rods and blocks covers sizes and delivery condition.
3 · Neither?
Most buyers are here, and it is the cheaper route on anything with a bore, a profile or a tolerance. Ordering custom wheels walks the drawing through.
Whichever format you land on, the grade decision underneath is the same two options — W75Cu25 against W70Cu30 is the comparison that decides it, and it comes down to wear life traded against conductivity.
