The shortest supply chain for nickel rod runs from the melt to your machine. High temperature pure nickel rod and bar in Ni200 (UNS N02200) and Ni201 (UNS N02201) is produced on our own line in Changzhou, China — the factory that melts it is the factory that quotes it — with 8, 10, 12 and 20 mm diameters in stock and other sizes from 3-300 mm per drawing. Ni201's low-carbon structure keeps the bar sound in sustained service above 315°C, where carbon precipitation would embrittle higher-carbon grades. Mill test certificates (EN 10204 3.1) accompany every lot.

Pure nickel has a real high-temperature envelope, and it is worth stating precisely. Its signature hot application is concentrated and molten caustic alkali service — caustic evaporators and handling equipment at 300-450°C are built from pure nickel because few metals match it there. It also resists oxidation in air up to roughly 800°C through a protective oxide scale. What it is not: it is not a gas-turbine or combustion-chamber material (those are nickel superalloys), its strength falls steadily above about 600°C like any unalloyed metal, and high-temperature sulfur-bearing atmospheres attack nickel severely through low-melting nickel sulfides. If your service is caustic, oxidizing air, or reducing media within these limits, Ni200/Ni201 rod is a documented answer — if it runs hot sulfur, send the composition and we will steer you to a suitable alloy instead.

The full shape and surface program for Pure Nickel Bar covers round, hexagonal and square forms with black, peeled, polished and cold drawn surfaces.

• Ni201 low-carbon grade for sustained service above 315°C; Ni200 for general chemical and mechanical duty.

• Proven in concentrated and molten caustic alkali service at 300-450°C.

• Factory-direct supply from our own Changzhou line — drawing, grade and delivery confirmed by the mill.

• 8-20 mm stock with 3-7 day dispatch; 3-300 mm per drawing.

• Mill test certificates (EN 10204 3.1) and export documentation on every shipment.

Nickel 200/201 keep useful mechanical properties to roughly 600°C in structural service, and resist oxidation in air to about 800°C. The metal's celebrated hot duty, though, is caustic: concentrated sodium and potassium hydroxide at 300-450°C, where nickel's combination of corrosion resistance and strength is the reason evaporators, concentrators and caustic piping are specified in pure nickel. Above 600°C for load-bearing parts, or in sulfur-bearing atmospheres at temperature, the design should move to a nickel alloy or other family — and our engineers will tell you so rather than take the order.

The two grades differ only in carbon — Ni200 at 0.15% max, Ni201 at 0.02% max — and that difference appears in service. Held between roughly 315°C and 760°C, carbon in Ni200 can precipitate at grain boundaries and embrittle the metal over time; Ni201's low carbon avoids that mechanism, which is why sustained high-temperature duty is specified in the Pure Nickel Series as Ni201. Below that range, or where exposure is intermittent, Ni200 remains the general-purpose workhorse.

Buying rod from the factory that melts it removes a layer of the supply chain: the drawing goes straight to the production line, the grade and composition come from the melt records, and the quote is the mill's own number rather than a trader's margin. Stocked diameters dispatch in 3-7 days; non-stock diameters run in 7-15 days; custom lengths and tolerances are confirmed at 15-30 days per drawing. Questions on machinability, surface or heat treatment reach the people who make the bar.

Every shipment leaves with a mill test certificate (EN 10204 3.1) recording actual lot composition and mechanical properties, backed by melt and lot traceability and export documentation arranged per destination. With export experience across 60+ countries, the paperwork — MTC, packing lists, commercial invoices, origin documentation — is handled on our side so the bar clears customs and arrives on schedule.

Annealed bar: tensile strength ≥462 MPa, 0.2% yield strength ≥148 MPa, elongation ≥35%, hardness 90-120 HB. Physical constants: density 8.908 g/cm³, melting point 1435-1446°C, electrical resistivity 0.096 μΩ·m, thermal conductivity (Ni200) 70.2 W/m·K, coefficient of thermal expansion (Ni200) ≈13.3 µm/m·K, magnetic (ferromagnetic below Curie point 358°C).

Produced under ISO 9001 quality systems and SGS-verified processes, each bar batch passes chemical composition analysis and dimensional and surface inspection before packing. Mill test certificates (EN 10204 3.1) record the actual lot composition and mechanical properties, and every bar carries melt and lot traceability.

Ni200/Ni201: ASTM B160 (Nickel Rod and Bar). Export documentation per EN 10204 3.1. N4/N6 Chinese-grade equivalents follow GB/T 4435 on request.

Material data follows ASTM B160; caustic-service and high-temperature guidance references the Nickel Institute (caustic handling in nickel equipment) and ASM Specialty Handbook: Nickel, Cobalt, and Their Alloys; batch-level composition is verified against mill test certificates (EN 10204 3.1) and in-house inspection records.

Bar is supplied in bundles with protective wrapping, packed in export wooden cases, and labeled with grade, size, surface and weight. Worldwide shipping with full export documentation is quoted per destination. In-stock diameters dispatch in 3-7 days, standard production in 7-15 days, and custom sizes in 15-30 days per drawing. Payment by L/C, T/T, Western Union or MoneyGram.

DZX Alloy has melted and processed nickel-based materials in Changzhou, Jiangsu since 2002, under ISO 9001 and SGS quality systems. Because production and export sit in the same building, the nickel rod you order is quoted by the mill, made on its own line, and shipped with its own certificates — the factory-direct relationship that 60+ export markets have relied on for repeat orders of the same UNS grades, the same tolerances, and the same documentation.

Q: What is the brand name of this product?
A: The brand name is DZX Alloy (Jiangsu DZX Technology Co., Ltd.).

Q: What grades are available?
A: Ni200 (UNS N02200) and Ni201 (UNS N02201) — the two ASTM commercial-grade wrought nickels. N4/N6 are available on request.

Q: When should I choose Ni201 over Ni200?
A: Above roughly 315°C in sustained service, choose Ni201 — its 0.02% max carbon avoids the grain-boundary carbon precipitation that can embrittle Ni200 (0.15% max C) between 315°C and 760°C.

Q: What high-temperature service is pure nickel suited to?
A> Concentrated and molten caustic alkali handling at 300-450°C is the flagship application; oxidation resistance extends to roughly 800°C in air. It is not suited to hot sulfur-bearing atmospheres or load-bearing service above about 600°C.

Q: What sizes are available?
A: 8 mm, 10 mm, 12 mm and 20 mm diameters are stocked; other diameters from 3-300 mm and lengths up to 6000 mm are produced per drawing.

Q: What is the minimum order quantity?
A: MOQ is 10 kg.

Q: What is the delivery time?
A: 3-7 days for in-stock diameters, 7-15 days for standard production, 15-30 days for custom sizes (per drawing).

Q: Do you provide export documentation?
A: Yes — mill test certificates (EN 10204 3.1), packing lists, commercial invoices and origin documentation are arranged per destination.

Q: What are the accepted payment terms?
A: L/C, T/T, Western Union and MoneyGram are accepted.
