CAPABILITIES / TECHNICAL REFERENCE
Custom drawn wire, cable, and specialty alloy conductors — the spec book an engineer actually bookmarks.
47 stocked alloy families, diameter range 0.003″ to 0.500″ held to ±0.0005″, in-house metallurgists review every RFQ before quote, and a 14-day standard lead time on custom orders. The full ProEdge Wire capability catalog is below — same data the applications engineering team uses to scope your next run.

02 — FROM RFQ TO SPOOL
How a quote becomes a spool.
Every ProEdge Wire order passes through the same five-stage flow. Metallurgists review your RFQ before quote, not after — so the number you receive is the number you can plan production against.
-
01
RFQ intake & engineering review
Your RFQ lands with the applications engineering group (9 people, 41 years combined wire experience). An engineer and a metallurgist confirm alloy, temper, tolerance, and finish against the spec — and flag anything that won't draw, anneal, or plate cleanly.
-
02
Quote with documentation plan
You receive a line-item quote priced against your tolerance band and alloy. Every quote ships with the documentation plan pre-mapped — PPAP, IMDS, C of C, REACH/RoHS statements — so there's no renegotiation at PO.
-
03
Draw, anneal, plate, insulate
Production runs on redundant draw, anneal, and plating lines across the Cleveland and Twinsburg facilities. In-process laser micrometry at every die stand; SPC charts retained per lot for seven years.
-
04
Final inspection & documentation
Every spool leaves with a Certificate of Conformance, dimensional report, and (where required) full PPAP/IMDS packets. Exotic alloy runs receive an additional metallurgical cross-check before sign-off.
03 — STOCKED ALLOY LIBRARY
47 alloy families, four base-metal groups, one lookup.
Every alloy listed is on the floor at one of our two Midwest facilities — not on a vendor's stocking agreement. If your target alloy isn't in the matrix below, ask: we routinely add chemistries to the stock list against qualified-volume RFQs.

04 — DIAMETER & TOLERANCE
Published tolerance bands across the entire diameter range — not just on hero sizes.
ProEdge holds four working bands from 0.003″ to 0.500″. Each band carries a published standard tolerance; tighter tolerances are routinely achieved on qualified repeat orders — confirmed in your quote, not promised in marketing copy.
BAND 02
0.010″ – 0.032″
- Held tolerance
- ±0.0002″ standard, ±0.0001″ on qualified runs

- Typical use
- Medical lead wire, magnet wire feed stock, aerospace harness
BAND 03

±0.0005″
The tightest published tolerance on the largest stock size. Most wire houses only hold this on their hero SKUs. ProEdge Wire holds it across the full 0.003″ – 0.500″ range on qualified orders — confirmed on the quote, not promised on the homepage.
05 — PLATING & INSULATION
Secondary processing as a configurable menu — every option is in-house.
No sub-contracted plating houses. No “we'll send it out for enameling and re-receive it in three weeks.” Tin, silver, nickel, gold, and the full insulation stack all run on the ProEdge production floor under one quality system.
PLATING
Tin, silver, nickel & gold
Electroplated and hot-dip tin for solderability; silver for high-frequency conductivity; nickel for oxidation resistance at temperature; gold for biomedical and aerospace termination. Thicknesses from 10 µin to 200 µin, controlled per ASTM B545 / B700.
- Tin — electro & hot-dip
- Silver — 99.9% pure, bright or matte
- Nickel — sulfamate or Watts
- Gold — Type I & II, hard & soft
INSULATION
Enamel & polymer film
Builds from single-film through quadruple-film, NEMA MW 35-C / MW 73-C compliant. Polyesterimide, polyester (THEIC-modified), polyamide-imide overcoat, and polyurethane for bondable / solderable applications without mechanical stripping.
- Polyurethane (solderable, 155–180°C)
- Polyesterimide (200°C thermal class)
- Polyamide-imide overcoat (220°C)
- Bondable / self-bonding overlays
HIGH-TEMP
PTFE, Kapton & served fiberglass
For applications where organic enamel is not enough — aerospace, defense electronics, downhole, and medical where sterilization temperature or outgassing specs rule out polymer films. Spiral served or braided, single or double layer.
- PTFE extrusion (260°C continuous)
- Kapton (polyimide) tape wrap
- Fiberglass served & silicone varnished
- Mica tape for >500°C exposure
ASSEMBLY
Stranding, bunching & cabling
From 7-strand concentric through 61-strand RFL lay, plus custom bunched and SZ-strand constructions. Cabling up to 7 insulated cores with controlled lay length, fillers, binders, and shields per your print.
- Concentric, unilay, RFL, SZ
- 7 through 61 strands standard
- Shielded: serve, braid, or foil
- Custom lay length per print
Prototype run · 50 lb minimum · same documentation packet as production runs
06 — LOW MOQ PROGRAM
Prototyping and R&D runs are a designed capability — not an exception.
Specialty wire houses are usually built for the 5,000 lb run and treat the 50 lb prototype as a nuisance. ProEdge runs the opposite model. The Low MOQ program is priced and scheduled separately so a small batch doesn't queue behind a Tier 1 automotive blanket order.
- 50 lb
- Minimum order. Custom wire runs starting at 50 lbs for prototyping, R&D, and design-validation work. Below 50 lbs we'll quote case-by-case for qualified projects.
- 14d / 5d
- Lead time. 14-day standard, with a documented rush capability down to 5 business days for qualified customers. Both numbers measured against the published logistics dashboard — not aspirational.
- 100%
- Documentation parity. A 50 lb prototype run receives the same Certificate of Conformance, dimensional report, and (where applicable) PPAP packet as a 50,000 lb production run. No “sample paperwork.”
