Overview

Per-kg pricing for Russian nickel wire is quoted by grade, diameter, quantity and documentation, so buyers in Russia and CIS can compare a quote line by line before ordering. The wire is drawn from 0.025 mm to 10 mm across four commercial-purity grades (N4, N6, Ni200, Ni201), supplied from an ISO 9001 and SGS certified mill, and export orders ship with EN 10204 3.1 mill test certificates.

Where Pure Nickel Wire Sits: Conductivity Versus Resistance

Pure nickel wire is a conductor, with a resistivity of 0.096 μΩ·m, which is why it is specified for current-carrying and structural parts: connectors, leads and supports that need stable resistance and clean welds. Components designed to generate heat through high resistance, such as resistors and resistance heating coils, belong to the high-resistance alloys, nickel-chromium (NiCr) and copper-nickel (CuNi), which are separate product lines. The choice follows the drawing: pure nickel where conductivity carries the current, an alloy where resistance does the work.

Dimensions & Specifications

Micro wire (≤0.05 mm) is available at a 1 kg MOQ; standard wire sizes start at a 5 kg MOQ. Thickness and dimensions are produced to customer requirements within the pure nickel wire range; submit the drawing for confirmation.

Key Strengths

• Graded purity: Ni200 ≥99.2%, Ni201 ≥99.0%, N6 ≥99.5% and N4 ≥99.9% Ni+Co within the Pure Nickel Series, with the grade and batch chemistry stated on the mill certificate.

• Conductivity: resistivity of 0.096 μΩ·m keeps resistance low and predictable in current-carrying parts.

• Thermal conductivity: 70.2 W/m·K (Ni200) spreads heat evenly across a part, which matters where temperature uniformity is the requirement.

• Magnetic behaviour: ferromagnetic with a Curie temperature of 358°C, for parts that interact with a magnetic field.

• Formability: drawing, rolling and forging cover fine diameters, flat sections and complex shapes.

• Service stability: holds against alkaline and reducing media, and against high-temperature oxidation and sulfidation.

Technical Details

What Determines the Price Per Kg

Per-kg pricing follows four variables. First, grade: N4 (≥99.9% Ni+Co) carries the highest price, then Ni201, Ni200, and N6 at the most economical level. Second, diameter: micro wire (0.025-0.05 mm) requires more drawing passes and tighter process control, raising unit cost. Third, quantity and packaging: larger coil orders reduce per-kg cost, while spooled micro wire adds handling. Fourth, documentation: EN 10204 3.1 mill certificates are included on export orders. For a firm per-kg quote, specify grade, diameter, quantity and required documents.

Corrosion Profile: Where Nickel Wire Holds

Pure nickel resists alkaline media, neutral salt solutions and reducing environments, and it forms a dense protective oxide layer in air that limits further attack. At elevated temperature it resists oxidation and sulfidation, which is why it appears in chemical and energy service. The boundary matters: strong oxidizing acids such as nitric acid and hot concentrated sulfuric or hydrochloric acid attack nickel, so the medium, concentration and temperature should be evaluated before the material is specified, and aggressive acid service is a case for surface protection or an alloyed grade.

Four factors drive that performance: the chemical stability of nickel, the dense oxide layer it forms in air, its electrochemical behaviour (low standard potential, high anodic polarization), and a uniform crystal structure that resists attack at the microscopic level. Conditions outside the range above are a grade-selection question, and the medium and the temperature decide which grade is right.

Standards and Documentation for Russian Importers

Wire is supplied to ASTM B164 for Ni200/Ni201 and GB/T 21653 for N4/N6. Export orders to Russia and CIS markets include EN 10204 3.1 mill test certificates covering batch-level chemical composition, dimensions and mechanical properties, together with packing lists and shipping documents as required. The mill runs ISO 9001 and SGS certified systems, and batch records are retained for traceability.

Formability: Drawn, Rolled, Forged

Pure nickel draws and forms readily, covering fine diameters, flat sections and forged or formed shapes. Annealed temper gives the highest formability for bending and coiling, while hard or 1/2 hard temper holds shape in self-supporting structures. State the forming process the line uses, drawing, stamping, winding or welding, and the temper is matched to it.

Packaging & Delivery

Micro and fine wire is wound on spools and packed in carton boxes; larger diameters are supplied as coils in polybags or on spools as requested. Delivery is 7-15 days for standard production, 3-7 days for small in-stock quantities, and 15-30 days for complex custom requirements confirmed against the drawing. Export documentation (EN 10204 3.1 MTC) is prepared for Russian and CIS shipments.

About the Factory

For export buyers, the quote and the mill certificate are the two documents that decide a purchase, so DZX keeps both concrete: a per-kg breakdown by grade and diameter, and EN 10204 3.1 certificates that match the batch. The mill was founded in 2002, holds ISO 9001 and SGS certification, and has shipped 1,000+ product configurations to 60+ countries for 2,000+ partners over 20+ years, with 50+ patents behind its drawing and heat-treatment processes.

FAQ

• How is the price per kg calculated? Price per kg follows grade (N4 highest, then Ni201, Ni200, N6), diameter (micro wire costs more per kg), quantity and packaging, plus documentation. Send grade, diameter, quantity and required documents for a firm per-kg quote.

• Which grade suits the application? For hot service above roughly 315°C, choose low-carbon Ni201 (C ≤0.02%) to avoid carbide precipitation. For room-temperature structural and current-carrying parts, Ni200 is economical; N4 (≥99.9%) is specified where maximum purity is required.

• What diameters and tolerances are available? Round wire from 0.025 mm to 10 mm, in soft, hard or 1/2 hard temper. Dimensional tolerances are locked per drawing at order confirmation; micro sizes (≤0.05 mm) are drawn to the tight end of the range.

• What documents ship with export orders to Russia and CIS? EN 10204 3.1 mill test certificates covering chemical composition, dimensions and mechanical properties, plus packing lists and shipping documents. Batch records are retained for traceability.

• What is the MOQ and sample policy? Micro wire (≤0.05 mm) starts at 1 kg; standard wire at 5 kg. Samples are free for N6/Ni200 (0.5 kg); N4/Ni201 samples are charged and refunded on a first order of 50 kg or more.

• What is the delivery time? Standard production ships in 7-15 days; small in-stock quantities in 3-7 days; complex custom requirements in 15-30 days after drawing confirmation.
