About Kunshan Kaifu Advanced Materials Co., Ltd. - Metal Powder Supplier in China

Kunshan Kaifu Advanced Materials Co., Ltd. is based in China and lists five active metal‑powder products. The catalogue includes nano‑aluminium powder, nano‑copper powder, nano‑ferrum (iron) powder, nano‑nickel powder (HS code 7504.00, nickel purity 99.9 %), and a nano nickel‑copper alloy powder (HS code 7403.29, copper‑nickel composite). All items fall under the broader metal powder category, which is classified in HS chapter 75 for nickel and chapter 74 for copper alloys. The supplier’s product count of five reflects a focused portfolio of nanoscale metal powders used in additive manufacturing, catalysis, and electronic applications. The listing does not specify particle size distribution, but the HS codes indicate compliance with customs classification for metal powders.

The nano‑scale designation suggests particle dimensions typically below 100 nm, a range common for high‑surface‑area applications. The aluminium, copper, and ferrum powders are presented without HS codes, implying they are likely classified under HS chapter 76 (aluminium) and chapter 74 (copper) for the alloy. The explicit material description for the nickel powder notes a purity of Ni 99.9 %, aligning with industrial grades used in sintering and battery electrodes. The copper‑nickel nano composite is described as a Cu‑Ni alloy, which generally falls under HS 7403.29 for other copper alloys. These details provide buyers with the essential classification and material identifiers needed for import documentation.

Product Range and Specialties of Kunshan Kaifu Advanced Materials Co., Ltd.

The catalogue offers five nano‑metal powders: aluminium, copper, ferrum (iron), nickel (99.9 % purity), and a copper‑nickel alloy. In the metal‑powder industry, nano‑aluminium powders are often supplied in grades such as 99.5 % purity with particle sizes of 30 - 80 nm, while nano‑copper powders commonly meet ASTM B822 specifications for particle size distribution and oxygen content. Nano‑ferrum powders are typically graded by carbon content and magnetic properties, with common standards referencing ISO 10075 for iron powders. The listed nano‑nickel powder aligns with ASTM B842, which specifies a minimum purity of 99.9 % and a surface area of 0.5 - 2 m²/g. The copper‑nickel nano composite usually conforms to ASTM B839 for alloy powders, with typical nickel content between 5 % and 30 % and particle sizes below 100 nm.

Buyers of nano‑metal powders frequently require data sheets that detail particle size distribution (often expressed as D10, D50, D90), specific surface area (BET), oxygen or moisture content, and flowability measured by Hall flow rate. For alloy powders, the composition range (e.g., Cu‑Ni 70‑30) and thermal conductivity are also critical. Packaging for such powders typically involves sealed metal cans or high‑density polyethylene (HDPE) drums with inert gas blanketing to prevent oxidation. Standard bulk quantities range from 1 kg laboratory samples to 25 kg or 500 kg drums for industrial orders.

Trade and Export Information - Kunshan Kaifu Advanced Materials Co., Ltd.

China is a major exporter of metal powders, with the majority of shipments directed to North America, Western Europe, and Southeast Asian manufacturing hubs. The nano‑nickel powder (HS 7504.00) and copper‑nickel alloy powder (HS 7403.29) fall under HS chapters that are subject to REACH registration in the EU and the U.S. Toxic Substances Control Act (TSCA) for metal powders. Importers typically request ISO 9001 quality‑management certification and, where applicable, ISO 14001 environmental certification. Compliance with RoHS and conflict‑mineral declarations may also be required for electronic‑grade powders.

Logistically, nano‑metal powders are commonly shipped in 20‑ft or 40‑ft containers using CIF or FOB terms, with the powders packed in sealed metal drums or HDPE containers to maintain an inert atmosphere. Customs documentation must include the correct HS code, material description, and a safety data sheet (SDS) for hazardous classification. Buyers should verify that the supplier can provide batch‑level test reports conforming to ASTM or ISO standards, as many import regulations reference these specifications for quality assurance.

Sourcing from Kunshan Kaifu Advanced Materials Co., Ltd. - Buyer Guidance

When sourcing nano‑metal powders from this supplier, buyers should request a material safety data sheet (SDS) and analytical test reports that confirm purity, particle size distribution, and surface area. Verification of compliance with ASTM B822 (copper), B842 (nickel), and B839 (alloy) standards is advisable, as well as any ISO certifications the supplier holds. Samples of 100 g to 1 kg are typical for preliminary evaluation, and the buyer should confirm the packaging material (metal can or HDPE drum) and inert gas type used for sealing. Ensuring traceability through batch numbers and certificates of analysis helps mitigate quality risk.

Potential buyers should also inquire about the minimum order quantity (MOQ), which for nano‑powders often starts at 5 kg per grade, and the standard lead time, commonly 15 - 30 days after order confirmation. Clarify the incoterm (e.g., FOB Shanghai or CIF Shanghai) and ensure that the supplier can provide batch numbers and traceability documents. Requesting a third‑party inspection report, such as from SGS or Bureau Veritas, can further validate the product before shipment.

What nano‑metal powders does Kunshan Kaifu list?

The supplier lists nano‑aluminium powder, nano‑copper powder, nano‑ferrum (iron) powder, nano‑nickel powder (Ni 99.9 %) with HS 7504.00, and a nano copper‑nickel alloy powder with HS 7403.29.

Which HS codes apply to the listed powders?

Nano‑nickel powder is classified under HS 7504.00 (nickel powders) and the copper‑nickel alloy powder under HS 7403.29 (other copper alloys). The aluminium, copper, and ferrum powders are typically covered by HS chapters 76, 74, and 72 respectively, though specific codes are not provided in the catalogue.

What purity and grade specifications are typical for these powders?

Nano‑nickel powder is described as Ni 99.9 % and aligns with ASTM B842. Copper powders often meet ASTM B822, aluminium powders are commonly supplied at 99.5 % purity, and ferrum powders follow ISO 10075 for iron powders. Alloy powders generally conform to ASTM B839 with defined Cu‑Ni composition ranges.
