Flat Wire Supplier & Manufacturer
Fullgreat Metal is a precision flat wire manufacturer producing custom flat wire by cold rolling and slitting drawn wire — in stainless steel, aluminum, copper, iron and composite copper. As a factory-direct flat wire supplier, we control rolling, slitting and edge conditioning in-house, holding cross-section tolerance to ±0.01 mm with surface finish, temper, edge condition and packaging matched to your production line.
Flat wire is the material behind transformer windings, electronics connectors, zipper teeth, precision springs, wiper blades and decorative hardware. Send us the profile, grade and volume — our engineering team confirms feasibility, samples and quotes with full MTC documentation.

Materials & Grades
- Stainless steel flat wire — 304, 316L, 201, 430 and non-magnetic grades FPD901/FPD902, for zippers, medical devices, electronics and hardware. For the non-magnetic difference, see our non-magnetic stainless steel grades compared guide.
- Copper flat wire — C11000/T2 pure copper at 99.9% conductivity, produced to ASTM B152 / JIS H3100 for transformer windings, connectors and busbars.
- Aluminum flat wire — 5052, 5182, 6061, 6063 and 7050 alloys for automotive, electronics and lightweight structural applications.
- Iron / composite copper — cost-effective options for specialty electrical and mechanical applications.
Why Buy Flat Wire Direct from the Manufacturer
- Factory-direct control — in-house rolling, slitting and edge conditioning means consistent profile, straightness and surface quality coil after coil, not trading-house resale.
- ±0.01 mm tolerance — precision-rolled width and thickness that feed high-speed stamping and forming lines without drift.
- MTC traceability — every shipment carries a Mill Test Certificate with heat number, chemistry and mechanicals. See what a 3.1 certificate must contain in our MTC / EN 10204 3.1 explainer.
- Certified quality — ISO 9001:2015 and GRS certified, with more than 100 sets of processing and testing equipment.
- Proven scale — serving 1,000+ enterprises across 20+ countries since 2008, with 50,000 tons monthly capacity and 10,000 tons inventory.
