Aerospace & Defense Wire Catalog
Every MS20995 / NASM20995 and MS9226 safety wire item American Wire Works stocks, cross-referenced by part number, alloy, diameter, and service condition — plus the supporting lines that go with them on engine, airframe, and shipboard work. Stocked in Folcroft, Pennsylvania. Quote the part number off the drawing and we respond the same business day.

Alloy ranges and governing standards
The full diameter range carried for each alloy, with the material standard behind the MS/NASM designation. Use this when the drawing calls a diameter that is not a stocked catalog item.

Choosing by service condition
Turbine hot section, exhaust, breeching
Inconel (MS20995N) or Inconel 600 to AMS 5687 (MS9226). Stainless anneals and loses clamping force at these temperatures.
Naval, shipboard, coastal ground equipment
Monel 400 (MS20995NC). Chlorides pit and stress-corrosion-crack stainless over time; Monel is the standard answer.
General airframe, landing gear, nacelle, line MRO
Stainless steel (MS20995C). The default across most of the fleet — 0.032" is the most common diameter.
Anti-galling and predictable breakaway
Cadmium-plated copper (MS20995CY) where the joint has to release at a known load rather than hold indefinitely.
Supporting lines
What ships alongside safety wire on engine, test cell, and shipboard programs.
Inconel Tie Wire
Soft annealed Inconel for removable insulation blankets, exhaust lagging, and breeching on engine test cells and generator sets — the same 1,600°F service class as Inconel lockwire, in tie-wire gauges.
View Inconel Tie Wire→Monel Tie Wire
Nickel-copper tie wire for shipboard and coastal installations where chlorides would pit stainless. Standard on naval insulation and marine mechanical work.
View Monel Tie Wire→Knitted Stainless Mesh
304 knitted mesh, .0095" wire, 900°F continuous / 1,200°F peak, in 24"–42" widths for removable blanket fabrication and lagging support on exhaust and turbine hardware.
View Knitted Stainless Mesh→Stainless Spring Wire
Stainless spring wire for retention clips, detents, and formed components. Specify temper, diameter, and finish on the RFQ.
