FPD726 Copper Clad Stainless Steel Wire – Round, Flat & Y-Shaped Composite Metal Wire
Copper clad stainless steel wire (FPD726) replaces solid copper wire in round, flat and Y-shaped profiles at 40-50% of the cost – keeping the copper look, plating quality and non-magnetic performance, with a stronger stainless steel core.
- Three wire profiles – round, flat and Y-shaped, customized to your production.
- Cut copper cost roughly in half – same appearance and electroplating, far lower material cost.
- Non-magnetic, inspection-safe – passes 8-level needle detection for zipper and garment hardware.
- Stronger than solid copper – stainless steel core adds strength for stamping and forming.

FPD726 Copper Clad Stainless Steel Wire (Round, Flat & Y-Profile)
Precision Bimetallic Composite Wire — 40%–50% of Pure Copper Cost: Fullgreat Metal’s proprietary FPD726 copper clad stainless steel wire features a metallurgical tri-layer composite structure (Copper Outer Layer + Non-Magnetic Stainless Steel Core + Copper Outer Layer). Engineered to replace expensive solid copper and brass wire, it delivers identical surface appearance, electrical conductivity, and electroplating performance while adding the high tensile rigidity of an austenitic stainless steel core.
- Needle-Detection Compliance: 100% passes Japanese/European 8-level garment needle detection tests with zero false alarms on retail EAS security gates.
- Multi-Profile Supply: Available in continuous round wire, cold-rolled flat wire, and precision Y-shaped zipper profiles.
- Downstream & Upstream Linkage: Explore our stamped Y-Teeth Zipper Wire and sister product Copper Clad Stainless Steel Strip (FPD726).
Available Wire Profile Types
1. Round Composite Copper Wire
Designed for precision electronic pins, terminal connectors, spring hardware, and craft wire requiring high electrical surface conductivity and stainless anti-sagging tensile strength.
2. Flat Composite Copper Wire
Cold-rolled with smooth, rounded, or deburred edges. Ideal for continuous electrical contact springs, cable shielding bands, and decorative metal border inlays.
3. Y-Shaped Composite Zipper Wire
Precision preformed for automated zipper teeth stamping lines. Combines a warm brass look with high lateral chain strength and certified non-magnetic needle-safe compliance.

FPD726 Composite Wire vs. Solid Copper Wire
| Performance Factor | FPD726 Copper Clad SS Wire | Solid Pure Copper / Brass Wire |
|---|---|---|
| Material Cost | 40% – 50% of Pure Copper | 100% (High & Volatile) |
| Appearance & Texture | Genuine copper/brass finish for luxury goods | Reference copper finish |
| Electroplating Adhesion | Flawless (Plates onto genuine copper) | Reference standard |
| Magnetic Behavior | Strictly Non-Magnetic (Passes 8-level needle test) | Non-Magnetic |
| Tensile & Fatigue Strength | High (Stainless steel core prevents stretching/breakage) | Soft (Stretches easily, lower yield strength) |
| Price Stability | Reduced copper content mitigates market volatility | Directly exposed to LME copper market surges |
