Kunshan Kaifu Advanced Materials Co., Ltd.

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.

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.
