ISO9001 & SGS Certified | Since 2002 | Custom Composite Strip | 7-15 Day Ship
Overview
This copper-nickel composite strip is built for energy storage 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.
Dimensions & Tolerances

Key Strengths
Low resistance — copper core keeps connection resistance stable, limiting heat in ESS 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 Energy Storage
Energy storage systems carry real current for years. In a connection, resistance is heat: the lower the resistance of the tab and joint, the smaller the I²R loss and the cooler the pack runs. The copper core of this composite strip 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 pack 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: energy storage battery pack connections, bus connections, terminals and current-carrying joints. 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.

About DZX
ISO9001 and SGS certification frame every production step at Jiangsu DZX Technology Co., Ltd. Founded in 2002, DZX grew from resistance alloys to Inconel, Monel, Hastelloy and nickel-based products, and applies the same quality discipline to copper-nickel composite strip: per-batch inspection, traceable records and material certificates with the shipment.
FAQ
Q1: Why use copper-nickel composite in energy storage?
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: Energy storage battery pack connections, bus connections and current-carrying joints 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.
