Product Specification
This copper-nickel composite strip is built for solar and renewable energy connections — copper core for low electrical resistance, nickel cladding for weldability and corrosion protection, custom per drawing. No grade designation applies; the construction is the specification. Produced on our own nickel-alloy line, every coil is inspected per batch before packaging.
| Parameter | Value | Note |
|---|---|---|
| Construction | Copper core, nickel cladding | single or double-side, per drawing |
| Clad ratio | Per drawing | confirmed at order |
| Thickness | Per drawing | core + cladding layers |
| Width / length | Per drawing | strip form, per order |
| Tolerances | Per drawing | locked at order confirmation |
MOQ and exact tolerances are confirmed per drawing.
Solar systems move real current from strings to inverters for decades. In a connection, resistance is heat: the lower the tab and joint resistance, the smaller the loss and the more stable the connection over its service life. The copper core delivers that low resistance, while the nickel cladding keeps the weld surface stable in outdoor service.
| Layer | Role |
|---|---|
| Copper core | Low electrical resistance, current carrying |
| Nickel cladding | Corrosion resistance, weldable surface |
| Clad ratio | Confirmed per drawing |
Produced on our own nickel-alloy line, every coil of composite strip passes dimensional, layer and surface inspection in our in-house inspection process before packaging. Construction is checked against the drawing per batch, so the strip you qualify on the sample matches the strip in the production run.
| Item | Scope |
|---|---|
| Per-batch inspection | Dimensions, layers, surface against the drawing |
| ISO9001 | Quality management system, plant-wide |
| EN 10204 3.1 MTC | Available with shipment on request |
| Traceability | Batch records for every delivery |
Typical use: solar bus connections, inverter terminals, renewable energy components and current-carrying joints. Grade-free construction per drawing gives design freedom across these duties.
This composite carries no grade designation and is quoted per drawing, based on construction (single or double-side cladding), clad ratio, dimensions and quantity. No indicative price range is published for this product — request a quotation with your drawing for a firm price.
| Core material | Copper |
| Cladding material | Nickel |
| Cladding | Single or double-side, per drawing |
| Clad ratio | Per drawing |
| Composition record | Per-batch inspection per drawing |
Physical properties (density, electrical conductivity, tensile strength) depend on the core/clad ratio and layer thickness. Values are confirmed per drawing — no catalogue values are claimed for this composite.
| Form | Composite strip (Cu core, Ni cladding) |
| Grade | None (construction per drawing) |
| Application | Solar and renewable energy connections |
| Size | Per drawing |
| Surface | Clean, oxide-free per drawing |
| Lead time | 7-15 days |
| Packaging | Export packaging per order |
| Dimensional tolerances | Per drawing |
| Nickel cladding family (where applicable) | ASTM B162 (Ni200/Ni201 strip); GB/T 2072-2020 (N4/N6 strip) |
| Composite verification | Per drawing, per-batch inspection |
Strip is packaged for export with edge and surface protection. Lead time: 7-15 days. Shipping documents and inspection records accompany every shipment.
Solar inverters and battery strings live on connections that hold their resistance for decades in sun and heat. Changzhou DLX Alloy Co., Ltd. — 12,000 m² nickel-only plant since 2002, 1,200 tonnes per year, ISO9001 with SGS support — builds composite strip for that duty: copper core for stable low resistance, nickel cladding for weldable, corrosion-proof joints, clad ratio and dimensions per drawing, inspected per batch before it ships.
A: The copper core keeps connection resistance — and therefore heat — low, while the nickel cladding provides a clean weldable surface with corrosion protection for outdoor service.
A: No — no grade designation applies. The specification is the construction: copper core, nickel cladding, clad ratio and dimensions, all per drawing.
A: Construction (single or double-side cladding), clad ratio, thickness, width, length and surface finish, all per drawing.
A: Solar bus connections, inverter terminals and renewable energy components that need low resistance plus weldability.
A: MOQ is confirmed per drawing; samples available on request (shipping at customer's cost). Lead time: 7-15 days.
