AI-Powered supplier vetting

SummaryHangzhou Ualloy Material Co., Ltd. is a China-based manufacturing factory established in 2012, focused on resistance alloys, copper-nickel alloy strips, FeCrAl alloys, and precision alloys. It operates from a 2,195 m² plant with two production lines, a complete stated process from melting through slitting, and testing equipment. The supplier reports ISO9001:2015 certification, self-operated import and export rights, and exports accounting for 51%–70% of sales. Its stated workforce includes 15 employees, one R&D engineer, and fewer than five quality-control staff. The available trade records show three single-transaction buyer cases in Brazil during April–May 2025. Evidence supports established manufacturing and export operations, but after-sales service, financial credibility, customization execution, and broader customer performance cannot be fully assessed from the provided information.
Supplier typeThe supplier is explicitly identified as a factory/manufacturer and a limited company located in Fuyang, Hangzhou, China. Its 2,195 m² manufacturing plant and stated alloy-strip production specialization support classification as a manufacturing supplier rather than only a trading intermediary.
CertificationsThe supplier reports holding an ISO9001:2015 management-system certificate. This is explicit evidence of quality-management certification, although the provided information does not include certificate scope, issuing body, or validity dates.
Production capacityThe supplier reports a 2,195 m² manufacturing plant, two production lines, and a full process covering melting, surface cleaning, rolling, and slitting, supported by testing machines. These details explicitly demonstrate in-house manufacturing infrastructure for alloy-strip products.
Client casesTrade records identify three Brazilian buyer companies and product descriptions involving nickel bars, Ni80Cr20 heating material, and steel-related goods, with one transaction recorded for each case during April–May 2025. These records provide evidence of named overseas customer transactions, but the limited number of transactions does not establish long-term relationships, repeat orders, or customer satisfaction.
