Battery tab connections live by one rule: the joint must carry current without hot spots and weld without surprises. This copper-nickel composite strip answers with a copper core for low electrical resistance and nickel cladding for a clean, weldable surface — the combination battery pack makers use for tab connections. No grade designation applies; construction, clad ratio and dimensions are built per drawing and locked at order confirmation. Every batch is inspected against the drawing and ships with documentation.

MOQ and exact tolerances are confirmed per drawing.
A battery tab has to do three jobs at once: carry current, take a weld and survive the environment. The copper core carries current with low electrical resistance, the nickel cladding provides a surface that welds cleanly and resists corrosion — the reason copper-nickel composite is the material of choice for tab connections.
Spot weld consistency depends on surface condition and layer uniformity. The nickel cladding is kept clean and oxide-free, and layer uniformity is confirmed per drawing, so weld nuggets form consistently across the strip. Welding parameters are confirmed against your process at order time.
The copper core reduces tab resistance compared with full-nickel tabs, lowering heat generation at the joint. Exact resistance depends on the core/clad ratio and dimensions, which are confirmed per drawing — no indicative values are claimed without the drawing.
Clad ratio, single or double-side cladding, thickness, width, length and surface are all manufactured per drawing. Share the tab geometry and pack configuration, and we confirm the strip specification before production.

Changzhou DLX Alloy Co., Ltd. has manufactured nickel alloys since 2002 in a 12,000 m² factory rated at 1,200 tonnes per year. A battery tab is a small part with a big job: carry current, take a weld, survive the environment. Our approach treats every composite strip as an engineered part — layer ratio, dimensions and surface confirmed against your drawing, inspected per batch, and documented before it ships.
A: The copper core carries current with low electrical resistance, while the nickel cladding provides a weldable surface and corrosion protection — the combination tab connections need.
A: No — no grade designation applies. The specification is the construction: copper core, nickel cladding, clad ratio and dimensions, all per drawing.
A: The nickel cladding is kept clean and oxide-free, and layer uniformity is confirmed per drawing, so weld nuggets form consistently. Welding parameters are confirmed against your process.
A: Clad ratio, single or double-side cladding, thickness, width, length and surface finish, all per drawing.
A: MOQ is confirmed per drawing; samples available on request (shipping at the customer's cost). Lead time: 7-15 days.
