Wuhan Xinrong New Materials Co., Ltd

Based in Wuhan, China, Wuhan Xinrong New Materials Co., Ltd lists five active products across metal products, tailoring needles, industrial chemicals and metal powders. The catalogue includes a High Purity Bismuth Needle, an Indium Bar classified under HS code 8112.92, Indium Oxide, a High Purity Bismuth Trioxide (HS code 2825.50) in light‑yellow powder form, and a Bismuth Telluride Bar (HS code 2804.50). The listed materials feature purities of 99.9999 % for the indium bar and 99.99 - 99.999 % for the bismuth telluride alloy. All items are described with specific chemical compositions such as Bi₂O₃ and Bi₂Te₃.

The supplier’s product set focuses on high‑purity metals and compounds used in semiconductor, thermoelectric and specialty alloy applications. The High Purity Bismuth Needle is presented without an HS code but falls under the metal products chapter. Indium Oxide is offered as a separate chemical, commonly supplied in powder or bulk form. The bismuth compounds are described as light‑yellow powder and alloy bar respectively, indicating typical physical forms for export. No certifications are listed in the supplied data, so buyers should verify compliance with standard material certifications.

Wuhan Xinrong’s catalogue covers a narrow but technically demanding range: a high‑purity bismuth needle, an indium bar of 6N (99.9999 %) purity, indium oxide, a high‑purity bismuth trioxide powder, and a bismuth‑telluride alloy bar with 4N‑5N (99.99 - 99.999 %) purity. In the broader market, indium bars are often supplied in 6N to 7N grades for thin‑film semiconductor processes, with specifications for oxygen content below 5 ppm. Bismuth trioxide powders are typically graded by particle size (e.g., <10 µm) and moisture content (<0.1 %). Bismuth‑telluride alloys used in thermoelectric modules are commonly offered in bar or ingot form with tight control of carrier concentration and resistivity, and industry standards reference IEC 61753 for thermoelectric material performance. Tailoring needles made from bismuth are less common, but metal needles generally require dimensional tolerance within ±0.05 mm.
