FPD726 Copper Clad Stainless Steel Strip & Coil – Non-Magnetic Bimetallic Composite Metal
Copper clad stainless steel strip (FPD726) is a patented three-layer composite – copper + non-magnetic stainless steel + copper – that replaces solid copper strip at 40-50% of the cost, without giving up the copper look, plating quality or non-magnetic performance.
- Cut material cost roughly in half – same copper appearance and electroplating, far lower cost than solid copper.
- Non-magnetic, inspection-safe – stainless steel core passes 8-level needle detection, ideal for garments, zippers and hardware.
- Copper look, stainless strength – high-end appearance with better mechanical strength than pure copper.
- Fully customizable – widths, thicknesses and tempers tailored to your stamping or forming process.

FPD726 Copper Clad Stainless Steel Strip & Coil
Engineered as a Cost-Effective Solid Copper Replacement: Copper clad stainless steel strip & coil (FPD726) is a tri-layer metallurgical composite (Copper + Non-Magnetic Stainless Steel + Copper) engineered by Fullgreat Metal. It delivers the genuine appearance, electrical conductivity, and electroplating performance of pure copper at approximately 40%–50% of the material cost, while the austenitic stainless steel core adds mechanical rigidity and verified non-magnetic performance that pure copper cannot guarantee.
If you currently purchase solid copper or brass strip for zipper components, buttons, furniture hardware, kitchenware trims, or electronic connectors, FPD726 lets you maintain premium copper aesthetics while cutting raw material expenditure roughly in half.
- Needle-Detection Compliance: 100% passes Japanese/European 8-level garment needle detection tests with zero false alarms on retail EAS security gates.
- Upstream & Downstream Pairing: Sourced alongside our Non-Magnetic Stainless Steel Strips and engineered for stamping into Y-Teeth Zipper Profiles.
- Full Material Comparison: Read our detailed guide on Copper Clad Stainless Steel vs. Pure Copper (FPD726).
What Is Copper Clad Stainless Steel Strip?
Copper clad stainless steel strip is a metallurgically bonded composite: pure copper or brass on the upper and lower surfaces, with non-magnetic austenitic stainless steel in the middle. Through specially designed production equipment and rolling techniques, the three layers are permanently joined to form a single strip that can be slit, stamped, deep drawn, and plated exactly like solid copper:
- Middle Core Layer: Non-magnetic stainless steel (FPD806 / SUS304 core), providing high tensile strength and absolute non-magnetic performance (μr < 1.01).
- Upper & Lower Outer Layers: Genuine copper or brass, delivering genuine metallic luster, high electrical conductivity, and flawless electroplating.
- The Result: The structural strength of stainless steel combined with the look, conductivity, and plating of copper—at half the cost.

FPD726 Copper Clad Strip vs. Pure Copper Strip
| Property | FPD726 (Copper Clad SS Strip) | Solid Pure Copper Strip |
|---|---|---|
| Material Cost | 40% – 50% of Pure Copper | 100% (High & Volatile) |
| Appearance | Genuine copper/brass finish for high-end goods | Reference copper finish |
| Electroplating | Identical to pure copper | Reference standard |
| Magnetic Property | Non-magnetic (100% passes 8-level needle test) | Non-magnetic |
| Mechanical Strength | Stainless steel core = Higher tensile & yield strength | Soft; bends and deforms under load |
| Conductivity | Comparable to copper for connectors & terminals | Highest baseline |
| Price Stability | Reduced copper content = Less exposure to LME price surges | Directly tied to volatile LME copper price |
💰 Significant Raw Material Cost Reduction
Because FPD726 utilizes non-magnetic stainless steel for its structural core, total copper consumption is cut by roughly half. Material cost drops to approximately 40%–50% of pure copper—a direct saving of 50%–60% on your raw material expenditure. For automated production lines consuming tons of copper monthly, this translates into substantial annual savings, especially during copper market rallies.
Typical Applications
| Application Field | Why Engineers Choose FPD726 |
