Material: high-conductivity electrolytic copper base with a uniform nickel electroplated surface layer.
Key features & advantages
l Corrosion resistance: nickel barrier protects copper from oxidation, tarnish, and many corrosive environments (marine, industrial).
l Improved solderability/weldability: uniform plating supports reliable brazing, soldering, and resistance welding processes.
l Enhanced wear and contact performance: nickel surface reduces fretting and contact degradation in connectors and sliding contacts.
l Good thermal and electrical performance: maintains copper’s high conductivity while improving surface contact quality.
l Vacuum and high-temperature stability: suitable for many vacuum systems and elevated-temperature assemblies when properly specified.
l Dimensional consistency: precision rolling and plating delivers tight thickness tolerances for automated assembly.
l Cost-effective alternative to solid nickel or plated precious metals where silver/gold are not required.

Basic technical data
＞ Base metal: Electrolytic copper (Cu-ETP)
＞ Copper purity: ≥ 99.9% Cu (or per customer spec)
＞ Nickel plating: Electrolytic nickel (bright or matte)
＞ Typical nickel thickness: 0.5 µm — 10 µm (standard 1–5 µm; customizable)
＞ Surface resistivity impact: negligible on bulk conduction; contact resistance improved vs bare copper
＞ Conductivity (base copper): ~58 MS/m (100% IACS = 58 MS/m)
＞ Tensile strength (typical, strip form): depends on temper; example annealed: 120–220 MPa; cold-rolled: up to 350 MPa
＞ Elongation: varies with temper; typical 10–30%
＞ Operating temperature (plating stability): continuous up to ~300 °C in air (dependent on environment and plating thickness)
＞Solderability: good with standard lead-free solders after appropriate flux/cleaning
＞Adhesion: > 1.5 N/mm (typical peel/pull test; custom spec available)
＞ Surface finish options: bright nickel, matte nickel, passivated nickel, lacquered/protected
＞Compliance/testing: RoHS, REACH support; custom testing (salt spray, cyclic corrosion, thermal cycling) available
Salt spray (ASTM B117) and cyclic corrosion testing for marine/industrial qualification.
Electrical resistance and conductivity certification.
Dimensional and surface roughness reports; custom QA inspection plans available.
Prototype/sample service and small-batch pilot runs for design validation.
Avoid abrasive machining of plated surface unless re-plating is planned; use controlled grinding/cutting procedures.
Select plating thickness and post-treatment based on expected contact cycles, environment (salt spray, chemical exposure), and solder/weld method.
Store coils in dry, clean conditions; apply anti-tarnish film if long-term storage in humid environments is expected.
For vacuum/high-temperature use, request material-specific outgassing and thermal stability data.
Custom alloy base (special copper grades), nickel thickness, surface finish and pre-treatment available.
Prototype and qualification support: small runs, test reports, and assisted qualification testing for EV, aerospace, medical, and defense customers.
Nickel-plated copper belt/strip offers a balanced solution where high electrical conductivity must be combined with corrosion resistance, surface durability, and reliable assembly performance.
