Factory-Direct from Changzhou, China | Custom Sizes 3-300 mm Per Drawing | ISO 9001 & SGS Certified
Buyers order custom size nickel bar two ways: stocked diameters for standard sizes, and production to drawing for everything else. This page covers both routes in Ni200 (UNS N02200) and Ni201 (UNS N02201), annealed, in four surface states and cut to the length the drawing calls for. Stock holds 8 mm, 10 mm, 12 mm and 20 mm; diameters from 3 mm to 300 mm and lengths to 6000 mm are produced to drawing. Every lot ships factory-direct from Changzhou with a mill test certificate (EN 10204 3.1).

Technical Details
Reading a Custom Bar Drawing
Four variables drive a custom order: diameter, length, cross-section and surface. Diameter sets the tooling path, length sets how the bar is cut and bundled, cross-section decides whether a round is drawn or a shaped section is rolled, and surface governs how much material the first machining operation removes. A drawing that states tolerance and finish alongside the dimension is quoted without a follow-up question, and where the drawing is silent, the offer names the values the mill will work to. Grade composition limits are set out in the pure nickel series.
From Drawing to Confirmed Offer
The drawing is reviewed against the standard works check before anything is scheduled. What comes back is an offer naming the grade, the dimension and the surface, so the values the mill will produce sit on the order. Non-standard sizes are quoted individually because the rolling and drawing sequence changes with the dimension, and the offer states the delivery that follows from it.
Sections and Lengths Beyond Round Bar
Round bar is the default, and the same grades are produced as hexagonal and square sections to drawing. A shaped section is rolled to the ordered profile and then straightened, so the corner radius and the across-flats dimension are fixed on the drawing. Lengths run to 6000 mm, and cut-to-length orders are bundled for the handling the shop has: full bars where a bar feeder takes them, cut pieces where the machine bed is shorter.
Rolled and Drawn to Dimension
A diameter outside the stock list is produced from the melt. The material is rolled and drawn to the ordered dimension, then annealed and inspected as its own lot, and it carries the chemistry and the documentation of any other order off the pure nickel rod and bar line. Custom and stock bar are made to one grade standard; what differs is the schedule, since a non-standard dimension takes the line through its own sequence of passes.

Quality Assurance
Every custom lot is measured against the drawing before packing, and its composition and mechanical results are recorded on the mill test certificate (EN 10204 3.1) issued for that lot. ASTM B160 and GB/T 4435 references are included for incoming inspection.

Applicable Standards
Ni200/Ni201: ASTM B160 (Nickel Rod and Bar), UNS N02200/N02201. N4/N6 Chinese-grade equivalents: GB/T 4435. Export documentation per EN 10204 3.1.

References
Material data references ASTM B160; corrosion and physical property data reference ASM Specialty Handbook: Nickel, Cobalt, and Their Alloys and standard engineering sources; batch-level composition and mechanicals are verified against mill test certificates and in-house inspection records.
Packaging & Delivery
Bar is supplied in bundles with protective wrapping, packed in export wooden cases, and labeled with grade and size. In-stock diameters dispatch in 3-7 days; standard production runs 7-15 days, and custom sizes 15-30 days per drawing. Worldwide shipping is quoted per destination.

FAQ
Q: How does a custom-size order work?
A: Send the drawing or specification. The dimension, surface and tolerance are confirmed in the offer before production is scheduled.
Q: Which sizes are in stock?
A: 8 mm, 10 mm, 12 mm and 20 mm dispatch in 3-7 days. Other diameters from 3-300 mm and lengths to 6000 mm are produced per drawing in 15-30 days.
Q: Can you supply hexagonal or square bar?
A: Yes: round, hexagonal and square sections are produced per drawing under the same grade program.
Q: Can you make stove or furnace heating elements?
A: No. Resistance heating elements are made from NiCr and FeCrAl alloys. Pure nickel's resistivity of 0.096 μΩ·m makes it a conductor rather than a heating element.
Q: What is the difference between Ni200 and Ni201?
A: Carbon content. Ni200 allows up to 0.15% carbon for general service, and Ni201 holds carbon to 0.02% for parts that run at temperature.
Q: What export documents do you provide?
A: EN 10204 3.1 mill test certificates recording actual lot chemistry and mechanicals, with ASTM B160 / GB/T 4435 references for incoming inspection.
Q: What is the minimum order quantity?
A: MOQ is 10 kg.
Q: How is pricing determined?
A: Quoted by grade and size once the drawing or specification is received.
Q: What payment terms are accepted?
A: L/C, T/T, Western Union and MoneyGram.
