Import Bismuth Ingot — Buy in Bulk from Supplier in China

Bismuth ingot from Zhuzhou Sinotech Industries Co.Ltd is an industrial-grade metal supplied with purity ranging from 99.99% to 99.997%, placing it in the upper tier of commercially available bismuth grades. Each shipment is packaged in plywood cases with a total weight of approximately 1000 kg, suited to bulk procurement by manufacturers and metal traders. The ingot form factor allows straightforward melting and alloying in downstream processes, which is critical for buyers integrating bismuth into casting operations or master alloy production.

The material derives its value from bismuth's distinctive physical properties: a low melting point of 271.5 degrees Celsius, minimal thermal neutron cross-section, and pronounced diamagnetism. These characteristics make it irreplaceable in applications requiring fusible alloys, thermal imaging sensor components, and pharmaceutical compounds such as bismuth subsalicylate. Standard commercial bismuth is typically produced via electrolytic refining or zone refining, with 99.99% purity representing the threshold for most industrial uses; the 99.997% grade approaches semiconductor and research-grade thresholds.

Buyers in electronics, low-melting alloy manufacturing, and chemical synthesis sectors source bismuth ingot for its non-toxicity relative to lead and its expansion upon solidification, which ensures dimensional accuracy in castings. The supplier offers FOB and CIF Incoterms, though exact MOQ and lead time should be confirmed directly with Zhuzhou Sinotech Industries Co.Ltd. Prospective importers should verify certificate of analysis documentation for each lot, request sample assay data, and clarify whether 99.997% purity is guaranteed or represents a typical batch analysis.

Zhuzhou Sinotech Industries Co.Ltd is located in Liyu Industries Garden, Zhuzhou, Hunan Province, China. The supplier holds an imported tier designation and a harbor trust tier classification on the platform. The response rate is recorded at 0.00% with zero average response hours, indicating that direct communication through the platform has not been established or documented.

The company profile does not disclose years in operation, facility size, annual output, or specific quality management certifications. The listing emphasises purity levels, plywood case packaging, and Incoterms flexibility, but does not state ISO certification, factory audit results, or client references. Buyers should conduct independent due diligence, request company registration documents, and verify production capacity through direct outreach before committing to orders.
