DLX Copper Nickel Strips With High Conductivity & Low Vapor Pressure

Overview

Copper nickel strip is ordered when you need it — and common grades stay in stock for 3-7 day delivery. Our copper nickel strip offers high conductivity and low vapor pressure, with low electrical resistance, good heat and corrosion resistance, and easy processing and lead-soldering. Available in catalog grades from CuNi1 to CuNi44 (including CuNi10 and CuNi30), in strip thicknesses of 0.5-2.5 mm and widths of 5-180 mm, with custom sizes confirmed against your drawing — from our ISO 9001 certified nickel-only line.

Dimensions & Tolerances

Strip is produced in thicknesses of 0.5-2.5 mm and widths of 5-180 mm, with custom sizes and tolerances confirmed against the drawing before production and locked in the batch record. Wire, flat wire and rod forms are also available.

Key Strengths

• In stock, fast delivery — common grades ship in 3-7 days for small lots.
• High conductivity — low electrical resistance for relay and circuit-breaker service.
• Heat and corrosion resistance — stable performance in demanding service.
• Easy processing and lead-soldering — clean forming and joining for component manufacture.
• Wide grade range — CuNi1 to CuNi44, including CuNi10 and CuNi30.

Technical Deep Dive

Grade Range: CuNi1 to CuNi44

The catalog covers twelve copper-nickel grades — CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23, CuNi30, CuNi34, CuNi40 and CuNi44. Grade selection follows the application; chemical composition per grade is confirmed with the mill test certificate.

High Conductivity & Low Vapor Pressure

The strip's low electrical resistance supports service in thermal overload relays, low-resistance thermal circuit breakers and electrical components; low vapor pressure supports vacuum and sealed-component applications. Conductivity and vapor-pressure behaviour are confirmed against the grade and application.

Heat & Corrosion Resistance

Copper-nickel strip resists heat and corrosion, which is why it appears in electrical components and heat-tracing cables that run warm and work in demanding environments.

Applications

• Thermal overload relays
• Low-resistance thermal circuit breakers
• Key components in electrical appliances
• Electric heat-tracing cables
• Vacuum and sealed-component service

Pricing

Copper-nickel strip is quoted per grade, strip size and quantity; pricing is confirmed against the drawing and the current market. No published price bands are listed for this alloy family.

Chemical Composition

Chemical composition per grade (CuNi1-CuNi44) is confirmed with the mill test certificate (EN 10204 3.1) against the order requirement — composition data is verified per batch, not published generically.

Physical Properties

• Conductivity: high, low electrical resistance
• Vapor pressure: low (supports vacuum and sealed-component service)
• Heat resistance: good
• Corrosion resistance: good
• Processability: easily processed and lead-soldered
• Specific density and melting values are confirmed against the grade with the mill test certificate

Specifications

Quality Assurance

Quality control starts at the melt: raw material composition is verified against the grade requirement before rolling, then every batch is gauged for thickness, width and surface condition against the drawing. Batch records link each order back to the melt, and EN 10204 3.1 mill test certificates ship with every consignment.

Applicable Standards

• Copper-nickel alloy strip per applicable ASTM / GB/T standards, confirmed against your drawing and order
• EN 10204 3.1 mill test certificates accompany shipments

References

Material data on this page follows the factory catalog for copper-nickel alloys (grades CuNi1-CuNi44, strip sizes and feature descriptions); application guidance references copper and nickel industry literature (Copper Development Association; ASM Specialty Handbook). Batch-level composition and geometry are verified against mill test certificates (EN 10204 3.1) and in-house inspection records.

Packaging & Delivery

Strip is supplied in coils, edge-protected and moisture-wrapped, packed in cartons and export wooden cases. Documentation — mill test certificates, batch records and packing lists — accompanies every order. In-stock grades ship in 3-7 days; standard production in 7-15 days from confirmed drawing.

About DLX Alloy

Copper nickel is a workhorse alloy — it carries current, resists corrosion and solders cleanly, and it has to do all three consistently. DLX Alloy has run a nickel-only line since 2002 — 12,000 m² of floor space, 10,000 t/yr total capacity, ISO 9001 certified and SGS audited — rolling copper-nickel strip with per-batch composition analysis and EN 10204 3.1 mill test certificates on every shipment.
