Premium Pure Nickel Bars for High-Temperature Service

High-temperature service punishes materials that cannot hold their properties: oxidation accelerates, strength drifts, and a failed component costs far more than the bar that made it. For service up to the practical limits of pure nickel, grade choice and delivery speed matter equally. Premium pure nickel bars from DLX cover the temperature-relevant grades — Ni201 for high-temperature duty, Ni200 and N6 for general service, N4 for the strictest purity — with a melting point of 1435-1446°C and documented annealed properties. Popular diameters are held in stock and ship within 3-7 days, while custom sizes are produced per drawing with EN 10204 3.1 MTC on every batch. The bar that arrives is the grade, temper and dimension you specified.

• Ni201 for high-temperature service — the grade matched to heat, per grade application data.
• Melting point 1435-1446°C — a documented ceiling for high-temp duty.
• In-stock diameters ship in 3-7 days — heat-resistant material without the wait.
• Four grades on one order — N4/N6/Ni200/Ni201 — match cost to service temperature.
• EN 10204 3.1 MTC with batch traceability on every delivery.

Pure nickel has a melting point of 1435-1446°C, but service temperature is a different question than melting. Ni201 is the grade matched to high-temperature service, with low carbon content that keeps it stable where sustained heat is present. Ni200 and N6 cover general and industrial duty, while N4 (NP1) serves the strictest purity requirements.

For buyers working to a maintenance or production schedule, stock matters. Popular diameters are held in inventory and ship within 3-7 days, with the same EN 10204 3.1 MTC and batch traceability as made-to-order bars. Custom sizes are produced per drawing after confirmation.

Diameter, length, straightness and surface are confirmed against your drawing before production, and tolerances are locked at that review — the same standard for stock and custom bars.

The annealed baseline is documented per heat: at least 462 MPa tensile strength, ≥35% elongation and 90-120 HB hardness — properties that hold across heats so high-temp components machine and perform predictably.

Annealed is the standard temper for high-temperature components that will be formed or machined; cold-worked tempers provide higher strength for structural parts. Specify the target strength or hardness on the drawing and the temper is set accordingly.

Indicative FOB China reference prices for bars; final quotation per grade, size, quantity and temper.

Source: DLX product catalog. N4/N6 per GB system; Ni200/Ni201 per ASTM system.

The 10 kg minimum order for bars covers drawing setup and heat allocation, so tolerances can be locked per drawing; wire and strip products are available at 5 kg MOQ.

Quality control for bars follows the shape, not a generic checklist:

• Incoming: raw nickel verified per heat before processing.
• In-process: diameter, length and straightness checked with calibrated instruments; surface inspected along the full length.
• Final: tensile and hardness testing sampled per heat; chemical composition verified per heat.
• Documentation: EN 10204 3.1 MTC with heat number, test results and full traceability.

Ni200/Ni201 bars are manufactured and tested to ASTM B160; N4/N6 follow GB/T 4435-2010. Testing methods and acceptance criteria follow the drawing specification and applicable standards.

Straight bars are bundled and protected against transit damage; longer lengths travel in export wooden cases, seaworthy-packed for container shipment. In-stock diameters ship within 3-7 days; custom sizes are produced after drawing confirmation. Every order ships with the complete export documentation set: packing list, commercial invoice and mill test certificate.

Changzhou DLX Alloy Co., Ltd. produces the full nickel-based family — from pure nickel to Inconel, Monel, Hastelloy and high-temperature alloys — and that breadth shapes how the company advises on heat. When a buyer asks which pure nickel grade serves a hot process, the answer comes from hands-on production of alloys that run at much higher temperatures. The 12,000 m² nickel-only facility, operating since 2002, keeps every family on a controlled line, so the melting point, temper and traceability promised on the data sheet are exactly what the bar delivers.

Ni201 is the grade matched to high-temperature service, with low carbon content for stability under sustained heat. Ni200 and N6 cover general and industrial duty.

1435-1446°C — a documented property of the pure nickel grades supplied.

In-stock diameters ship within 3-7 days; custom sizes are produced after drawing confirmation with the lead time confirmed at review.

10 kg for custom bars — the minimum covers drawing setup and heat allocation so tolerances can be locked per drawing. Other pure nickel forms, such as wire and strip, are available at 5 kg MOQ.

Every delivery includes EN 10204 3.1 MTC with heat number and batch traceability, backed by ISO9001 and SGS certification. Bars meet ASTM B160 (Ni200/Ni201) and GB/T 4435-2010 (N4/N6).
