ISO9001 & SGS Certified | Since 2002 | Custom Composite Strip | 7-15 Day Ship
This copper-nickel composite strip is built for automotive and NEV 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. Every batch is inspected and documented, so the connection you qualify stays the connection you ship.

Key Strengths
Low resistance — copper core keeps connection resistance stable, limiting heat in automotive current paths.
Weldable surface — clean nickel cladding for repeatable welds and solder joints.
Corrosion protection — the cladding shields the connection in service.
Custom per drawing — clad ratio, thickness, width and length confirmed at order.
Consistent across volume — per-batch inspection and documentation on every order size.
Technical Deep Dive
1. Why Low Resistance Matters in Automotive
Automotive connections carry high current under vibration and temperature swing. 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 life. The copper core delivers that low resistance, while the nickel cladding keeps the weld surface stable.
2. Construction and Layer Design
| Layer | Role |
|---|
| Copper core | Low electrical resistance, current carrying |
| Nickel cladding | Corrosion resistance, weldable surface |
| Clad ratio | Confirmed per drawing |
3. Custom Capability
Construction (single or double-side cladding), clad ratio, thickness, width, length and surface finish are all manufactured per drawing. Share the component design and the drawing, and we confirm the strip specification before production.
4. Quality and Compliance
| 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 |
5. Application Guidance
Typical use: automotive connectors, NEV battery tabs, terminals and fuse components. Grade-free construction per drawing gives design freedom across these duties.
Pricing & Quotation
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.

FAQ
Q1: Why use copper-nickel composite in automotive connections?
A: The copper core keeps connection resistance — and therefore heat — low, while the nickel cladding provides a clean weldable surface with corrosion protection.
Q2: Does this composite have a grade?
A: No — no grade designation applies. The specification is the construction: copper core, nickel cladding, clad ratio and dimensions, all per drawing.
Q3: What can be customized?
A: Construction (single or double-side cladding), clad ratio, thickness, width, length and surface finish, all per drawing.
Q4: What is it used for?
A: Automotive connectors, NEV battery tabs, terminals and fuse components that need low resistance plus weldability.
Q5: What are the MOQ and delivery terms?
A: MOQ is confirmed per drawing; samples available on request (shipping at customer's cost). Lead time: 7-15 days.
