Start with a Sample — Pure Nickel Bars with 10 kg Trial MOQ

Procurement teams rarely get to validate a material before the first real order — datasheets are trusted on faith, and a mismatch is discovered only after the batch fails. Trial-based buying changes that: start with a free 0.5 kg sample of N6 or Ni200, run your machining, welding or corrosion checks, and confirm the 462 MPa annealed baseline on real metal. If the grade you need is N4 or Ni201, the sample is charged but refunded on your first 50 kg+ order. Custom bars start at a 10 kg MOQ with tolerances locked per drawing, and every delivery carries EN 10204 3.1 MTC. The material you verify is the material you scale.

• Free 0.5 kg sample for N6/Ni200 — verify before committing volume.
• 10 kg trial MOQ — the first production order stays small and low-risk.
• N4/Ni201 sample fee refunded on first 50 kg+ order.
• Custom sizes per drawing, with EN 10204 3.1 MTC on every batch.
• Annealed tensile ≥462 MPa baseline — testable on the sample itself.

A sample is only worth sending if it answers the questions that matter. DLX recommends a four-point check on the 0.5 kg sample: machine a test piece to confirm cutting behavior, run a weld or braze trial if joining is part of your process, expose a coupon to your service environment for corrosion checks, and compare the mill certificate against the chemical and mechanical tables below.

Diameter, length, straightness and surface are confirmed against your drawing before production, and tolerances are locked at that review. The drawing sent with the trial order defines the production standard from day one.

The numbers on the datasheet are the numbers on the sample: ≥462 MPa tensile strength, ≥35% elongation and 90-120 HB hardness in the annealed condition, with a density of 8.908 g/cm³ and a melting point of 1435-1446°C. Verify them once, then scale with confidence.

Not sure which grade to start with? The choice follows the service condition. N4 (NP1) is the highest-purity option for vacuum-electronics duty. Ni201 serves higher-temperature applications. Ni200 covers battery and chemical service. N6 (NP2) is the workhorse for industrial corrosion duty and the most economical option — a sensible starting point for most first trials.

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. Samples and in-stock diameters can be dispatched promptly; production lead time is 15-25 days after drawing and grade confirmation. Every order ships with the complete export documentation set: packing list, commercial invoice and mill test certificate.

Changzhou DLX Alloy Co., Ltd. built its customer policy around a simple idea: a buyer should be able to verify a material before committing volume. That is why the free 0.5 kg sample program and the 10 kg bar MOQ exist — not as marketing lines, but as standard practice backed by a nickel-only 12,000 m² facility producing 1,200 tonnes a year. The factory has been refining nickel alloys since 2002, and the low-barrier entry it offers today comes from that long production record: DLX can afford to let buyers test first because the material performs.

Yes — 0.5 kg free sample for N6 and Ni200. For N4 and Ni201 the sample is charged, and the fee is refunded on your first 50 kg+ order.

Four checks are recommended: a machining test, a joining trial, a corrosion coupon in your service environment, and a comparison of the mill certificate against the published composition and properties.

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.

N6 (NP2) is the most economical option and a sensible starting point for most industrial applications; choose N4, Ni201 or Ni200 when purity, temperature or chemical duty is the deciding factor.

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).
